Steering Wheel Control Wiring
 

Hello again,
Does anyone have any experience with hooking up the Pac-Swi-Jack steering wheel control interface to a Kenwood 8120?
Where in the dash can I find the wires for the steering wheel?
Any tips on how to program the unit?
Pictures would alo be great too!
Thanks,
Willie

Ok the SWI-JACK uses the White wire to connect to the blue with a yellow strip on the back of the Kenwood radio. The instructions are here:


The information we have on a 2009 Nissan - 370Z , has been generated below.

1. Quick description before we start wiring the SWI-JACK .
The SWI-JACK 's wire color we are going to use is White. This is the White wire on the SWI-JACK , not the vehicle!
The other wires on the SWI-JACK , green, yellow, orange and blue wires are not used for your Nissan 370Z.

This leaves you with a Red, Black and two loop wires. These wires will be discussed down below.

2. Picture of the Nissan 370Z plug.
Connector picture is unavailable. Either we don't have a picture to show or we have to get the wire somewhere else and not at the factory radio harness.

3. Connecting the SWI-JACK 's steering wheel control input wire to vehicle plug.
Connect the SWI-JACK 's White wire to PIN 16 (Blue) with a 150 ohm resistor, PIN 15 (Pink) with a 47 ohm resistor
Connect free ends of resistors to interface's White wire.
Ground the BROWN wire found in the same radio connector.



4. Connecting power and ground wires.
Black wire: Connect the SWI-JACK 's black wire to chassis ground. This is usually a black wire on the aftermarket wire kit.
Red wire: Connect the SWI-JACK 's red wire to a switched +12volt wire. This is usually a red wire on the aftermarket wire kit.

5. Instructions for cutting or not cutting loop wires.
Step A: The purple loop wire does not need to be cut.
Step B: Cut the Brown loop wire in half and insulate both ends.

6. Programming the SWI-JACK with a version number.
The SWI-JACK has to be programmed for version # 3.
1. Press and hold the Program Button on the SWI-JACK while turning on the vehicle to the accessory position. The LED will turn on.
2. Release the Program Button and the LED will turn off.
3. Press the Program Button 3 times. Each time you press and release the Program Button, the LED will turn on and off. Once you press the Program Button 3 times, wait for 3 seconds. The LED will flash 3 times indicating it is programmed for version 3. If it flashes the wrong version number, you will have to start all over at step 1 above in this section. Turn the key off.
4. Once you have programmed the correct version number, you will not have to do these steps again. If you need to reprogram the steering wheel control, you can go directly to the next section.

7. Programming the SWI-JACK to learn steering wheel control functions.
1. Turn the key to the accessory position (you do not need to hold the Program Button at this time). The LED will flash 3 times. This indicates it is programmed for version 3.
2.
Press the Program Button until the LED turns on, then release the button (This will erase all previous learned steering wheel control functions). The SWI-JACK is now ready to learn a command from the steering wheel.

3.
The SWI-JACK must be programmed in the specific order shown in the chart below. If a function is not needed, it may be skipped. Adjust the Radio Select switch on the side of the SWI-JACK according to the chart. Alpine = 1, JVC = 2, Kenwood = 3, Clarion = 4 and Blaupunkt = 5.

4. With the LED on, press your steering wheel button until the light goes out and hold for one second more.
5. Release and the LED should come back on. If it does not please double check all connections and verify for correct version programming.
6. Repeat step 4 and 5 to program additional steering wheel buttons in the order corresponding to the chart above for your SWI interface.
7. If you come across a command in the chart that your steering wheel does not have, or you do not want to program, press the Program Button on the side of the SWI interface.
8. The LED will flash once rapidly and then stay on confirming that you have successfully skipped that command and are ready for the next button.
9. When you are done programming all the buttons, wait for about 7 seconds. The LED will flash 3 times indicating it is done programming. The LED will then flash 3 times indicating the version number.


8. Testing the SWI-JACK .
1. Connect the plug to back of radio's steering wheel input jack or harness.
2. With the vehicle on, press a steering wheel button to control the stereo. The SWI-JACK should control the aftermarket stereo with the function you taught it. Test all other buttons.
3. If the interface does not control the radio as the steering wheel indicates, the buttons were either pressed in the wrong order or a step was not skipped properly. Return to category 7 and reprogram.
4. Make sure all unused wires are isolated separately.
5. After all commands are verified to work properly, secure the SWI interface so that tension will not pull either of the connectors loose or apart.
6. That's it! Enjoy!

Thanks so much for the info Jeff. Do I need to buy resistors for this installation or do they come with the kit?
Once again thanks,
Willie

It's included with the kit.

47ohm is (yel/vio/blk)
150 ohm is (brn/grn/brn)

Thanks alot Jeff. I was wondering about this too. Unfortunately, the place I ordered the ddx814 was on back order so i had to get the ddx714. So to cut a long story short I have all the parts except for the head unit.

anyone have a picture of what this step should look like?

3. Connecting the SWI-JACK 's steering wheel control input wire to vehicle plug.
Connect the SWI-JACK 's White wire to PIN 16 (Blue) with a 150 ohm resistor, PIN 15 (Pink) with a 47 ohm resistor
Connect free ends of resistors to interface's White wire.
Ground the BROWN wire found in the same radio connector.

Hey Jeff i was doing this part of my install with the ddx714 i got and i do not see a pink wire. The wire next to the blue one is blue and white....

my pin 16 is blue and my pin 15 is black

The wire colors may vary but the pin locations are correct!

A bit hard to read in this format. Here's the link for those interested, hope Jeff doesn't mind.

Steering Wheel Interface Vehicle Instruction Guide

Hey 510z... i was looking at the manual and the one wire says its is a ground did you hook this up yet? If so did it work out for you? I also get the same thing as you that they are blue and black.... however one is pink in slot 6 which is also a steering wheel wire as the service manual indicates. Any feed back would be helpful

“Z” Pin #6 to 47ohm (yel/vio/blk) to PAC white wire
“Z” Pin #16 to 150 ohm (brn/grn/brn) to PAC white wire
ground pin #15 (Br)
PAC black wire to “Z” ground

Thanks so much Conch... I was thinking that would make more sense but i wasn't sure.

I was just working on putting in the SWI-PS and this thread came in handy. Here is the plug diagram so you know what # wire is which..

Exactly what I was looking for-
Thanks!

Darn I never saw them when I went to install one.:shakes head: :eek:

Those who got it to work... did you cut the brown loop on the SWI or not? There's a conflict between the info at the top of this thread (which says to cut the loop), and the instructions at Pac-audio's web site (says not to cut the loop).

I wasn't able to get mine to work. I did NOT cut the brown loop. I'm about to go back out to the garage and check my wiring. If everything else looks good, all I can think of is to cut the loop and see if it works.

Do not cut from what I have understood.

Thanks. I got it to work. Do not cut the brown loop.

For anyone who attempted this and it didn't work, I discovered that the instructions at the top of this thread are slightly off, as were the instructions on the manufacturer's web site as of last week. As of now, they've corrected them and they worked (for me).

I thought I was loosing my mind when I read the manufacturer's instructions at their web site this morning and they were different than what I remembered reading last week. Luckily I'd printed them out last week and they are definately different. I'm not insane.

Ok, maybe a little. :icon14:

so the blue/yellow wire.. the instructions on pac-audio's website dont say what to do with that.. does that get hooked up to the blue/yellow wire on the kenwood plug or not?

unless the instructions on your pac states to use otherwise, just leave it taped up. i think there were only 3 wires on my setup that i used... and 2 resistors.

and left the loop as is.

actually I did find where in the instructions you have to connect that wire.. if you dont there's nothing that tells the headunit what buttons you are pressing.. also the printed instructions say that is specifically the Kenwood remote control wire.

now a different problem..

after hooking it up and programming it..when i press track up, it raises the volume, and "source" lowers the volume... volume up/down buttons work fine, as does track down..
i've got everything connected correctly and cleared/programmed that thing 5 times now... idk what the deal is..

btw i'm using pac swi-jack and kenwood dnx6140

any ideas?

FIgured it out... I had the wires from pin 6 and pin 16 in the factory harness touching before the resistors..
Since the resistors both go to the white wire of the pac adaptor after the resistor i didnt think it mattered, apparently it does..

This sticky is great and really caught my attention as a new head unit is high on the upgrade list for me.

I just wanted to add something basic to this post for newbs like me. It's probably common knowledge to some advanced users but I never installed this type of thing so I wasn't well informed on it.

Not having used any PAC products before I thought SWI-"JACK" was their only steering control module or generic term. That's all everyone was talking about here. So I started searching the forums to see if it would work with the Pioneer I was looking at. After some searching here and on Crutchfield I found it's not compatible :mad:. SWI-JACK works for JVC, Alpine, Clarion, Kenwood. What I didn't realize until recently was they make other modules for other stereos lol. Link is here:
Pac-audio.com Products | iPod Integration for your car and More by Pac-Audio - Connecting you to the future

SWI-JACK = JVC, Alpine, Clarion, Kenwood Radios
SWI-ECL2 = Eclipse Radios
SWI-PS = Pioneer, Sony (& according to Crutchfield Jenson) Radios

There's a universal and some others there too.

Link to my original post about it to consolidate the info:
http://www.the370z.com/audio-video/1...l-pioneer.html

Are the delays from the steering wheel input controls still an issue? I am seeing lot of people having this issue.

I would think someone could make a custom module relatively cheap as long as we know the following:

1) output current/voltage for each signal (370z base model: source, select up, select down, volume up and volume down)
2) number of input signals, input current/voltage and input signal combination(corresponding to each function) for each manufacturer

a simple circuit to accommodate above signals should be relatively easy and very responsive.

this is based on my assumption. please correct me if am wrong. i would be delighted to see something other than PAC-SWI used on the 370z. if the darn things doesn't work right then we shouldn't use it at all. i just would like to have something that i allows me to use the existing SW controls without all the nuances.

i found additional information from a different forum that may help those of us who's looking for a better solution than SWI-JACK. It'd be some work but those of us who's familiar with electronics should be able to implement this.

update:
found additional info on building your own SWI with no delays.

I have a dumb question. Everyone keeps talking about connecting the resistors at pin "such-and-such", but my question is, how do you connect them? Are you tapping them into the factory wires or are you inserting them through the empty Scosche holes into the factory harness? I haven't been able to find any specific instructions, just general "connect here".

yes that is the same question i was going to ask :p how do you connect it?

^^ solder then shrink wrap

^^ using additional wire between the desired connection

Helllllpppp!!!
 

OK guys, I think I screwed up on the SWI-JACK. I've got all of the resistors connected, etc. My question is on the other end of the unit. I hooked the blue/yellow wire on the SWI-JACK to the blue/yellow wire on my DNX8120. Where does the black wire with the plug go? Did I do a major screwup by cutting the "plug" off of my DNX8120?

I'm in dire need of help because I was planning on installing this on the weekend.

Thanks.

Whew! I think I found my answer to the above. I guess I didn't screw up, I just don't need to use the mini-jack.

Feel free to tell me if I'm wrong. Everybody else does. :p

PM sent as you sent one

Okay stupid question. When installing the SWI-JACK or SWI-PS are you cutting the wires going into the factory male plug that connects to the OEM head unit (via a female receptacle), or does the SWI-* unit provide a female plug with wires that you then cut? I'd prefer not to cut the factory wiring harness, and would like to simply extend the wiring with another plug in the middle.

question about metra Axxess interface...

I dont get how to connect the wires in the below steps...and when it states connector in the vehicle does that mean the harness? or the HU?

3) Connect the Gray/Red wire of the ASWC to pin 6 of the vehicle. Below is a picture of what the connector in the vehicle looks like:
This is the pin view of the connector in the vehicle
4) Connect the Gray/Blue wire of the ASWC to pin 16 of the vehicle.
5) Connect pin 15 of the vehicles harness to Ground.

Thanks,
Jay

Thanks for the diagram. I noticed the harness for my Pioneer AVIC-X920BT has a speed signal wire. I assume for those ECCO functions. Can I tap pin 18 marked speed on the factory plug for that?

Yes it's the factory plug to the stock radio, not the one you buy to marry to the new head unit harness. You can cut it if you want otherwise you just need to tap into it. Cutting is not neccessary though. No extra plug/harness provided by PAC but you can get 2,3,4 ect pin harness with a loop of wiring you can cut to lenth and electronic supply stores. I got one for $2.

This wiring would not work for me. I had to wire it with these pins according to Conch's post

“Z” Pin #6 to 47ohm (yel/vio/blk) to PAC white wire
“Z” Pin #16 to 150 ohm (brn/grn/brn) to PAC white wire
ground pin #15 (Br)
PAC black wire to “Z” ground

Is the only way to connect the resistors is to solder them? It's the only step I have left, but wanted to make sure I do it right...

You don't have to. It actually will work fine with a standard 2 side crimp. Just put them both in and crimp it well making sure they wont slide out. Also make sure the side of the resistors that are not connected do not touch each other.

That's actually just what I did. Easy install and works great. No delay at all as others have mentioned. Only problem is no matter what I do my preset channels don't work. It will only seek. Not that big of a deal I suppose. But, would've been nice. It does say that presets may not work with certain models. I guess I have one of those models.

I installed the PAC SWI-PS by the way.

I have a quick question... With the newest PAC-SWI-JACK instructions for Nissan 370z Radio (Base model I suppose) on iPod Integration for your car and More by Pac-Audio - Connecting you to the future, they don't mention about connecting the “Z” Pin #6 to 47ohm (yel/vio/blk) to PAC white wire. All they say is Connect pin6 in the vehicle connector to interface's white wire. So my question is that do I need to connect the 47ohm resistor as described in the old manuals? Thanks.
