Where to tap into for B.U. Cam, power, etc?
 

I've been searching the forum for a couple of days. I can't find the thread I saw once. It had pictures of a fuse box and had labels. Does anyone have links to where to wire your harness for B.U. cam, power, ground, etc.
Car is 2010 nismo, harness is Metra 70-7552 , H.U. is Kenwood 9960
thanks

I've got a 9960 also with the Kenwood CMOS300. I ran the green reverse wire to the back of the car and connected to the backup light wire.

As far as power, I connected within the center console (between the seats) to accessory power.
Many guys have run the power to the backup light line, but the problem with that is that only time you can turn the camera on is when you are in reverse. The 9960 has the ability to view the camera by hitting "AUD" button at the bottom of the HU. By using the accessory power, you basically have two switches to view the camera. 1. The AUD button or 2. putting the car in reverse.

I used the power that goes to the "cigarette lighter" (or whatever it's called) that is under the lid on the armrest.

I think the document you want is:

For the reverse wire I think maybe this one http://www.the370z.com/audio-video/2...t=Reverse+wire

Yes, those are good directions to the reverse wire. For me, the bundle of wires that was closer to the rear of the car (when you untape the big bundle and find 2 smaller bundles inside) held the orangish~tannish wire. I tested by attaching my voltmeter probe to an exacto knife then carefully piercing thru the insulation to test. 0V when not in reverse, 12v when in reverse.

Good info for the reverse light wire. thanks. I'll hook it up to the one in the front of the car. Any one have info were to hook up the speed sense wire and the VCC wire? or if they should be hooked up. I want to be able to play a DVD while the car is in motion for the passenger. H.U. is a Kenwood 9960

Again, check out the links in the previous post I made. They have all the info you are looking for....

When i was installling the Navtool and Cam a few weeks ago i snapped this picture after my frusteration of testing every Orange wire. I found the reverse wire was infact not orange but more tan.

There is a lot of confusion in those links Whee. It seems that post is for 370's with Nav Units and for G37's. It does show the connectors for those cars. Mine is a 2010 Nismo. I'm looking for the best place to tap into the harness or connector for the VSS and Parking Brake wires for my car.

I am not 100% sure about the Nismo, but the wiring harness in the dash should be the same for each model regardless of which A/V head you have. It would make sense from a manufacturing point of view. It is easy enough to disassemble and check.... all the wires you need are in the back of the A/V Head under your cubby hole.

All info below taken from this thread: http://www.the370z.com/audio-video/1...ck-2010-a.html

The VSS is pin 82, beside it to the right in bright orange is Pin 81 for reverse signal, and then in green to the right is Pin 80 for Ignition power. Pin 65 below them is your ebrake to ground out so you can watch DVD's while moving.

Thanks, Weee. How many switches do I need, 3? One for the vcc wire (speed sensor) to just break the connection to he H.U. to make the HU think its parked. One for the parking brake sensor to ground it and make the HU think the parking brake is on. And one to supply 12v to the reverse sensing wire. Any tips or shortcuts you guys have will be appreciated.

Go to the link in my previous post for the Plug and Play ByPass kit. The last couple of posts I listed the build items. You will need an OEM seat heater switch to make it all pretty though!
Switch forward for NAV Bypass (through a relay) and then backward for backup cam on whenever. Ground the DVD brake sense wire permanently as it has no other use.

I went to the previous post. I noticed that you need to wire a relay and make a little harness. I havn't done this type of work but if there was documentation to follow I'm sure I could do it. Are you making a kit?

I didn't use any relay to hook my camera up. Hooked up the power leads to accessory power and the reverse wire (purple) to the backup light wire and connected the appropriate wires to the HU.

The relay is only there to OPEN the connection when power is applied to cut off the VSS Switch. Nothing to do with the camera

Since I have a DNX9960 I'll use the AUD button on the HU to use the camera while the vehicle is in motion. I will ground the parking brake sense wire. Then all I have left to do is to put a switch between the HU and the VCC wire. Do I still need a relay and seat heat switch?

No, then you can use any single pole rocker switch that is normally on, and switch to off. Or a ON-ON switch would work as well. Easy enough to find. BUT if you want the switch to match the interior of the car, you are limited to the seat heater switch. Maybe you can find another use for the other position such as turning on the rear fog lamp (future upgrade) or Radar Detector mute... just thoughts.

This is an aftermarket automotive switch that would also work but not be as elegant as the seat heater switch. painted this one flat black after I took the pictures and it matched better. I just decided to go with the seat heater switch in the end for complete functionality.

I did not insert the switch fully so that i would not do any damage to the finish on the console.

Standard ON-ON switch

Gloss black rocker. Needs to painted flat black to match better.

If I go with the seat heat switch will I need to use a relay?

yes because the seat heater switch engages 12v to the pins when the switch is activated. You need to use a relay to BREAK the connection to the VSS

If I go with the rocker switch then no relay is required?

Correct. It is an unpowered switch from on to on, or off to on.

OK, I'm trying to get a handle on what I have to do before I start my install. The vehicle is a 2010 nismo. H.U. is Kenwood DNX 9960 I've been studying all links in the forum and I'm still not clear. The photos in the links are not matching up to my harness and adapter. My adapter has 20 pins. It's a Metra 70-7552. I'm thinking since the adapter plugs into the cars connector it will be touching the VSS wire. Which wire on the adapter will be the VSS wire? This is where I'll wire the switch to. Can anyone tell me which wire is the VSS wire on a 2010 nismo? I attached photos of my harness and adapter. thanks

hmmm.... that harness does NOT look like it is compatible with a 2010 Z

I just installed my camera using the nav tool hookup ( i have the nav system). as far as the power I used the lighter that is located in my armrest. Once you have the center off you will see the wires I am talking about (orange one I believe) I just spliced into that for power and grounded the rest of the wires on a bolt anywhere on the car. as far and the reverse light I just used the same power wire off of the ligher to have the camera come on anytime I flip the switch that is attached to the nav tool. when you are going down the road you can see and it looks like you are going like a bat out of hell especially at night. If you pm me i could probably go out and take a few pics of this install.

Nav Tool is incompatible with the 2010 or higher models...

I thought they fixed that, either way I was just trying to relay where I got power from not so much promoting Nav tool.

No problem. The OP is avoiding the path of tapping into the factory harness behind the centre dash AV unit. Once he realizes there is no easier solution, my guess is he will follow the multiple previous posts telling him exactly what to do....
:facepalm:

Yes, I am trying not to cut into the factory harness. I'm just looking for a picture of a 2010 nismo connector and someone pointing out which is the VSS wire on a 2010 nismo connector. No link has shown this. The previous posts and links were for G37 and other year and model Z's. I'm trying to know what to expect when I pop that connector off. I tend not to believe the catch phrase "it should be the same......i think" The adapter was sold by Avenue Sound where I bought the HU from. They said that is the correct adapter. I also checked this link to make sure as best I could that it is the correct adapter. Metra Online | Welcome to Metra Auto Parts Online Warehouse It's a 20 pin adapter and none of the links showed a 20 pin connector. I will take pictures of my install and post them to try to make it easier for the next guy.

Sounds like to be certain, you will have to look for yourself. You have the base stereo, right? Then it is 99.9% certain you will find this connector:

Looking at your Metra adapter, it does not have a wire for VSS, but you MIGHT be able to pull out a rear speaker pin/wire and reinsert it for the VSS connection. I started a thread on how to move pins in the Scosche adapter, but have no experience with the Metra.

The 'consensus' opinion of the forum was to hack into the vehicle harness (for reverse and steering wheel remote wires in my case; no nav), but relocating pins in the Scosche adapter eliminates the need to do so. You may very well find the same can be true for the Metra adapter. Go for it!

^^^ good info. Crack the dash and have a look. You will need to do this at least once anyways, practice can't hurt!

I should amend my post: I DID still have to hack into the vehicle harness for reverse lights connection, since that is NOT present in the OEM radio connector. I expect you will have to do the same.

Thanks Turbodog! That's what I needed. Where did you find that? I'm going do like you suggested: slide out one of the rear speaker pins and re insert it to connect to the VSS. I have a few questions. Which wire does the VSS connect to on the Kenwood harness? and on the ASWC which wires would go to STRG SW A and STRG SW B?

Well, if you looked at the diagram turbodog posted, you could clearly see pin 18, yellow is the correct wire for VSS, pin 6, pink, is STRG A and pin 16, Lime?, is STRG B. Do you not have a photo or manual with the ASWH?
Seriously. Can you not read the illustration?

I asked which wire does the VSS wire connect to on the Kenwood Harness. I was thinking that the VSS wire connects to the HU's wire harness. I figured this is how the HU knows the vehicle is moving. So if someone knows thats great, let me know. None of the labels on the Kenwood harness say VSS or anything to do with vehicle movement or speed. I can read the illustration. (if I was at home) When I got home I did look at the ASWH illustration. Weeee is correct, exept pin 16 is blue not lime.
thanks.

Well, when you have finally wired this up, make sure you document and photograph it for the DIY you are going to write!
Good Luck! Keep us posted!

I just downloaded the Kenwood installation manual :
http://kenwoodusa.com/UserFiles/File...60_Install.pdf

It does not mention a VSS connection. Probably why you don't see a wire to connect to. It uses the parking brake switch wire to determine if the car is in motion for safety regulation compliance.

Thanks again Turbodog. If thats the case then I don't need a switch at all. All I need to do is permanently ground the Parking Brake wire. Now I need to find out for sure if that is truly the case.

You really need to read the install and owners manuals. My Pioneer requires the parking brake to go on-off-on before it will enable video. Simply grounding the parking brake wire would not have worked for me.

Yes I agree. That is exactly why I said; Now I need to find out for sure if that is truly the case. I'll post what I find out.
