Hazard Switch Wiring Diagram

ProfessorDave

I guess this is my week for wiring questions . I'm looking for the wiring diagram for the hazard switch. There are 4 prongs on the switch. The middle two are power in/power out (not sure which is which). I'm guessing the other two are illumination and ground. Anyone know the official function of each of these prongs?

Thanks!

Update: I downloaded the service manual, which only identifies the 2 middle prongs as 1=ground and 2=BCM (for manual transmission).

Edit: Service manual is wrong. Correct order:
1st lead = grd
2nd lead = power out
3rd lead = power in (BCM)
4th lead = illumination of switch

Is this the same for the s mode button? I want to make the s mode button light up by splicing the wire from the hazard button to the s mode button. All I would have to do is use the 4th prong correct?

I meant 4th lead not prong. Sorry!

professordave- wat are you trying to do again?

ProfessorDave

I'm not sure, but I was reminded earlier that the S mode switch is momentary, so it wouldn't work for my application.
I used a second hazard switch to wire up the solid on function of my EVO-R rear fog. Check out my DIY (AK stickied it for me). I had considered using a heated seat switch, but decided against it due to aesthetics.

Hi ProfessorDave,

I am trying to do something similar.... I purchased a s-mode switch to use with my nav's voice activation switch....

The sport mode switch also has 4 pins....... my voice activation switch of the nav has 2 wires.... its a Kenwood 9960.

Any suggestions?


Thanks,
Jay

I accidentally yanked the wires out of my 4 pin hazard switch connector when installing my stereo, anyone know the part number for the connectors?

Nissan wants $150+ labor to replace wtf??

I just need the 4pin connector from the harness so i can do it myself. I found another place that will match the connector with 6" leads so i can splice it but they want $135 wtf??

Actually that was a typo, Nissan wanted $1500 to fix it!!!!!!!!

Apparently this is part of the body wiring harness and it requires the entire thing to be replaced. Total ********, it's just a plastic molex connector with 4 wires, I'd NEVER let them tear my car part and replace a body harness for that. It's insulting that they even recommend or expect that to be a logical and viable repair.

I found a place that will send you the connector with 6inch leads and you just splice it in. They want $135...but that's my option...unless someone lse knows where I can find it cheaper?

Word to the wise, be very careful when removing the console.

Which way does 1-4 run? Colors help too.

The FSM should have that info. There is usually a section after the wiring diagrams that gives connector pinouts and wire colors. If ProfessorDave is right abut the FSM not showing the pins/leads correctly, you will have to match function to color.

I see none of that. Been through the whole manual. That's not how this manual does it. Even saw a few others that aren't really cut and dry. One wire color doesn't help either.

For some reason that I can't figure out, Nissan decided to delete the pinouts from the 2013 FSM. They are in the 2009 FSM on page EXL-85.

The A7 uses connector M144 and the M6 uses connector M256. Same style connectors but the wire colors are different. On M144, the ground wire is GR and the wire to the BCM is P. On M256, ground is B and the wire to the BCM is P. I think GR = green, B = black, and P = purple, but I'm not sure. Color code is in the GI section.
Looking at the connectors from the harness side (the "backside" of the connector; where the wires enter the connector), the terminals are labeled, from left to right, 3-1-2-4. Ground is on terminal 1 and wire to BCM is on terminal 2.

Edit: Had connector names for transmissions reversed. Fixed.

Here's my 13...I have a M6



The white is the hazards. So looks like on my new switch ill put (from left to right) the 3rd black wire to ground, the 2nd/green to 12v?? Is power the BCM terminals? Looks like it from the manual since the battery has a wire feeding the BCM. Any idea on which is the LED when you turn the head lights on the button lights up? Will the 4th wire just get deleted since the new switch won't be able to blink or something when you turn them on?

Now what about he synco?

Just checked the main wire harness if it matters, they are all different colors. The pig tail that the white and grey plugs go to one main plug that plugs into the main harness the colors are as follows

Grey plug/synco

Black w/ yellow stripe goes to solid black on main harness
Black w/ red stripe goes to solid black
Green w/ white stripe goes to solid green
Dark blue with silver spots goes to solid dark blue

White plug/hazards

Orange goes to a thick solid black wire (only wire bigger than the others)
Green goes to solid black
Black with silver spots goes to solid silver
Light blue goes to solid red
