Hazard Switch Wiring Diagram

synolimit

To simplify this I'm no long going to talk about the pig tail...just the main wire harness as seen in the picture.

Just for reference though, pig tail colors to main harness

Orange to main is thick black- ground
Lt blue to main is red- LED in OEM button turns on when headlights turn on
Black to main is grey- ground
Green to main is pink- when this wire is grounded at any time (car on or off) the hazards come on.

Ok, pink and grey go together and the hazards work but no LED. Black and red go together and I get the bright LED but no hazards. I take it this is it? I either get a LED or I get the hazards which of course I want.

Any other configuration I do, I either get a dim LED or a bright LED except if I do pink and red together I get hazards but again no LED.

Yep. With that switch, you can't have your cake and eat it too.

The problem is that you are working with a sinking circuit and most switch/light combos are meant to switch power to a device. That's why Nissan used a four terminal switch/light.

Lol gotcha. And FYI I have to do grey and pink to prongs 2 and 3. Using the actually ground prong for the switch (number 1) doesn't work. Now off to do the s-mode. I'm thinking using 2 and 3 again and the middle two wires will do it, I hope.

I don't remember looking at the S-Mode circuit, but if it's another sinking input then wire it the same as the flasher. The S-Mode switch may be momentary contact instead of the NO switch you are using.

That's what I'm thinking since the OEM switch is press quick to turn on, and press and hold for a few seconds to turn off...

**** I know it is. The OEM hazard looses height when you press it down till you press it again. The s-mode stays same height no matter what. Looks like I need to swap that switch. And looking online those only have 2 prong switches.

Well everything's done and everything works. Except one thing. Notice the stereo and heat controls don't light up. Kinda odd since the grounds I didn't use only went to a switch and not to a grounded source. I'm thinking the orange to thick black wire on the main harness needs a new ground home. For both the hazards and s-mode I only used the two middle wires on the pig tail harness.

Edit. Actually it probably is the thick black wire. After finishing the hazard switch I hooked the s-mode back up as stock. I noticed then the s-mode didn't light up. So that means that thick black wire must have been grounding both switches illum lights and these other lights some how.

I'm glad to hear you got it working.

It may be a ground problem but could be the illum power circuit. Check the wiring diagram and see if the stereo/heat lights have a common supply or common ground with the flasher/S-mode lights. If they don't have anything in common, then you may have knocked a connector loose.

Wasn't the large black to a ground. O well, I've lost a few lights.

This should be an easy fix. I think when you cut the wires you cut one (or two) that was feeding (and/or grounding) the other lights. I'll take a look at the schematics later. Have an appt at the dealer in a few minutes; I'll try to remember to look it up when I get back.

I found the lights in the INL section of the FSM but the schematic doesn't give a clear indication of how it's physically wired without digging through pinouts and such. I think you broke the circuit to the lights that are out when you did your rewiring but can't eliminate a loose connector.

Reconnect the wires that you didn't use. Connect the ground wires to ground and the illum power wires to an illum power point.

Well I fixed it...I hope!

Turns out my tail lights were out too! I still had turn signals, brake lights, and back up lights which I tested looking through my rear view on a house but my tail lights that turn on with my head lights and my license plate lights were out that I just noticed

I knew it had to be a fuse then. Thankfully it was. I'm hoping all wires I've pulled are still taped up properly and it must have been when I was testing hazard wires that something touched and blew the fuse. Kind of a bitch to get to but it was here by the battery marked 10a tail/illumi
