I'm having issues with the turn signal wiring. On the wiring diagram it has left turn signal head lamp being light green and white wire. For the right I thought it was light blue and white wiring. That has proven to be incorrect as it causes my hazards to come on. And the rear tail lights stay lit up. I was told that it was light brown and white instead but unfortunately I don't see a LB/W wire by the gauge cluster set. I a harness from an 03 Mach 1 and ecu. This is the biggest thing that is holding me up at this point.

do you have the GEM module plugged in?to verify, you are trying to repin an 03 headlight plug, to a fox connector correct?

I am trying to repin the 03 headlight to the fox connector. GEM module? I'm not that familiar with a lot of this stuff.

the first pic is the back of the headlight plug repinned with 03 wiring..the green/white, blue/white, and grey do not go to the headlight plug. they go to the dimmer switch..wire up the dimmer switch as follows...grey from 03 harness go to green/yellow on dimmer plug. green /white stripe on 03 go to light blue/blk on dimmer plug. blue/white stripe go to light blue/red on dimmer plug. there should also be two brown wires coming out of the dimmer plug , run those to the parking light wire like i did in the first pic.. and make sure your hazard switch is plugged in to test. good luck

What about the wires that are coming out of the gauge cluster harness? This pics are great by the way.

What did you tap into for the turn signals? The reason I ask I'm missing that part of the harness and all I have is a small stub of wires.

I'm missing the harness that connects to the gauge cluster. It looks like that part was cut out. And i'm using speed hut gauges so I have to wire everything manually.

i used a complete 03 cobra harness and guages..what part are you missing on you harness
Can you post more pics on how you got the fox headlamp switch to work with the cobra wire harness. I have all 96' wiring in my notch and I can't figure out how to wire fox switch and dimmer. For the head lights I just used the sn95 connector and used a dremel to knock off some tabs and it fit right into fox headlight.

After reviewing all the diagrams, the only thing left to test is the multifunction switch. The wiper motor is not working, so that is leading me to believe that it may be the switch itself. The turn signals in theory should be working automatically since it is connected directly to the 03 harness with the 03 multi switch. Unless the person that sold me the switch sold me a bad one. So I will have a new one coming shortly to test it out. I hope that's my issue. Currently the turn signals don't work at all. I have the front lights on with the exception of one of the markers.

O.k. I have checked all the wiring and I can't find anything wrong. What could be causing the turn signals and wiper motor not to be working. Is there a specific ground that I should of connected? I checked the fuses and don't see anything wrong. This is driving me nuts.

the dash harness has two grounds??? run a jumper wire from the batt ground to the wper motor body make sure its grounded, if it works, then ground is the issue..all the fuses good?
It only has the one ground that I'm aware of. I'll try and jump it like you mentioned. And the fuses are good all these fuses are the ones under the driver side correct?

Guys I'm completely stuck on this now. I received the new multifunction switch today as well as a new flasher module and nothing. The wiper motor doesn't work as neither does the turn signals. I can't find a bad ground if there is one. If I can't figure it out I might just have to take it to a shop that can figure this out for me.
