factory fog light wiring

[Krusher 5.0]

I got an 85 Capri, it has the factory fog light switch under the dash. I put some aftermarket lights on it but couldn't find the factory wires to hook them to. Can anyone tell me where they might be and how many wires & colors? The circuit is at least working. With fog light switch on and lights on dim, the LED lights up and you hear the relay click. I just need to find the wires under the hood.

Yours is the one that someone aero nosed correct? The original fog light bar had a harness that ran across it, and it plugged into the car up in the fenderwell area somewhere, but not sure where. Maybe someone just unplugged your harness when they did the nose? I don't have anything in my car and am getting ready to wire it from scratch so I would like to know how this works too.

Here is how it is on my '86:



This is the fog light harness that clips into the bar that the fog lights themselves bolt into.
The plug on the far right plugs into the light harness on the drivers side somewhere below the headlight and side marker from what I can remember. The colours for the fogs on mine are brown with orange stripe +12V and and black -ve.

Harness plug


Fog light plug


Plug from light wiring harness.


This feeds in an opening around the DS headlight and drops down to the fog light harness. The wiring for the windshield washer etc. goes down the same way, In front of my battery. Might be different on both yours' as the battery is on the other side on your car. But I think the colours will be the same on Krushers. Trav, are you adding after markets, or donor fogs?
Hope this helps a little.

I have an 84 with a build date of 12/83 and it has half the 84 1/2 stuff on it, and it has that plug! Just no switch or relay. Can't remember what side it was on, I had my entire harness ripped out. I'm using all factory parts on mine, I want it to look like a true 84 1/2.

I found the wires. they were on the passenger side but no plug cause someone had butt connected a rubber side marker light socket to the fog wires. I just hooked into those 2 wires (black & a lighter color that may be faded orange). they work like they are supposed to, on when headlights are dimmed & off when bright!
