How To Make Your Own Wiring Harness For Fog Lights

[Mr.Bergner]

Sorry I didn't think about posting a pic on how I wired it up.

I basically trimmed the wire down and shoved it behind the harness next to the wire that goes to 83b. Usually I'd dab some hot glue there to hold it down but since I didn't have any I put a few pieces of electrical tape to hold it down, then secured it all with zip ties so it doesn't come loose. It's worked fine since then.



Probably the better way to do it is to use a splicer.

Ok thanks alot guys. Ill have to look at it again this weekend. All the other wiring has been completed though.

Another question. How important is it that you use 14 gauge wire? I used it for most of my wiring but ran out and used some other wire I had laying around, and its not 14.

Hi. I have fitted the OEM switch with the fog light position and the spots are already fitted in the bumper. A replacement bumper was fitted after the old one hit a bollard. However, there is no harness to connect the fogs.
The connector on the light switch does have the Green/Yellow wire that supplies power for the fog lights.

According to the Haynes manual, this wire splits into two green/white wires, one running to each fog light. This implies that I can splice into this wire on the back of the switch and feed directly to the spot lights without adding any other relay or fuse. Is that correct?
Secondly, Where does that wire from the light switch go? If it runs to somewhere in the engine bay, It would be much easier for me to join into it there than to try and run a wire from inside the car. If I do have to route it from the car I cannot see any obvious grommets or holes I can run it through in the drivers footwell.
Any help or advise would be greatly appreciated.

OR you can do what I did.
I had a member on here make me a 2wire harness.

I used the middle wire of the grille lights as my soruce.
I cut the wire and ran light off of that. I cut the ground wire in two and spliced the turn signal and fog lights back it.

its been working for alomost a year now.. and NO it doesnt blink

So your fogs are powered from the grill lights?

How do the fogs operate exactly?

Sorry for all the questions but this is pitiful lol, I've had my fogs for almost a year and they still don't work.

I didn't look back on all your posts regarding your fogs, but the main reason it's not working is your switch right? That one pic you posted has the wire shooting out of the OEM plug.

Im honestly not sure what it is.

I have it wired up according to the wiring diagram in the OP.

The wire sticking in the harness didn't fit because of the plastic insulation on the end of female pin connector I have on there.

But what I did was drill that part of the harness to make the hole bigger so the female plug would fit inside it and the harness could plug all the way into the switch. Once it was plugged all the way in I double checked to make sure the female connector was snug on pin 83b and plugged it all the way in. But no fogs, headlights and everything worked as normal though.
