Fog light wiring

Like it was mentioned before, find the harness to the headlamps, follow it to the ground bolt, if the fog wires are there, they are tapped to the bumper in that vicinity.


Also, check that the missing relay slot in the engine fuse box has the receiving female terminals.

 

If you have the plug for the switch then you are prewired. I was in the same boat. My wires for the fog lights were zip tied up to the left and right of the crash bar, if you look from the bottom of the truck and up towards the back of where the fogs would be you should see it hanging around that general area. Then you’ll just need to get the blue relay and good to go

 

If you bought the fogs as a kit, this is the install instructions.

Although I don't think you did, the instructions may still help you ferret everything out.

 

Thanks all. I’ve searched through the truck and the wires are just not there. Nor is the female connector in the engine fuse box. Not sure why the dash wiring would still be there, and illuminating the switch, if the rest are not. Very odd. I guess I’ll have to buy and install an off market system.

 

In my 07 I had fog lights but the button on the dash did not illuminate. I also had wiring for the power in the bed traction control and whatever else. I believe they may just use the same wire harness for all the trucks and just not install the other components to the system. I had an SR5 so I didnt have any fancy stuff but the wires behind the dash for the switches were there

 

Maybe the slot is in the auxiliary box (smaller) next to the main engine fuse box. I can't recall when they changed the location of the relay.

 

if you have the base model truck 99.9% they aren't pre wired for foglights
