I found my fog exterior light wiring under the front bumper. It plugs into the factory fog lights. On my '96 Ram, there is a separate switch that sits next to the overdrive switch on the dash. I was able to find the fog light switch for that style truck off another truck at a local pick and pay yard. I'm hoping to find the interior fog light wiring once I pull the dash apart later this year.

 

PDC? Sorry for not knowing what this means? I know the fuse box under the hood has a relay slot that is for fog lights but that's about it. Nothing else.

 

It's the large black box under the hood with the relays and fuses in it - PDC = Power Distribution Center

 

Ok, I never knew the name. I just called it the main fuse panel/box. Thanks

 

Same here - I had to Google that one. I didn't work at a dealership like some folks, so I'm somewhat acronym deficient...

 

Did u find the foglight switch harness i own a 96 my truck is wired for it got the bumper harness for the foglights under hood fuse block 15amp fuse and both fog light relays i ordered a 96 ram foglight switch thats next to the overdrive button on dash but for the life of me cant figure out where the harness is for the factory foglight button

 

To-date, I haven't found it. It could certainly be there in a hidden place, just as the blue connector for the brake controller was hidden well. When I dis-assemble my dash to rebuild it, I plan to look for it again.
