Installed Lights behind Grill
No plans for a trip to MD, but on your next road trip to Cali, swing by the house and we'll put them in, lol
I'm interested in anybody has done this with A/C

To get the lights to operate as stock (only on w/ low beam), I connected Pin 86 on the relay to the WH/BK wire on the light switch, and Pin 85 on the relay to the yellow wire on the switch. I consulted the wiring diagram for my ‘99 for this setup, and I believe it is correct for ‘97-‘99 (if it’s not, someone please correct me ... I’m pretty much a novice when it comes to anything electrical). I think the ‘00+ are wired differently. On a side note, the light switches for the ‘97-‘99 are different than the ones for the ‘00-‘03, although they look very similiar in the cab.
They work!!

They work!!

Edit: I just looked at the back of my headlight switch and I didn't see a white w/black wire there that only activated with the foglight switch engaged, If you can take a pic of the back of the switch so I can see what wires you are talking about so I can do this I would be GREATLY appreciative.

First, keep in mind I'm REAL weak when it comes to electrical. I've now run the lights for several months w/ no issues, so I'm assuming my connections are OK.
From the wiring diagram posted below, it appears the yellow is for the switch w/ the white/black for the ground. The note that reads "directs power to energize fog lamp relay" is what led me to connect the white/black wire the way I did.

The white/black wire comes from the small gray plug on the right
I hope this helps you out. It amazes me how much I'll forget about how I did something just a few months earlier ...

Looks like the two big plugs to the left look the same as mine but the little grey one to the right is missing some wires compared to mine. I will get a pic in a min what features does your truck have? I know you did fogs yourself but do you have DRLs or Autolamps?
Edit: Here is the pic I just got of the back with the wires

From what I can see the wires are as follows: (Looking down at back of plugs after pulling from dash and bending light switch to face floor)

Ace_boy2099, my truck is a XL (base model), so it wasn't equipped w/ autolamps (or much else for that matter ...
). The white w/ black stripe wire I connected to is on the right side of the small plug on the right in your picture (it's actually two wires). The yellow wire is in the larger black connector in the center of your pic.

Thanks Fairlaner, I just did this in my truck and they work. Now I am just waiting for the HIDs to come so I can use them. When I take the switch apart to change the light in it (trying to go to blue eventually) I plan on doing the mod to make the fogs work in all modes.
