Question on DRL module and foglights

[Tbruz]

Trying to get the OEM foglights working on a 1997 Tahoe using stock parts adn harnesses.
Schematics show a feed from the DRL module (daytime running lights modue) to the fog light switch.
Two questions:
1) Is a DRL from a 1999 or a 1998(years the fogs were offered by GM) the same as a 1997( fogs not offered from GM that year)

2) Where physically is the DRL module in a 1997?

Thanks in advance
Tony

should be identical and look on the main harness for a grey plastic ase and pop the cover. the module board is inside.

I thought the fog lights came on the 99 and 2000 Tahoe limited and Z71. I personally haven't seen them on prior years, but I know on mine they are wired together with the day time running lights. Try looking at the 2000 obs Tahoe or Denali for wiring for the fog lights.

I have a '96 and the provisioning for fog lights is on my vehicle.

As far as I've been able to figure out, the in-bumper fog light option came only on 1999 or 2000 limited or Z71 packages.

That being said you only need the bumper, lights, mounting buckets, underhood harness, under dash harness, fog light switch and appropriate filler plate for the foglight switch(either in the horizontal 4 x 4 slot or in the vertical 3-slot plate) to add this factory option to any OBS style Tahoe.
All the parts except for the mounting buckets are readily available.
I have p/ns if anyone is interested.

The underhood harness is simple, 1 connection to each of the foglights, one ground lug and a connection to the headlight( actually its disconnect the existing headlight lead from headlight, plug that into the foglight harness and plug the foglight harness into the headlight.)

Under dash is even more simple, one end to the dash switch you just added.
One three prong plug into bottom most slot of fusebox at drivers left foot and a single lead into the same fuse box in the adjacent fusebox slot. Drill a hole in the firewall, pull connector thru and connect to the underhood harness. Also have to mount the relay body to ground.

This last single lead is whats kicking my @## right now. Its a gray lead that I belive is for dash/switch illumination. My fusebox has the correct slot, it's just not pinned, I'm looking for a location where i can jump this grey lead into.

My problem is I'm ok mechanically but timid electrically.
I do not want to screw anything up; lights are not in or functional, yet.

One final observation the GM stuff(used or new) is fine.
The aftermarket stuff, bumper, bumper strips and lights are crap.

Tbruz:

Did you figure your fog lights out? I have a 99 that the previous owner installed the bumper and lights, but did not hook them up. I would appreciate the info/part #'s so I could complete the install. Thanks in advance.

You can't buy the fog switch anymore, have to find it on eBay, private sale, or pull one from an escalade/Denali in the junkyard.

i need to step in here for a moment hoping the user i am looking for reads this. some one a while back posted links to someone who sells replacement wire harnesses for our vehicles. i am looking at various things and ideas but at the time the user posted links to the harnesses that completed thew fog light wiring on partially provisioned vehicles.any one want to claim that knowledge?

Anybody know TBruz who could ask him for the complete list of parts?
