You will probably come out better price wise.

The factory switch is the way to go, keep it simple, fuse your hot wires, use a relay, pick a wire that is only hot when the key is on.



You might visit the dealers parts dept for anything that will help like connectors and wire pig tails.

See link below for the factory switch.

the factory switch is the way to go other than itís a momentary switch not an off/on switch youíd have to make up some circuitry to make that trigger and KEEP ON a relay like an on/off switch would this is normally done by the back, but since the factory harness isnít wired for the switch on an ls or lt, i doubt its possible to use the bcm

so appearance wise, yes itís the way to go but not for functionality

if i could figure that out id have them on my car already but i refuse to drill holes and add an aftermarket switch... i just donít prefer how that looks

For those who are considering adding the premier fog lights to the LS or LT and don't mind adding a non-factory switch, this is the one I used with my install. I placed the switch in the black panel below the light switch. I interupted the low beam trigger to the first relay. The switch has a blue LED, closely matching the instrument lighting.

So I havent completed this swap on my wife's 2018 LT, BUT, I believe I have all the components. The factory engine to body harness will have the Brown/Violet wire already in it. I was going to build my own harness and pin out this connector on the other side, but for $50 I got a factory GM harness that is plug and play with turn and fog connectors.

For inside the car I got a factory headlight switch with the fog button. I'll pin out the empty hole and run a wire to the BCM connector for the fog lights and (fingers crossed) voila. I believe you only need the BCM reprogrammed so the indicator like on the dash illuminates, but we'll find out.

Did something similar with my 2019 Silverado with the factory off road light button.

on my cruze you had to have it flashed, hooked the whole kit up and it didnít work till it was flashed. probably because itís a momentary switch that triggers a relay in the bcm and not just a standard on /off switch. also to save you some work, then bumper harness with the plugs for the fog lights separates from the rest of the engine bay harness and for other people wanting to do it the way you are, the bumper harness can be had relatively cheaply online

Wanted to share some info:

1. The factory harness that includes the fog light hookups has a different turn signal plug than the non-fog light harness. With fog is a black connector. WithOUT fog is gray. The black connector will NOT plug into the gray bulb socket. You can get the black bulb socket for your turn signal (ac Delco # LS309, GM 84152979) or swap the black plug off the new harness for the gray plug off the original.

2. The entire front bumper cover needs to come off to swap the harness. There are 3 "hidden" fasteners, 2 up under the headlight in a bracket that connects the bumper cover to the fender (T25 Torx). The other is behind the fender liner going down from the top into the same bracket (7mm). If you find the one behind the fender liner first it might make it easier to find the torx fasteners.

3. The fog light wire is in the vehicles main harness. It runs to the junction on the passenger side of the vehicle. Its pin 16 on the engine to body harness. The body harness connector needs the female terminal and wire added, then connected to the body to front fascia connector in pin #12.

Update to my update. I ordered the other bulb socket for the turn signals. Turns out the eBay fog light housings I ordered use the gray holder, where the oem housings with the fog lights use the black socket. They are not only different plugs from the harness, but they are also a different layout of locking nubs that fit the socket to the housing... 😑

FYI

If anyone is looking for the part numbers for the blacked out OEM Fog light/turn signal housings like off the midnight edition Nox

84779712 - right


Just had surgery last week so havent been able to tap the wire to the BCM yet. Hopefully next weekend.

I also have a 2018 LT and would like to do this as well so I'm very interested in how this plays out.
