Any reason why you didn't go with the factory Silverado LED fog kit for $221?

[syllaj]

Because this kit worth 350-400 in Canada! ?

For the last 10 plus years u don’t need to go thru the firewall, everything is under the hood in the fuse box.

When adding the fog lights kit from GM, Do you have to pay the dealer to program or does it come with it/an authorization code?

[Transient]

Dealer needs to reflash bcm, iirc

[chieffie]

hook them up to low beam circuit

I asked today. Dealer wants $160 plus my truck for a half day to PROGRAM the lights WITH the activation code. I paid $235 for the GM accessory lights only to find out it's going to cost me more than half again to have them activated! I should have went with the cheap kit and just an on off switch. Going to tap the parking light signal to have them come on with my Fleece Performance High 6 module.

 

As for the OP. There is a rubber tube on the firewall on the passenger side that you have to cut to feed the wire through to the inside. This is what the GM Accessories kit has you do to run the trigger wire from the BCM harness to the fuse block under hood. I believe there is a similar tube on the driver's side, but I haven't looked for it.

Confirmed there's one on the driver side.   It's between the engine and the brake cylinder.  Very accessible.  Comes through above and behind the brake peddle a little off to the right.  Much more accessible than the one on the passenger side, imo.

Yes, there's one on either side. I've used the passenger side with no issue, taping the wire to some sort of snake (coat hanger) really helps to get the wire through the tube easier.
