Hey all - I have a 2019 Tahoe LT that did not come with factory fog lights. My plan was to install some - and after researching I decided I wanted to be able to control them separately from the headlights (so that eliminated the Gen5diy kit - that only allows your aftermarket fogs to be turned on with the headlights). I also did not want some funky looking after-market switch connected under the dash, or stick-taped to anything so I did some digging into cmatt's solution. Matt had me check some factory wiring to determine if I could use his kit on my vehicle. A couple of the wires did not match up to what Matt had in his diagrams, so after some emails back and forth with him it was theorized that I had a "fleet" vehicle. A quick check of the code in the door jam/VIN confirmed this. Matt had me test for voltage at other wires and after reporting back he said "no problem - I got you covered!" I ordered his harness and a set of LED fogs from CARID (https://www.carid.com/2019-chevy-tahoe-fog-lights/lumen-projector-led-fog-lights-1233543783.html
) and away I went. Getting the actual lights installed was super easy, trying to find a way to run the wire from the junction box under the hood to the fogs proved to be difficult, at least different, from what I was expecting.
Matt's directions were to run the wire from the junction box (see "c" in my photo below), along the hood release cable, across the top of the frame over the radiator, down the side of the passenger headlight (see "b" on the photo" connecting the lead from the junction box to the harness that connected to both fog lights under the vehicle. On my Tahoe I could not find a good path on that side of the engine bay to run the wire and I was not able to remove the grill to run the wire - at point "a" on the picture the grill appeared attached to the bumper in a way that I could not separate the two - so I set off to find another path.

Point "c" shows the junction box, so after following Matt's INCREDIBLY detailed instructions on how to access the box, and add the necessary wire, I found a path through hole with the upper arrow. You can see the same wire where the lower arrow points. This put the connection directly at the driver's side behind the newly installed fog lights.

I swapped the connection between the two fogs so the wire from the junction box could now be connected on the driver's side. Now at this point, the fog lights are in, and wired to the junction box.
Matt provided me with a link to a really good deal on ebay for an OEM headlight switch WITH factory fog lights - so I swapped that, and wired the rest of his harness per his instructions and videos. At one point I got stuck and could not locate a connector Matt referred to in his instructions - so I reached out and he responded with another picture, and video to help me out. After that I was all wired up - a quick test revealed everything was working PERFECTLY.
A couple of notes with the way this worked in my Tahoe:
- there is no fog light indicator on the dashboard that comes on when you turn the lights on and off - no big deal, you can tell they're on
- I can turn the fog lights on no matter what the headlights are doing. On, off, brights, parking lamps, it does not matter I have complete control over the fog lights -through the OEM switch.
- Matt's kit does NOT require running any wires from the cabin to the engine bay
- Matt's kit utilizes the factory fuse for the fog lights
- the relay box that Matt provides needs to be "secured" to something under the dash. I ended up using velcro tape and attaching it to the back of the BCM to keep it out of the way
- NO FACTORY WIRES WERE HARMED IN THE INSTALLATION OF THESE LIGHTS AND MATT'S KIT! Everything can easily be undone, and what's better the install looks mostly OEM anyway!

All in all - I am VERY pleased with the look, the investment (time AND money) and the support/help Matt provided. If you're thinking about doing it - do it - I HIGHLY recommend his kit!
