Rear fog light - bumper reflector lights installation.
So this was interesting (and still is).
I was able to install some of the aliexpress/eBay rear bumper lights. That part was easy. Drop lower trim panels in the rear, install new lights and run wire up through grommet into rear quarter panels.
Then I installed the wiring onto the turn signal lights. It took some trial and error but the turn signals and running/parking lights worked fine. The lights themselves came with a green, yellow, red and black wire. No wiring diagrams are available for the lights (naturally).
Here*s the two issues I ran into.
1. The brake light never worked. When I hit the brakes, the bumper lights turned off instead of getting brighter. Not sure why and not even sure I found the proper brake light wire.
2. Even worse, once I had everything wired up (clearly, there*s an issue with my selected wires) I started getting all sorts of codes/DTCs and errors at the front of my car in the instrument panel. Errors like smart braking control failure, front sensor error, etc. All hell broke loose. Needless to say, I disconnected all the wires and everything is back to normal.
Does anyone have a wiring diagram for the 2019? I*ve tried every combination and I can*t get the brake light to work and my current wiring scenario causes havoc on the car*s computer.
They looked great for the hour or so I had them connected!
Edit: just to clarify, these are not true fog lights, they are turn/park/brake indicator lights that replace the reflectors in the lower rear bumper.
