so i spend some time today going over the diagrams, and looking at the fog light circuit.
it looks like the lights should be isolated from the switch before power is directed to them. otherwise, the light switch will be probably damage.
not a big problem, will just have to use a 5 legs relay.
i also tested the wire that comes from the BCM, and basically going to trigger the relay.
wanted to confirm that the relay will not chatter when the power gradually drops, and the lights are dimming out.
i made a short video of the process.

after filming the video, i thought it will be a good idea to add a timer to the setup, so i will be able to control the length of the "On time" after locking the car.
so i will probably get something like that, and also use it as the relay.
might even go pro and add a Photoelectric Switch :dance:
