Old thread already but figured i would share my success with getting my 02 automatic headlights to stay off giving me full control and turn them on when i want them on.
Canadian truck, so almost all trucks that i know of have the auto headlights, annoying as f***,
I read a post where resistors were put in place, tried that, no go, tried the pulling the spring out of the headlight switch, no go, so i got to looking around and i remember a thread where people push ebrake in one-2 clicks for them to remain off, i didnt want to engage my ebrake so i looked at the bottom of the pedal when depressed the light goes out, so i unplugged the wire from ebrake assembly, put a spade connector on a wire, pushed it into the wire that plugs into the ebrake assembly, grounded that wire and voila, done.
No more auto headlights, takes 5 mins to do tops.
