I have a 2002 Sierra SLE that did not come with
fog lights. I had the OEM fog lights installed
by the dealer.
They only come on when the following conditions
- Headlights on
- I press the fog light button
The factory fog lights, for me, are not particularly
functional, but rather are aesthetic. As such, I'd
like them to come on whenever the headlights come on.
Is it possible to program the truck to turn them on
whenever the headlights are on? The fog light button
is not a switch, just a momentary-contact button that
signals the computer to turn them on. I'd like them
to come on automatically without having to rewire
