I'm working on a harness for a set of fog lights on a '21 Mach 1. I'm using a GT headlight switch which has the foglight function included. I'm not paying hundreds of $'s for a harness that only partly does what I want.
Can anyone confirm my suspicion that the headlight switch simply controls grounds to the BCM? I've done a lot of searching and this seems to be the fact. I do not plan to use the BCM at all for this project, just the headlight switch.
I'm also looking for confirmation that headlight switch gray wire pin 14 as being the one to cut into (going into the headlight switch) to get that foglight switched ground for a relay.
Please dont ask about lights, mounting, etc. I have some thoughts on that, but no real work yet. I'll post up when I have something complete.
Thanks...
