Is there a way to turn on the fog light function in a Mach 1 BCM? I have zero experience with FORScan, just know a little from reading.

I still have more investigating to do, but I believe all the wiring is there. I have a GT head/fog light switch installed, and it is sending the 3v to the BCM.

Thanks.

This video, , Bill from CJ Pony Parts installs the Shelby fog light kit on a GT350 without having to use FORScan. Seems like you should be able to turn them on with just a GT fog light switch and power. I doubt Ford left the wiring in for fog lights on Mach 1 cars, but I don't have any wiring diagrams to verify.

@TallyMach1 , thanks!

I can say that our Mach 1's do have the Gray wire at pin 14 at the headlight switch (that the Shelby was missing) that tells the BCM to turn on the fogs. Maybe Shelby specified some wire harness mods.

So it looks like there is nothing in the BCM programming to turn on or off.

Cool. The project becomes closer to reality.

I'll have the Mach in my shop this weekend, gonna pull a wheelwell liner and do some more testing. Also start to put my ideas for fog light mounting to the test.

So that video installs a Starkey harness for the fogs, I suspect because there is no fog wiring, since later there's no wire in pin 14 at the head light switch. My early '21 Mach def has the wiring at the switch... I'll find out about the rest of it this weekend.

I'll be sure to update.
