Hey, congratulations on answering everything I didn't ask. (1.) I know how to disarm the factory alarm and (2.) already have a Honda-SL3 bypass module from iFAR.

I wanted to know where the factory alarm module was so I could use the horn trigger to activate the remote start. I've already probed the steering column harness and found the horn circuit (green/yellow). Unfortunately, it is a separate circuit unaffected by the factory keyless double tap of the lock button. The horn chirps when you hit the lock button twice for those that don't already know.

I'm pretty sure the FASD wire in the door will lead me to the keyless module.
