1. I just got a new ignition switch with 4 posts in the back: batt, ign, acc, and an unlabeled one in the middle. I'm assuming nothing goes to the unlabeled one in the middle, but I wasn't sure about the acc post. Is that where I put the horn wire?
2. If I add a heater, where would that go? Through the heater switch to the ammeter and a ground? Thanks, Joe
