Okay, now the horn isn't working. Looking at possible replacement of relays from local auto parts store. Is a close analog available that will work? Looking to avoid spending too much for now. I haven't had time yet to look more closely at the wires and everything. I am guessing I will need to remove the tape wrapping everything. Also, I think one of the small black relays is what I want to replace. Am I right? Or is it the big red unit in front of the relay section?
