I now need to understand the correct Postitive Cable wiring for my 68 Camaro 350 with the alternator on the passenger side. The car is quite rigged right now, and does not even have the small radiator support mounted junction block in it. It looks like a new Battery Cable will go to the Starter with the pigtail going to the small junction box on the radiator support. My question is what else connects to that junction block and how to get the hot line to the alternator? I assume a wire goes from the junction block over to the horn relay and on to the rest of the car. My question is where does the alternator red wire line attach in this configuration? Does it also attach to the junction block as a 3rd wire, or does it come back over from the horn relay, or should there be a second pigtail wire on the battery cable, or do I get another wire and somehow attach it to the battery post and over to the alternator. Thanks for your help.
