i have a 1965 olds dynamic 88 convertable. there is a junction box mounted on the driver's side fender well. the battery cable, starter cable, engine harness feed, circuit breaker wire, main harness feed wires all bolt to it. there is a plug on the side that has a green and black wire that run into the wire harness. this junction box is broken and i can not get a replacement. if what i think is right. all this junction box is is a distribution center. i was wondering if anyone has any solutions for a new one. stereo store sells a distribution box where you would put your main wire on and then put the rest of them on the screws going out. would something like this work. and what is the plug on the side for.
also one of the red wires thats tied into this junction box runs over to a long rectangle box on the firewall. then there is a orange wire that runs from there into the firewall. that box pushes into a small rectangle box that is mounted to the firewall, but the large box doesnt always want to stay in the smaller box. what is this for? there is a piece of metal that looks like a contact point on the back of the larger box.
