Wanted 1973 Dodge Dart engine harness

That’s exactly, where mine was positioned too. Unfortunately, mine was melted on one corner when I bought my car. Someone previous to me removed a black wire from that connector to the alternator and bypassed the connector as a result. But, I don’t think it was the location of the connector that melted mine. I think it was very dirty terminals that caused the terminals to over heat, melting the connector. I recently had problems with an inline ignition fuse blowing when I shut the key off. I’m addressing a few electrical components hoping it will fix that. My bulkhead terminals inside the firewall could use cleaned too, I think. I’m going to try to rough those up from the firewall side with a small bit of some kind and spray them down with electrical cleaner a few times. They are not horrible, but, they don’t look great either. If all this doesn’t work. Only thing left is try, ignition switch. I will save that as a last ditch effort.
I was lucky, when I pulled the three connectors from the firewall for the very first time the connectors looked great. When I installed the new harness connectors I used plenty of dielectric grease before plugging them in. No issues at all.
