Burned bulk head connection

Mattax, thanks for all the input. Let me make a short summary now:

-I don't have the original 69 wiring harness any more

-instead I have the Mopar ignition module wiring harness upgrade

-will remove the bad connector at the firewall.

-will replace the old black cable from the alternator with a 10 gauge wire, run it through the firewall and connect it to the existing wiring harness with a proper connection (actually just replacing that faulty connection)

-Discuss with Halifaxhops whether I should keep the Mopar ignition module and harness or remove it and go with Pertronix

- Run a second 10 gauge wire with a 14 fuseable link from Alternator to B (+) on starter relay.

Thanks Wolfgang
