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
