1967 Barracuda 4 Speed 273 back fire issue

The bulkhead connector is part of the dash wiring harness. I don't know who makes the connector in repop. It is out there somewhere as there would be no repop dash harnesses otherwise.

Year One has the dash harness 67 Barracuda for a cool $445.99 (HU306A). This harness connects everything but the steering column. Considering the past problems with the ignition switch and the value of your time, this may be a good investment.

I used YOs wiring for the Demon which was missing wiring from the firewall forward. Yes it's pricey, but I didn't have to ring out wiring and re-do half fast connections. Quality of the connectors and wire was good on what I bought.
