1967 Barracuda 4 Speed 273 back fire issue

the terminals are "packard 56" type. Napa carries in the weather pack catalog.

i'll look through my spare dash harnesses and see if I have a good bulkhead and connectors.

Thanks for the link...ordered the parts fun should start soon. Buying the harness would of killed all the fun...but seriously now I can use my soldering gun last time I used it was 20 plus years ago when I was playing with my RC cars.
