'67 Barracuda Aftermarket Wire Harness, Gauges and Classic Dash
67 Barracuda
This is where I started a few years ago: I bought a new engine bay harness, a new dash harness from a friend who didn't use it, a new wiper harness, and a new rear harness.
Then I upgraded to MSD, Denso, efi, etc.
The rest is detailed in the link below.
I used the factory harnesses and connectors as the base.
If I had to do it again all at once, I probably would do it the same way. Keeping the factory wiring and connectors was a plus, and the Painless I incorporated was inexpensive and mounted in the factory location.
The correct colored, laminated wiring diagram was a huge plus.
