I am replacing the stock type under dash wiring harness on my 1967 Firebird.

Don't forget Performance Years! ($400-$450, but is NOT factory original style). They all will work fine. If authenticity is critical, Ames is usually the best choice. If you're not showing the car for points, it's down to cost.

Thank you Mark!

I replaced all the wiring in my 67this year with the kit from American Autowire. It seemed to be the best quality among the well known after market brands. It included all the connectors for the lights, and it plugged into the existing instrument panel easily. Customer support is awesome.
