HARNESS issue

alexjared · Sep 8, 2025

Hello all. I am having an issue installing my new dash harness. The one I took out of my 68 roadrunner has a round bulk head connector on it. And the new harness is rectangular. I talked to techs at both yearone and classic industries and they both are telling me that my car never came with a round connector. Has any one here ran Into this issue. Thanks for your help.

Are you talking about where it plugs into the gauges?

Sounds like someone did some wiring at some time. Post a picture of the bulkhead connector and firewall hole.

Engine side '69 Road Runner. Are you sure that we are talking about the firewall, or gauges?
