You are correct that the harnesses are the same but I currently have two 65's and one stays on while the other goes off, I had the wiring spread all over the garage floor when I wired the blown car last spring and I didn't see anything different that would cause the lights to stay on or go off within the wiring harness or the wiring diagram, it has to be within the switch since that is what turns the lights on and off. This has me wondering now, I may try and get the switch out of my stock 65 and see if there is a different number on it.
I've had dozens of other early A's over the last 28+ years I've messed with them and some stayed on while others went off. My parents 65 Barracuda had the lights go off also but they stayed on in the other 65 I drove back in the 80's. I never drove my 64 Barracuda or either of the 64 Valiants I had so I can't say for sure what they did. I'm pretty sure they stayed on with 65 Valiant I sold last year though. I'm a little curious about the 66 I have so I guess I need to check it out and see.
