I don't know the application, but I quickly found one that works. My offer stands - if you have the harness out, send it to me and I will put new terminals on it with the new connector for you. Just cover shipping. The wires would be just a little shorter.

I think the one you have is original.
The location and angle of the flange makes it a bad candidate for a C body. I still kick myself for not buying that NOS C body one at the nats one year for $40. I was too tired to carry it. LOL!
Is that one cracked? It looks fine to me. They are recessed like that, at least I know my 67...
I looked at the FSM for 66 C body, 67 B Body and 67 C body. There are subtle differences. 67 B body calls for the Black wire to have a tracer and 67 C body (66 C Body that wire color is not called out) is just straight black. 67 C body has 2 light green wires connected together all others...
Ross - look at the attached pdf. The layouts are pictorially correct and roughly to scale. This harness should be from a 67 B body - almost positive that the B Body and C Body should be the same at the switch, I can verify if necessary from the FSM. The 67 should be the same as your 66. I...
Well I have one in my hand that is probably correct. Its a 67 harness so I believe it might be the resistor end. But I can check as I have the same switch as yours to check against. When I get a chance I can look through my extensive old connector connection and see if I can match it up. I...

Don't trust NOS. I have NOS in my 67 Coronet (same one) and its bad. Not all functions works. I have several NOS ones and I will be rebuilding them along with the blower switch (my spare is bad). I just have not had time yet.
I have the capability to machine most of the parts including the...
