66 Valiant heat/ac fan question

Thanks Steve, I think I've got a service manual around here somewhere I'll try to dig out. I asked my brother about it and he seems to think that we've got some more wiring in storage that could be the engine harness from the a/c car, maybe that's my problem. I'm surprised though that the heater motor from the heat box didn't hook up the same way. I'll have to dig into it some more tommorow.
