I'm working on a '42 Chevy PU with the round style of heater that mounts on the firewall. I'm replacing the blower motor with an aftermarket 12V one since the truck is being converted to 12 volts and the original motor was shot. Also I'm installing one of the plastic covered wire wiring harnesses from Jim Carter. I need to know how to wire the blower motor so the fan turns in the right direction. The new motor has one orange and one black wire coming out of it. I'm planning on using a rheostat type switch like this http://www.oldchevytrucks.com/cart/product.asp?prodid=EL118&i=9764||||| to control the speed of the blower fan.
If there's a wiring diagram out there for doing this it would sure help, otherwise I just need to know which wires off of the harness I use and what they get connected to. Thanks for any help.
