Guys I have a question on how to connect the heater blower motor to my new wiring harness on my '66 coupe. It seems that the two black wires are grounded to the motor frame, but do I need a resistor between the power (orange) line and the motor? I seem to be missing a connection piece to the motor. Any suggestions?

You need the capacitor that connects between the orange power wire and the positive terminal on the blower motor, all the usual vendors have them, this photo is from LICS their part# 53-03C
But where on the motor do I plug in the orange wire?
The only connection I see is for the ground connection? I must be missing something?

The 12V connection is a rubber-insulated male spade at about 5:00 on the motor flange - it takes the rubber-covered female terminal on the black wire from the radio capacitor (or on the orange wire if you're not using the capacitor). The blower ground connection is a bare spade terminal screwed to the motor flange right next to the 12V connection.

Thanks so much, JohnZ. Looking at my blower motor, all I have is the male stud at the 5:00 o'clock position. I am missing the the bare spade terminal screwed to the motor flange and the 12V Connection. It appears I may need to order a new blower motor with the proper connections?
Here's another showing the wiring. You have the correct 12v terminal there on the motor, no need to change that. You're only missing the brass 90* male terminal that is held in by the screw shown at the rectangular connector.

Thanks much, Rich. Now I see the problem. So I could connect the Orange wire directly to the 12v terminal and then attach the ground wires to a screw on the motor? Do I have to buy a "brass 90* make terminal?
Yes, as John said, if no capacitor in series, just plug the round Orange terminal to the 12v motor terminal. This is what they did if no Radio.
Yes you can connect the 2 Blk/Wht grounds via a jumper of some sort to the ground screw and it'll be functional. Since you have a new harness you probably don't want to cut the plastic terminal connector off.

Thanks, Rich. I think I am good to go. I can't tell you how much I appreciate your help. You Corvette Guys are awesome!
