Good people

Before I go down the road of purchasing another 2 speed wiper motor, I am going to test the motor that was in the car when I purchased it. The motor was never wired and was missing the resistor.  I have purchased a NOS resistor and a wiring harness from Classic Industries. I have the 2 speed switch that was in the car and after testing the switch it appears to be working fine. What i need now is a little help wiring this thing up.

Can someone please tell me what each color on the harness is for? Which color has which value? Which is constant power (if not red), which is negative, which is ignition? I am attaching a link to the wiring harness I purchased if someone wants to look at it.

The main wiring harness the car came with was a inexpensive drag racing harness that the builder simply added to it instead of using a more expensive Painless system. So I am not sure if seeing a diagram of how the factory harness was wired to the 2 speed wiring harness would help.

I do have one other question and that is what was the cooper piece bolted by the resistor used for? I do not have this piece and need to know if it is needed to make the motor work? The resistor I have has what looks to be a cooper strap that secures it to the motor. I am just unsure what the intent of the other cooper piece is and if it is needed.

I hear @Slotts (https://forum.e-bodies.org/mlist/slotts_104) is the expert when it comes to this subject.

Any help you could lend me would be greatly appreciated. Thanks and God bless.
