AMX A/C refurb and wiring sort

Looks like to original poster's question has been answered, so I hope I'm not hijacking this thread, but perhaps someone here will know the answer to my question.

My NOS a/c wiring harness came with an extra pigtail on the white wire (see photo).  There is no such pigtail in the photo Bill posted earlier.



Based on the length of the wire, and the factory a/c wiring diagram http://planethoustonamx.com/main/amx_javelin_ac_wiring.jpg I assume that the white pigtail goes to the blower motor (left) terminal on the resistor. As you will see, the blower motor is presently connected there (orange wire).  My question is, should the white pigtail and the orange wire to the motor both be connected to that terminal, or should I just cut the pigtail off? It appears to me from the wiring diagram that the second white wire should connect both to the blower motor and the terminal.
Thanks!

yeah im thinking that pigtail is redundant, for whatever reason. from what ive found, that is the straight through direct wire to the motor. which is what that orange/red wire on the left is going to, so i'd assume its not needed?

That white pigtail wire does not belong there. It can be cut off. The A/C harness has only two wires, the white for the high blower speed, which goes as shown on the resistor block. The "output" side of the resistor block is the single terminal that goes to the blower motor. Your blower motor is a replacement, the OEM motors were sealed at the end and the power + lead was white where yours is orange. The A/C harness was routed along with the regular blower harness and the brown compressor lead follows the main body harness along under the washer bag and along the right inner fender. AMC used a thin metal tie wrap to hold the A/C, two wire harness to the main harness in the area of the blower motor. billd's picture clearly shows these tie wraps. Ultimately the brown wire female bullet end pokes out near the voltage regulator where it meets and connects to the compressor clutch (black) pigtail. There's a rubber dipped, metal wire retainer under the right front compressor bolt that holds the clutch wire close to the compressor base.
