One wire Alternator
I am currently installing a (exact fit A/C system) from Classic auto air, I purchased this in 10-2022. Not in any big hurry. The directions stated that the system needed to be converted to a one wire system with a alternator from a GM or chevy pickup. I called NAPA and got one and have installed it but have not tried to start it as I am still doing other stuff to the car. Question, The thick wire , white with a black strip, fastens to the back of the alternator, I assume. What do I do with the other wires? The NAPA guy said to 'tape them out of the way'. Anybody have any good suggestions, the NAPA guy may be correct. Thanks, Joel

If you search Swapping Generator for One-Wire Alternator, you'll find several videos.

If you want the GEN light to function you need a plug (assuming you are using a GM type).
I used a Jegs alternator 140 amps. It’s considered a one wire but it has a rubber plug to remove and the GM plug goes in. One wire goes to 12 volts the other goes to the light
My light works as normal it lights up when the key is on, once the alternator starts charging it goes out
