The previous owner had converted his harness to single but only by taping up unused stuff and allowing plugs to hang around the motor that weren't necessary.

That being said i obtained a fresh harness to work with but I'm having trouble identifying certain plugs either bc they aren't needed or are too old to tell... heres a couple pictures with what i believe to be the old wire colors.



All three are these 2 pin, black female plugs with yellow centers. They are colored as follows
Blue and white and silver dots/ Black and white
blue and tan/black and white
green white and silver dots/ black and white

 

This one as well? It's the only blue one on the harness

also get the factory wiring manual (can be found easy) and dig around. Will help you a lot

 

I have been through at least 3 threads with that picture. The colors are hard to make out and didn't know if someone knew off hand
