Pin #20 on the C101 connector has to be clipped, otherwise un-fused +12v gets connected to a ground.

I sold the motor and I gave the shell to my little cousin. I will pass the information on.

Sure you had the correct relay in there?

Witch relay is the correct one?

Needs to be the correct "main relay" one....not just any relay will do and will definitely melt the wiring.....should be a white one

The white relay I got with harness is the relay that would melt the wires. I used another relay from another car it also melt the wires for the main relay
