I'm pretty sure one of the wires on the large round harness went to 12V and I think it is pink like all the other ignition on 12V wires. I also believe there is one that is grounded which is black with a white stripe. I can't remember and I don't have a wiring diagram in front of me so I may be incorrect about the colors.

You may not have something grounded or it may be poorly grounded.
