You can repair a broken wire in the quick disconnect plug. You need to cut open the wiring harness near the quick disconnect plug, and find the broken wire. Now pull out the sleeve that was previously connected to and drill a hole in the plug to meet the spot where the sleeve was. Solder a new wire to the original harness wire, feed it thru the hole in the plug and solder it to the sleeve. Push the sleeve back into the plug and seal the new wire with some silicone. It is kinda like doing heart bypass surgery......
