61558 Western 12 Pin Plow Side Light Wiring Kit Unimount Ultramount 8273 Fisher MM

A Western #61558 (or Fisher #8273) 12-pin plow side wiring harness.

If you have the 2-plug relay style wiring, there is a 9 and a 12-pin. The 12-pin is used on 2003+ Chevy and Toyota and a few others. This is what you need if you have to convert the plow from 9 to 12-pin. This is the complete harness. It hooks up to the pump and runs up into the lights. This is the same harness that comes with the Western 64078 plow lights.
