A New Genuine Western / Fisher Truck Side Repair Harness (# 43910 AKA 22338K ).
This is the same for both Western and Fisher. It was used on Western Unimount, some Ultramount and Fisher Minute Mount plows. We recommend replacing the whole harness, but this is the cheaper way. It is for 12 pin relay style wiring.
The plow side repair end is # 49319. If you need both the truck side and plow side, they are sold as kit # 49367K.
Don't forget a tube of dielectric grease and the covers to protect them in the future.
