26346 Western Fisher Isolation Module MVP V Plow Control Harness 10 Pin Round Plug

A New 10-Pin Western / Fisher Harness # 26346 and 56496 part bag.

This may be the harness you need if you have an early Western MVP V-plow or Fisher EZ-V. They use a 10-pin control inside.

There were several different wiring systems for this plow. The original set was a 2-plug relay wiring and it used harness 66610. Then, they had a later 3-plug relay harness. The last version is the isolation module wiring which is what you are buying here. This plugs into a 3-plug plow that has a module under the hood. This will plug into the plow side part # 26358.

If you are converting over to this, you also need the Isolation Module and the Headlight Kit. The nice thing about this newer harness is that you can also run a straight blade with just a control adapter 66760. This is 7-pin out at the plow.

If you want to do 3-port, you need the Isolation Module 29070 and truck specific Light Harness and truck side Power Cables listed here.
