    You could probably buy some repair plug ends for the truck side (three plug) and jerry rig them into the existing wires. The main power plug should be the same but the other plug, on the uni, will have the lights and the control wires combined into one plug. The new ultra mount isolation module does exactly the same thing switching the lights from truck to plow. The only difference is the iso module is intigrated into one neet box whereas the relays are loose. The control still runs on the same principal. There will be three control wires and one common ground or common positive (doesn't matter which). The coils on the valves are exactly the same and draw the same amount of power on the ultra as you uni did so that is not an issue. Your controller will work fine as long as you hook it up correctly.

    I might have to disagree with you mishnick. The coils are positive switched, not ground.

    That depends on the plow, some have common positive and others have commn negative, but the point is it doesn't matter which way the power goes through the coil, if they are energized the valve will transition.

    Get a unimount wiring harness.

    All the ultramount and unimount coils are all the same wiring. Unplug the 3 plug wiring and plug in the 2 plug. Keep your truck as a 2 plug
