    Fairly sure it will, isn't it 1 plug for control, one for motor power, and one for lights?

    I think plugging in the lights somehow "wakes" up the Iso - Mod
    Mine dosent allow the Fishstick to be on untill the lights are plugged in.

    Connecting the plow side light harness completes a ground path between the #2 and #7 pins in the truck side 11-pin plug. To run the plow without a plow side headlamp harness simply jumper the #2 and #7 pins together on the truck side plug. Doesn't matter whether it's a 3 or 4 port system, the trick works on either.

    Nice for diagnostic purposes without having a plow handy. Thumbs Up
