    I Have a Unimount. Today I converted it over to a 3 plug harness (28053) to match my truck. The lights work but thats all. The controller lights up and I can turn the power on but get no pump responce. The plow is on a 2001 chevy surburban. It has a 3 port iso system. any help would be great.

    All grounds hooked up on plow side?? Three pin connector is just for your coils, I can't remember if they have a seperate ground like a regular unimount, or are piggy backed onto the light harness.

    Yes the 3 pin has its own ground. Make sure that is hooked to the ground on the motor!

    The brown wire going to the 3 coils is the ground & needs to go to the ground on the side of the motor. Check the spade terminals going to the coils.

    I am have a problem. My light on my truck wont switch over to the plow. I have a 8ft western uni-mount pro. I converted it to a 3 plug sysytem to match my new truck. When I hook it up it dont not even try and switch over. Last week I had a ground problem and the light would keep switching from truck to plow now it wont do anything. The Plow works just fine( up, down, left and right) I t just dont have lights. I have taken the B & C plugs off the control box and switch them and the light flash truck to plow but it I have them in their labled spots they dont do anything. Please any help would be great.
