    alright. i think its wired up properly.

    i have power to red wire that goes to controller harness from fuse box.

    black/orange wires are grounded. hear the box click when i plug/unplug them

    red/green wire is to hot side of solenoid.

    plow lights work. jump the solenoid and the plow angles right. tried 2 controllers, and 2 solenoids.:mad:

    EDIT 1: In port one of the iso box, i have 12v going to the red wire. now i think i should have 12v to the red/yellow wire with the key on and plow plugged in. but i dont.

    IF I apply 12v to the red/yellow wire, everyting works. i suppose i could just install a batt+ switch but thats ghetto.

    EDIT 2: The plow is a unimount from my dodge with a 3 port iso module. this ford has a 4 port. will that cause this issue?

    FIXED IT!

    Found that i was not getting power to the iso module from the controller fuse. even though the fuse was good. cut off the sheathing, and found a spot that some previous owner had probed and corrosion got in and created a brake. repaired it properly and im in bidness!
