    I almost think you have a battery cable for an ISO setup. Is the connector kind of like a pencil style connector; looks something like this...

    Maybe this will help. Here is a side by side comparison of where the wires are supposed to go.

    .....Ground to motor relay you mean? Just chop off that current connector, then splice in additional line if you need it to close the distance to the motor relay using a butt connector and appropriate wire.

    Now connect a ring terminal on the other end of that to attach it to the motor relay. It should be connected on a small terminal with the black/orange wire that comes off the control harness.

    sounds like you have a battery cable from a iso system. Does the wire come from the ring terminal / ground side at the battery?

    Can you post a picture of the wiring? Where did you get these harnesses, were they used or new, and you do have the 9 pin control harness correct?

    Keep in mind you can kind of wing it and forget about colors and focus on location. These 2 red wires that you speak of are kind of throwing me off.

    Crash has more experience in the old relay systems then I do, but this section of it is pretty straight forward.

    Your motor may run, but until you have correct current to your control side of it.....it won't function.

    it is a used wiring harness that came with the plow except for the power wire that connects to the ground of the battery and the selenoid and sticks out of the grille (that didnt come with the plow so i just bought it)... im just trying to make it function and im not worried about the headlights at the moment... it is a 12 pin.. as you can see in the picture, the battery ground has the orange/black wire and the main large wire attached..im confused as to where that black and orange wire with the end you pictured above goes and the red wires

    the picture is kind of fuzzy, are you holding two or three wires in your hand? ...red / red / black - orange?

    Is it possible that the one you call green / black is in fact green / brown

    This looks like a 12 pin V blade harness and not a straight blade. I think the two reds are supposed to connect to the battery grill harness, and where you don't have the right harness.... I'm willing to bet they weren't even used before.

    Separate the two wires that you already have hooked up to the solenoid in the picture. Atach one on each small stud. Connect the black/orange directly to the ground side of the battery and see if the plow FULLY functions. If not, I would say those two red wires need to be hooked to power. If all is well, then leave the two red wires untouched.

    You can actually just connect the two black orange wires via a butt connector where it is already coming from the ground battery terminal.

    If the one you just bought only has 2 then it won't work.
