    My vehicle side battery cable doesn't have the small black/orange wire that comes off the neg side (next to the battery in the pic). I have the other end though, do I need to snip that end off and run that to ground.

    Another question, the single red that goes into cab with controller wire, where are you guys running that to on the GM trucks?

    Clip the end from it and run it to the neg battery terminal. Same destination, just no connector.

    What year GM?

    02..I was all over the fuse box and not one acc plug in there. I remember when you used to get 3 or 4 extra spots in the older GM's.

    Look in the dash fuse panel near the top for a fuse labled "SEO". If it's there use it. If it's not (not all trucks have it) then get your ignition power from the MBEC below the dash on the left side. Will be the top left hand plug, just to the left of where the trailer brake controller plugs into when adding a brake box. See this thread here.

    Thank you B&B, I do have the SEO, I was just under there looking around before I asked.

    Still have a problem somewhere so I am including pics. Maybe you can see something wrong here. Everything is wired, I've got power from the MBEC, bought a new joystick from a member so that should be good but the light won't come on and there is no movement. I've tried each plug and there is no power coming to the joystick. I also noticed when its plugged in that none of the colored wires line up plug to plug. The motor relay is also new.

    I havn't blown a fuse yet and I've been checking them every time I do anything. I just checked and I have power at both fuses on the harness.

    I have a Fisher plow, but wiring is all the same between Western/Fisher. I only have the handheld controller, but it won't turn on unless the plow is connected. I can't say if the solenoid box joystick is the same way, since I don't have one to try. Maybe?? Are you trying with the plow plugged in?

    This applies to iso module systems. My older headlight-relay 2-plug Fisher would turn on regardless if the plow was attached.

    I did pull up next to the plow and plugged in the battery and pump plugs, I havn't mounted my lights yet so that plug is still empty.

    Thats what I thought but I thought I would ask before I messed with it. The green and blue are the only 2 that line up in the connectors.

    Well don't feel bad I just whent thru the same thing did all the wiring thought that I did every thing right. Hooked it and NOTHING works can't get the controller to lite up. So I said uncle and droped it off at a local Western dealer, if you don't have it figured out by the time I get mine back I will make sure to ask what I did wrong and pass it along, Maybe it will help you maybe not.

    The colors between the harness side of the plug and controller side of the plug do not match color for colorexcept for the green and blue wires.

    You need to have the plow plugged in for the controller to power up.

    Have 12V on the red/yellow wire in port #1 on the Iso with the ignition on?

    How about ground on the black/orange wire at the controller plug?

    It wont work. You've gotta have all three plugs hooked up for the controller to come on or even be back lit for that matter


    I just went through this this weekend.-Still waitng on my lights too.

    port 1 has all red wires and 2 browns, 3 of the red have power with ignition on. 2 up top towards port 2 side and the middle bottom plug.

    Also have ground at the black/orange wire at the controller.

    Plugged my lights in and everything is working except my plow lights. My running lights come on, truck side, but no headlights at all.

    Going to have to leave that to the pro's. The only thing I can think of is that the lights are grounded when you bolt them down- That doesnt make sense though.

    At least we are heading in the right direction.
