    yea I checked all grounds and connections seem to be good. Plow goes up and down and left right with no issue just no lights at all not even parking lights. Im at a loss worst case I will just say screw it and use the truck lights just wont see crap lol

    Maybe take the truck light/plow light switch apart and connect the two wires.......if they turn on then you know you have a bad switch.

    Its tricky but 11 pin wiring but swaped and put 13 pin connectors. Its on a 1999 chevy suburban 2500 series. Just don't know why it would stop working out of know where. I did adjust the lights on the plow cause they were up towards the sky but don't think that would affect anything.

    There's your problem. On an 11 pin all lighting is grounded via the plow, namely through the lights and into the light tower itself. You disturbed the lights and therefore they lost their ground. :nod:

    Ok so just take the lights off all the way and bare some metal and re install?

    Correct. Clean them up good and retest.

    ok cleaned up real good and still no parking lights or head lights. But did realize I have turn signals working on the plow. So could it be the switch in the truck or maybe connectors where they tie into the main trucking head lights?

    If the turns worked before and you didn't realize it you lead us down the wrong track. Instead start at the truck side bumper connector and check for headlamp and parking light power there. If you have it then it's still a ground issue on the plow side.

    lights

    Do you have lights on the truck with out the plow plugged in? If so i would start at a bad switch for the plow lights.

    It will not be a bad switch, because if the plow/truck switch was not operating correctly, the turn signals would not work on the plow.

    Not so. The headlamp position switch has no correlation with the turns signals (or parking lamps) what so ever. They are wired completely independently.

    Had the same problem last year and B & B helped me out. It was a bad connection in the 13 pin harness truck side because I had wired a new 13 pin plug on. Can't remember which pin it was but I'm sure B & B can tell you

    Well looks like I have a short in the harness where the 13pin connector was spliced in. Thanks only took going threw this in that to find it. Now to figure out where its leaking hydrolic fluid man its one thing after another. This better not be a sign of how this winter is going to go for me.

    When the plow/truck switch is in the truck position, all the lights on the plow are NOT off? (just the headlights) I thought they were . I'll have to double check myself now. I am sorry for that mistake, and thanks for correcting me B&B

    As I stated, the plow/truck toggle has no affect on the markers or turns what so ever, only the headlamps. Turns and markers are wired directly to the plow, not through any type of switch or relay....regardless of the age of the unit, 11 or 13 pin etc.
