    Has anyone changed out their fisher plow lights using the peterson ones from Northern tool? Would you know what color wires go to the correct color on the fisher plow harness which is 11 pin. The colors are all different, There are five wires each out of the peterson's and 6 on the plow harness =one larger wire which is black/orange which I think is ground.
    I would appreciate anyones help............Thanks

    I actually spent $210 between the lights and the harness.I just did mine on tuesday.Open up the light housings.You will see 5 wires.the white wire is for ground and splits off twice.I cut it in half and wired one for the ground for the headlights and the other for park and turn lights.The rest of the wiring is as follows:
    Green-low beam
    Red-high beam
    Blue-turn
    Yellow-parking lights

    mine didn't have the black orange wire.It was a intensfire harness with the plugs on the end I was going to use to convert one of my mm1 to a 3 plug but bought new lights already wired so that was in the extra parts box.

    Mrmike- if you're still out there- did you ever get the Petersons to work on your Fisher? I'm having the same problem. Chevyzrule has the turn has the turn and parking light visa versa,I can't imagine why....? Anyone out there that has ANY answers,would be greatly appreciated.

    Did you use a test light and check for power out to the headlamp assembly? Write down what color does what. Then wire up per your new headlamp directions.

    Well if he's like some of the mutts around here, might still be driving around with busted lights. OP, weren't you on another thread here same problem? Post your problems in detail. You will get some help

    The issues are that I only have power for low beams,coming from truck- that's it.

    Go to the module with the wiring diagram. You should have headlamp power in. Then headlamp power out to the truck. Connect the plow, the module should switch over. Do you have power out from the module for the non working lights. A test light and a digital DVOM is very helpful. Can diagnose almost anything on your plow with those.

    And you have the wiring diagram. And as was stated in the other thread, you need to test light for power. And make sure you checked the fuses

    Thank you both. I'll check the fuses that I hope are inline and easy to locate. The two fuse boxes have been checked and rechecked and rerechecked. So frustrating.

    Per the wiring diagram, is there power into the module?

    I used my power probe which is a test light,and also displays voltage.You can use the switch on it to send power to something.For example attach the ground wire from the power probe to one side of a standard automotive light bulb.Take the probe end and touch it to the other end and send power to it and the bulb lights up.When I wired those lights I had the diagram of the pins on the end of the fisher harness.I commanded them to do what the diagram said before I closed up the housings and mounting them to the headgear.As stated above check all your fuses before you go chasing wires around when it could have just been a simple fuse.Invest in test light or voltmeter it's a great tool to have in situations like this.

    Chevyzrule-do you recommend a particular power probe ? Also-There's two grounds in the harness, should I ground them separately,or can I join and ground them together? I'm pretty sure I've done them together in the past,just want to be sure. And,I found two inline fuses on drivers side. One was blown(the 15 amp). The 7.5 was not blown. It's going to warm up this week, so I'll attack it again then. Does anyone know if there's more than two inline fuseThanks again, all.

    Power probes are not cheap. Did you ever do any of the checks that were stated?
