Unimount wiring question

    Hi there folks. I bought a used unimount plow, mount and wiring. The wiring going into the six relays are bad shape. Looks like a dogs breakfast as my mechanic said. I could cut them and put new ends on.

    I also thought maybe just replace that side of wiring, ends up western dealer says need to change it too new style wiring 11 pin i think with isolation module and would also require new headlights. So I may be spending more than I thought but in the long run maybe piece of mind.

    Any thoughts, I had not planned to spend this extra on it as I thought I had everything but I want it right

    thanks

    Are you using an isarmatic pump ?

    I cut all that crap out of mine, and ran new relays with a custom harness I made myself. The reality is that the system is so simple, that it works fine with relays on the headlights, and nothing else. Can't tell you exactly how I did it, except that all the wiring is fused through an auxiliary fuse panel that I bought through a marine supply store, and I used 2 standard relays for the headlamps so that my truck's system wiring is separate from the inline feed to the plow headlights, as these old dodges had some thin crappy wiring.

    The harness that you have should still be available through western! Not necessary to update all the other stuff to the isolation module style. I'm sure someone can give you the part number of what you need,like nealybird on this site. You can send him a message.

    hey thanks for the mention Western1! ... well he didn't say what truck yet, but since he says 6 relays, I'll assume it's either 99-02 chevy or 03-06 chevy. and Western did discontinue both of those a couple of years ago, because they couldn't get some of the parts anymore.

    there may be some around the country somewhere I imagine. the harness kit for the 99-02 chevy would be a 63392, and the one for the 03-06 chevy is a 64077.

    for a person with a 99-02 chevy who has a good main harness and just needs the headlight harness conversion kit with the additional 4 relays, that would be a 63394.

    there was no conversion kit for the 03-06 chevy because the main harness had to change too, to the 12 pin instead of 9 pin.

    thanks for all the replies. Sorry if im not understanding correctly. my truck is 2000 GMC 2500,

    So I can get part number 63394, a conversion kit harness which would have only 4 relays not six and would work with the plow lights I have now?
    thanks.

    sorry for confusion. the 99-02 chevy takes a 9pin main harness, a headlight harness, 6 relays, some other small parts, and battery cables and solenoid. the 63392 harness kit has all that except for the solenoid and battery cables.
    the 63394 conversion kit has just the headlight harness, any small odd parts for that truck, and 4 relays. so it is meant to go with wiring that you have from another truck, to add to the main harness, the two relays you would already have, etc.
    .. so.. it really boils down to whether or not you need a new 9pin main harness. if you do you'd want to get the 63392 (if you can find one), and if you don't need it, then get the 63394 conversion kit. If your main harness is part of what looks like a dog's breakfast, I'd get the 63392.

    the relay system worked fine. put some dielectric grease on them after you put the wires on the terminals, then wrap up with electrical tape.

    Hey guys, i'm still working on this, had a death in the family so didn't get any work done on truck last week other then extend some wire. My mechanic and I are working on it tomorrow night. Just wondering where to hook the wire that comes into the cab with the wiring plug. its a separate wire that I believe hooks into ignition?. Also what role does that wire play. I know I should probably know this already or b able to find. Time is alittle short as I lost last week and I'm trying to get my oct. invoicing done and into the mail.

    Thanks if you can help me out. or a wiring diagram or installation would be awesome.

    Sorry dude about your family...

    The red wire with the fuse holder goes to a
    12volt keyed ignition to power your controller.

    ok, thanks. I appreciate the condolences. next question. we have gone through the wiring on each relay to verify and labelled each relay. that helped make things more clear. for future reference also.

    We hooked the head lights up on truck. we have passengerer headlight, both high beams, and both the signals. we do not have driver side low beam. there are two orange wires together into #4 relay. when unplugged from relay power goes to driver side low beam plug. however when end is plugged into the bulb it does not come on, all the while the passeneger low beam will not work if orange wire is unplugged from #4 relay.
    thank you rob

    Thank you everyone for your help and comments, got it all figured out and hooked up and running .
    I feel a lot better now. Now I can wrk on extras.

    Just curious, when I tried this plow out on previous owners truck , it seemed to work great. Now on my truck when turned all the right as I return it to straight it's real jerky for first couple inches. Not sure why. I have much to learn and read but I thought I would ask as thr seems to be a lot of knowledge on this site.
    Thanks rob
