    I had a straight blade Ultra mount on a 2001 GMC and want to switch it to a 2010 GMC. The dealer said Western changed wiring and was going to cost over $2000 to have old plow put on new truck. Anyone have experience making this kind of switch and any wiring tips. Thanks

    I would be looking for a new plow for that much

    Aren't the mounts the same?,I think 99-10 is the same don't quote me. All you might need is headlight adaptors.

    I would be doing it myself

    Is your ultra a relay or ISO unit? That's gunna matter the most
    99-10 mounts. No. There was a few frame changes in there spark,

    Thanks,
    I started doing it myself, mount is different I bought one and put it on but having trouble with wiring. Jumped in without a lot of research. Will have to look into headlight adapters and don't know difference between relay or ISO unit, unit was bought in 2002. Dealer explained something about Western changed polarity of lights to somehow protect vehicle computer???? didn't exactly follow. Maybe I should get new wiring harness

    I would say that might be your best bet. Not being rude but if your not sure of relay or ISO module. Or what polarity your lights are etc... You might be asking for a lot of help later on dwn the road.

    Thanks again, not rude at all. Had plow installed new almost a dozen years ago and it worked with almost no problems, didn't need to know more. Just thought someone may have had the same retro fit to save me some time, I'll get there.
