    I currently have wideout plows on newer chevys all with a 2 wire set ups on them. I also have a
    ultra mount 8' pro plow on another new chevy with a 3 wire set up and I'm looking for some
    help to determine what I would need to convert it to a 2 wire set up so that I can interchange all the trucks and plows as needed? I know I need a different controller for the pro plow as well. Anybody that can shed some light on this for me, it would be appreciated.

    The conversion will be done on the truck side,your wideouts use multiplex wiring which your pro plow doesn't so you'll need a controll harness and IIRC a battery cable hooked to a selonoid(your wideout has the solenoid on the plow) and i believe a controll harness adapter,i'll have to look up the part#'s

    I'm also curious as how to do this-

    I have three styles of ultra's

    Old two wire, three wire and then new two wire.

    The old two wires are easily converted to the three wire setup.

    Is the chevy with the Ultra using a 3 port or 4 port Iso Module?

    I'm assuming your trucks with the wideouts are 3 port,you can go 1 of 2 ways here-

    You can get kit #26705-1 which will contain everything you need to go 3 plug truckside and will also allow you to run a MVP as well as your Ultra.List price is around $510,this is a Fisher part#,I would cross reference it for you but i don't have any Western books in front of me,a Western dealer can probably do it.
    OR
    26345 -straight blade controll harness
    63411-Vehicle Battery cable
    29175-Adapter
    5794k-1 -motor relay
    22111 22" battery cable
    This at list price will run you around $350,again Fisher part#'s but they are both the same parts

    now, is the part numbers after OR to change his plow side? or is that a cheaper way to change the truck side to fit a 2 plug unimount?
