    What he means is/ if you can find the right wiring and relays for a newer truck like you have. I'm not sure if they make the OLD wiring that will turn your truck head light on and turn your plow lights on. You can make the plow work with no problem at all if thats what would make you happy, but the light lights will be a problem.

    Also why in the work are you looking to go back in time on wiring? The new ISO is so much better. The old relays are gone

    You posted a thread already

    If your looking to setup your truck.Buy a 3 plug truckside setup.4 port isolation module 27781 green label. Look on ebay I saw a complete wiring setup except controller for $395 buy it now price.

    If you have a or are thinking of buying a 2 plug your going to need to convert it to a 3 plug for it to fit your 3 plug truck.
    26347-11 pin harness
    26359-3 pin control harness

    Like Lone said the isolation module are better then the relay systems.The isolation module is relays in a water tight box.

    Or, if you really want that 2-plug, you can convert it to 3 plug, like chevyzrule810 said.

    Of course the 99 is sitting in my driveway with the plow on because it hasn't been started or needed since January.
