    Ok I have done a search and still have not found exactly what I am looking for, With that said, on my 2000 chevy NBS 2500 I am looking at putting a 8ft unimount on for now, however, in the future I would like to go to a ultramount. I was looking at going with a ISO module but am not sure witch one I would need, I see some of the 4 ports say they fit a unimount and my year, and the same with the 3 port style. The way I understand I need a 3 port, will a 4 port work? I made some phone calls and got some numbers but they do not seem to match up for a 3 port. what do you think the best option would be? do you have any part numbers for those options? Also looking at something that I could maybe move to a newer year but same style truck if I ever find one I like. I had a relay system on the truck a few years ago but got rid of everything for the truck because I thought I was going to sell it, and the last few years I have just used the other truck so I had no need for my truck, but the other one is on its last leg.

    I have a 2 plug ultramount.You can make ultramounts into two pluggers . All that you have to do it get a hold of a 9 pin plow side harness and change them from 3 pluggers to 2 pluggers. Or just take the lights off your unimount and put them on your ultramount... done.

    I world recommend wiring the truck with the 3 port Iso system now and changing the Uni to three plug to match. Will be cheaper now rather than later and once you do go to a new (or newer) Ultra you'll need no further changes.
