    I bought a complete used ultramount (6 years old) 3 plug this spring that was on a 98 chevy. I got it blasted and was planning on buying a 6.5 and putting it on it. I ended up getting a hell of a deal on an 03 2500hd so I am going to put the plow on that truck. I know I need a mount but my question is will that harness plug into the silverado or will I have problems? Thanks for any information.

    You will need a new harness. 88-00 aren't the same aside from sealed beam style'd lights, let alone that 03 changed again after the 99-02's b/c the headlights swiched to positive ground. The control harness will work, and if you have some electrical knowledge you can make the light harness work, especially if you used a switch, but it will not plug and play for sure.

    It can be done. If you search I think B&B posted the conversion instructions a couple years ago.
