I orderd the harness and 3 lights. 4 different part numbers. Im currently banned at the other site. But if you serach rgullette83's thread the lights and the harness number for a bald roof are in there. You do have to swap the wires in the plug though (where it plugs into the passenger side fuse panel), because the positive and negative taps are swapped in the 900 platform. Theres alot of good info in his thread. Then I used Floriduramax1's measurements for the lights. If use different measurements beware of the cab support.
