I bought the light bar and harness from a member, the plug portion that hooks up near the spine is missing so i have three wires there. I am pretty sure i can just cut off the end attached to the bike and put different plugs on there to match them up but was not sure if there was any special thing about the OEM plugs, (fuse inside or something like that) the relay portion etc is all there and good. So can i just hook the wires up that match on both ends?
