I have a Western Unimount on my 1999 Chevy Suburban. The Truck is pretty used up and want to swap the plow onto my 2003 Chevy Tahoe. The research I've done tell me that the frames are the same but I am looking for confirmation. Will my set up transfer over? I will probably wire the lights separate from the truck harness and onto a toggle switch if the wiring won't match up.
