thanks for that, i will check all of those. on another note, when i first encountered this issue i did move the H/U ground from the factory harness to a spot under the passenger carpet. also i moved the piece of 1/0 ground in the back from one of my hitch bolts that was ground down, it was sandwiched between the hitch and the frame, to a hole that i drilled and put a 1/2" bolt through. neither worked but i will move them again. and deff try disconecting the illumination.
