RE: Reverse lights not working
I know there was a problem with the flash on the "Totally Integrated Power Module" (TIPM) with stop and turn lights but I don't remember anything about back-up lights. (And I don't have a wiring diagram handy to check) They took out the fuses and ran everything through "computer controlled" relays. So, when it saw a large load it cut out the circuit. After a few tries it became a permanent problem that required a reflash to fix. One way to solve that problem is to go into the harness before the trailier connector and put in fuses on all of the leads (except the ground, of course) That way the worst you'll have is a blown fuse and won't require a re-flash.
