Mark, Per Jon's suggestion you should find a backup light terminal on the forward terminal panel beneath the driver's seat. On my '98 chassis it is terminal #39 "From Transmission Module" (check voltage). For simplicity and utility however you might consider attaching the backup wire to a simple toggle switch next to the monitor to activate the backup camera. You can use any convenient 12v source in the instrument panel to accomplish this.

Your current back up camera should already receive a reverse signal, but if it does not and you cannot tap into it there then I do stick with my concern about tapping into the key pad wiring and instead look for the circuit Brina mantions. Prevost is very good about keeping circuit numbers the same so his information should apply to your coach.
