Got the dash all back together now with deck and rear view camera installed, as well as the runs of wiring to the rear. I wound up using a relay to reverse polarity from the remote lead to trick the dvd player into thinking I am always in park I also installed a switch in one of the spare dash pop-outs which switches the rear-view camera on and off, rather than having to be in reverse. I went for a cruise and was surprised how wide the camera angle is. Really helps with that big blind spot. . .
As we often say around here: Pics or it didn't happen!
