Regarding the unconnected red wire, there was a small red wire that was on the end of the RCA end (near the head unit). When I connected it to the 12+ power (in conjunction with the reverse light bulb wiring) the head unit displayed the video all the time - even in park.
My suggestion is if you STILL have problems with that camera after exchanging it, I would just buy it through the guy I bought the camera from. Good think it's a cheap camera!
I got the replacement cam from the ebay seller. I check it while I was in the parking lot. It does turn on instantly now.
Now, on to the chore of water proofing it and re-installing...
Thanks for all the help!
