So while I'm going to have to relocate my camera regardless (rear tire will be in the way) I was thinking about the possibility of upgrading the camera in the process.

Ideally i'd like to leave the OEM camera where it is, unplug it and use one of these:
TaoTronics TT-CC17 Camera

.. Just need to figure out how to tie into the existing wiring, assuming it puts out the proper signal.

Anyone look into this yet? And/or any members with more of an electrical background have any advice? I'll have to dig through my service manual to see if I can get an idea of the video type and control for the OEM setup and maybe look at the manufacturer specs for the aftermarket options.

I'm surprised this hasn't come up yet either; i guess no ones had the stock backup camera go bad? It's really expensive compared to aftermarket options.
