Here's a bunch of info on my weekend project, a pretty cheap Backup Camera Install. ( thanks sam_i02 and others for feedback and help ) I wired to red, so I can switch this on/off at will by switch to my AV Input on my head unit as desired. I also setup a female molex plug, so I can easily detach this camera, but more importantly hook up anything with minimal effort. Overall, this project was a smashing success considering it just costed time and about $50 for product.
Cabling FYI: I did run all 3 ( Video, Power, Ground ) all the way into the Cab, up through the plug underneath the driver's seat and into the kick panel in my 2k6 4 door. I ground to a location under the driver pedals, and soldered an in-line 1 amp glass fuse covered in heat shrink in case the camera gets feisty. Basically, I just followed the exact path of my dynolock tailgate cables which was a very similar project.
