Review on Voyager 31300006 Camera Connector: 4-pin Female Adapter to RCA Connectors with Power, Ideal for Multi-plexing Systems, Video Recorders, and Digital Recorders by Bob Souza

I only have one backup camera on my van so I didn't need the expensive ASA triple camera connector that is built into these units. The car stereo store told me they needed to replace my camera with one with an RCA connector. I said forget it and bought the Sony Apple Play system. I bought an ASA adapter and installed everything myself. That's great! There are no instructions for installing an ASA adapter. Remember to connect the red wire to power and the black wire to ground as the camera requires power to operate. Plug the yellow connector into your radio's camera port and you're done! I plugged in a white revision wire but it interferes with the regular stereo so I left it unplugged. This hookup saved me over $1500 because I could use a cheaper radio and install it myself.
