I have a Lexus oem camera in which 4 wires terminate into 4 pins inside a grey plug as shown in these photos: https://plus.google.com/photos/107427309110071106739/albums/5748791403027681857?authkey=CL3ckpC-rqjIAQThe Amazon harness is made for the SE and other vehicles where the back up harness is connected to the radio, and is terminated under the console. You plug the [Amazon] harness to the connector under the console, and then the Camera cable will connect to this. Very little wiring to do.
The LE like mine, does NOT have the harness under the console. I had to fab up a harness. The vehicles with NAV and no camera, may have the console harness.
The camera is activated from the body computer [when you connect the wiring]. You do not need to attach any wiring to the back up lamps or harness. [see my previous posts]
My plan was to connect the Amazon harness to the connector under the center console. The Amazon harness terminates into an RCA video female connector (or that's what it looks like): http://www.beatsonicusa.com/stereo/beat-sonic-bc5-rear-camera-input-vision-selector-harness.html
So my plan was to splice the yellow wire inside the grey plug and an RCA video male, then run it to the front where the Amazon harness is.
My plan doesn't sound right because the camera isn't being triggered on. I feel like it is just carrying the video signal to the front, which isn't possible without power. At the same time, I don't have the harness on hand so I'm not exactly sure what it terminates to (harness ships from Japan).
Thanks for any input! Also, I'm a beginner with electrical wiring so that's probably why I'm a little confused.
