After my wife got into an accident and the person-at-fault's insurance told us that pictures were not enough proof to prove guilt, they just showed that there is damage, we bought a camera for her Jeep and one for my G/T. I hooked up the front cameras, and was going to wait until warmer weather to do the back but I am not a fan of how the rear camera looks.
I was going to start a new thread for this, but seems that there is some interest here-
I ended up getting an AlphaOBD (and all that equipment for the TTPMS & TBC mods) and I saw a thread about installing a cargo camera. That made me think about if the 8-pin harness from the fitcam. If it can be mapped, could it work with the camera in the cargo light (from another thread on here), and I can have a cargo camera to watch my trailer at the optimal angle on the 12"
and have a recorded back camera that looks oem? I might just drive in reverse everywhere.
I found a post on a Toyota Rav4 forum that shows the pins from the manufacture- Props to that OP.
I picked up an 8-pin extension to sacrifice/ use for connecting to the camera to the 8-pin, which will let me map the wire color to the pin using a voltmeter. Since the fitcam camera has a microphone (maybe not the back camera, but still uses the same 8-pin harness), it is a guess between RX and SL for video signal. I'm thinking R is for record or something and S could be for sound. I take it that N is for neutral, P for positive.
That's where my knowledge of this topic ends for now. I do like the scientific method of finding out, but it risks bricking the brain and I'm not rich enough for that. Is there another test that could be done outside of the unit that can show us which pin to use? Maybe if enough of us ask one of these youtubers to sacrifice a unit for science, we can have an answer and another mod we can do.
