Cam-VIN is your reverse camera in most likely. It will show when you give the reverse pin 12v and thereby activate the reverse camera app (or open the f-cam app and switch to rear view mode via the button on the screen).
Aux vin is what the AVIN app shows, and is not tied to any power pin as far as I know.
F-cam in is separate from those two and the connector isn’t always present on all units. You might have the f-cam in pin on a second AV connector that doesn’t have any plugs included for it (for instance on my unit f-cam in is on a small 8 pin connector next to my main av connector which I had to make my own cables for)
Check the front parking camera mod thread on here, I posted pictures of what my Witson unit looks like.
Thank you so much!
I've checked the other thread and I may be in luck with the 8 pin connector.
Mine's also a Witson unit: http://www.witson.com/en/displayprod...roID=102131570
I don't have a photo of the actual unit in my car, but according to Witson's product photo it does have the 8-pin connector:
I currently have my reverse camera connected to CAM VIN (video signal, yellow RCA) and the +12V to the brown REVERSE wire on the main ISO harness.
That brown REVERSE wire gets +12V when I manually change gear to the reverse gear (otherwise it's at 0V, I've measured it), but clicking the reverse camera button in F-Cam doesn't get me +12V on that wire.
If I understand correctly, you have both your front view camera and your reverse camera connected to the red CAM POW wire on the AV-harness?
Does the radio output +12V on the red CAM POW wire when you manually change gear to the reverse gear AND when clicking the reverse camera button in F-Cam?
If so, I'll have to change the wiring.
As for the 8-pin connector: what is it called and where can I order the correct harness?
Thanks again for all the useful info!!!
