Help wiring Teyes CC3
 

Hi everyone,

I recently received the Teyes CC3 to put into my 2013 Corolla, and although I have looked everywhere, I can't seem to find information on two issues.

I am trying to wire the OEM camera to the unit, and I have the camera powered and working but I cannot figure out where to connect the reverse wire to have the car switch to the camera when I put the car in reverse. Most diagrams online have a third yellow wire coming out, but mine only has black and red.

Secondly, I have two sets of buttons on my steering wheel, but only one side is working. I am assuming I have "key 1" plugged in, but not "key 2" but I honestly have no idea if that's actually the case. There's one part of the harness that does not connect to anything, and I'm speculating this might be the missing component, but I'm unsure of where I'd plug it in.

I also have some cables that don't connect to anything, it looks like the grey one goes to the OEM AUX/USB, I'm assuming the second is for the OEM GPS antenna, but I have no idea what the third cable is for.

Any pointers would be greatly appreciated!

I added some pictures here for reference, I can get more if needed: https://imgur.com/a/xm7m1Ek
