Case 2: Can Box does not support reverse gear

In case the Can-Bus-Box does not deliver +12V to the green wire 6Pin to 8pin cable while
reverse gear is engaged (not all of the vehicles are compatible) an external switch-over signal
of the reverse light will be required. Because of the fact that the reverse light signal is not
free from electronic interferences, a relay (eg. AC-RW-1230 with AC RS5 wiring) or an
interference filter (e.g. AC-PNF-RVC) will be required. The diagram below shows the use of
the relay.
Disconnect green cable of 6pin to 8pin cable near the black 8pin connector .
Isolate short end of the green cable (CAN-Box side).
Connect Reverselight/Power with Coil (85) and Ground (86) to relay.
Connect power of rear view camera and the green cable (Video Interface side) of 6pin
to 8pin cable with relay output (87)
Connect continuous battery current to relay input (87)
2.6.1.3 Video Signal Connection to Rear View Camera
Connect the video-RCA of the after-market rear-view camera to the female RCA port
of the video-interface which is labeled as CAM.
