Case 2: Interface does not receive any reverse gear signal
If the video interface does not d12V on the green wire of the 20pin cable when
reverse gear is engaged (not all vehicles are compatible), an external switching signal from
the reverse gear light is required. As the reverse gear light’s power supply isn’t voltage-
stable all the time, an ordinary open relay (e.g. AC-RW-1230 with wiring AC-RS5) or filter
(e.g. AC-PNF-RVC) is required. The diagram below shows the connection type of the relay.
Cut through the 6pin Power / CAN cable’s green cable and connect the one side
which is near to the 6pin Power /CAN connector to the output connector (87) of the
relay.
Note:
Not least to avoid short circuits, the best solution should be, to crimp a male
4mm connector to the relay’s output cable and connect it to a green cable’s crimped
female 4mm connector. The remaining opposite part of the green cable remains
disconnected and should be isolated.
Connect the Reverse light’s power-cable to coil (85) and the vehicle’s ground to coil
(86) of the relay.
Additionally connect the output connector (87) of the relay to the rear-view camera’s
power-cable, like you did it to the green “Reverse-IN” cable before.
Connect permanent power / 12V to the relay’s input connector (30).
