After-market rear-view camera
Note: Do not forget to set dip5 of the video-interface to ON before testing.
To automatically switch to the rear-view camera input while the reverse gear is engaged, 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.
Disconnect the green cable’s pre-connected male- and female connectors of the
12pin cable and connect the green input cable
“Reverse-IN”
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 the green cable’s female
4mm connector. The output-cable
“Reverse-OUT”
remains disconnected as it’s out of
function.
Connect the Reverse light’s power-cable to coil terminal (85) and the vehicle’s ground
to coil terminal (86) of the relay.
Connect the output terminal (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 terminal (30).
