Case 2: CAN-box does not receive the reverse gear signal
If the CAN-bus interface does not d12V on the green wire of the 6pin to 12pin 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 signal contains electronic
interference, a traditional open relay (e.g AC-RW-1230 with wiring AC-RS5) or filter (e.g. AC-
PNF-RVC) is required. Below schema shows the use of a relay (normally open).
Cut the green cable of the 6pin to 12pin cable close to the black 12pin connector.
Isolate the short end of the green wire (CAN-box side).
Connect the reverse gear light signal/power to coil (85) and ground to coil (86) of
relay.
Connect the rear-view camera power wire and the green wire (video interface side)
of 6pin to 12pin cable both to output (87) of the relay.
Connect permanent battery power to input (30) of relay.
