Help With RVC Wiring In New T5.2 Multi

[husky]

Hoping someone can help with wiring a genuine VW camera to a new multi. I need to connect the ground, Reverse +ve and 12V +ve somewhere. I was thinking of the following connections:
Gounding to the bolts in the tail gate
Joining the power and reverse power cables together and connecting to the reverse light wire.

I have taken the tail light assembly out and there are 5 wires in a connector with 1,2,3,4,5,6 pins. I have tried putting the van in reverse and using a multimeter to identify the reverse wire however they all show 12v which doesn't seem right. When I take it out of reverse none show 12V. Can someone assist with identifying these pins or offering an alternative location to wire back to?

I have also tried to test the camera after connecting to the RNS510 and nothing shows. Does it need coding before it will display the image?

cheers,

If its a factory radio then I would imagine that yes it will need coding . Earthing to the body is fine , some other members will be able to help with the rest of the wiring for you shortly .

Think I have it sussed. Looks like black is ground and green is the +ve for reverse. Does this sound right to anyone who has done it?
Is there a better place to pick up reverse and power?

Sorry I can't help if it was an aftermarket I could give you the wiring but as its a factory its all integrated through Can Bus , you may have to wait , If you connect into a circuit that's not suitable you may cause the on board Computer to play up . When I fit aftermarket its simple connect the RCA cable to the unit connect earth to ground and then just connect the power wire to a 12 v when ignition is on which is actually part of the aftermarket head units they have a dedicated wire just for this function not sure about the factory . From memory some posters have found spare fuse points under the front passengers seat . But again it would be worth waiting for someone who has done it with factory parts etc as it will need coding .

Some light assemblies just have one color for all wires (maybe white or black),
follow those wires back to the plug and socket connector and look for -
(gn/sw in wiring diagram) - green / black - reverse light -
(br in wiring diagram) - brown -ground -
plain brown (no trace) is usually universally ground on most if not all VWs.
Be careful when testing not to apply 12V to just any connector - Risk of module damage.

When I fitted and wired our towbar I found the signals in plugs up in the roof behind the roof trim .

Yes, if a genuine VW camera it should have the wiring and the connector ready to connect
to the coupling station (connector) in the tailgate (rear lid) LH side IIRC.
