Reversing light feed for camera

wheelnut · Aug 2nd, 2022, 19:37

Hi.
I have installed an aftermarket reversing camera (separate screen) and wireless kit to my 2016 XC60 today. It works well with an ignition controlled live, but I couldn’t figure out where to get a power feed from the reversing lights from.
When the reversing light live to the bulb is used, it does not give enough power .3v.
The same with the reversing light feed on the towbar.
Where has anyone else taken the feed from.
I know I can wire it in with a manual switch and it will work fine, but would prefer automatic operation.

I think your only option is to wire in a relay fed from the reversing light circuit

If the reversing light bulb is only getting .3v then does it illuminate at all?

When the connector is disconnected, the pink wire shows 13.89v.
When I connect it to the bulb, it lights perfectly but the pink wire only .04v.

The two tone green wire shows 12.75v, whether connected or not.

The wireless transmitter seems to need a higher voltage to run. If I connect it to a permanent live in the auxiliary fuse panel at the side of the boot, it shows 14.23 v and works a treat.

I have to confess I don’t understand canbus.
