Another reversing camera question

[Sandgroper]

G'day all,
Can anyone tell which wires to wire a reversing camera to in the dash of a 2012 puma? I've read here how people have wired them up so they can flick a switch and see what's going on behind them when they are travelling forward and I'd like to do the same instead of wiring it through the reversing light which would mean it would only work when the vehicle was in reverse. It looks like multi colored spaghetti in there to me and I've no idea which wires to splice into. Thanks in advance for any replies, any help will be greatly appreciated.
Cheers,
Dave.

Might be easier to go to the top of the gearbox and take a feed off the reverse light switch lines themselves. On my 95 deefer they are easy to get too, can't remember if its under the cubby box or the transmission tunnel, I think the later though.
When I do my camera I will take a feed off both sides of the reverse switch and run these into the two sides of a double throw switch. That way can select auto screen on or manual on all the time.
