Reversing camera - ground connection?

[Fredanz]

Hi folks,
I've fitted a wireless reversing camera in a through-the-bumper config which works fine for my '98 Freda. However, although it works ok I've realised that I have powered the camera incorrectly. It's currently bridging one of the reversing lights (giving it a barely adequate 8-9V to play with) instead of taking a feed from the +12 line to the lamp and running between it and ground.

Can anyone suggest an easy GND source available at or near the rear light cluster so I can do it properly?

(I'd previously tried wiring it in series with the reversing light instead of in parallel as it is now; however, it turned out that meant the reversing light itself didn't work, so it's not an option).

For those interested, this is the camera I'm using: http://www.banggood.com/Car-Wireless-IR ... 95362.html - about 24 quid in your money, quality of feed is just adequate i.e. usable but not high res.

Thanks!

From memory! And it's about 5 years

Used the seatbelt bolt. It's huge and welded directly into the chassis.

Theirs one low down near the light cluster. With care can pull back the trim and hide the wires behind

Many thanks! Will take a look.
