I want to put a worklight on to the Puma but need some information.

Is there a pre-existing harness on passenger's side rear to plug in to?
What's the best way to run a lead from the gutter into the vehicle?
If anyone has a copy of the LR fitting instructions for the OEM Worklight that would probably answer all my questions. I don't see the point in buying a genuine one though, but if anyone can recommend a good robust unit I'm open to suggestions.

Thanks in advance.
