Outer Limits 4x4 Board

I'm about to put a rear work light on the back of my 4B and am trying to figure out how to get power to the outside of the rear door without drilling holes in the panel.

Those of you who have already done this, how have you done it?

GO via the floor or even via the engine bay, if your keen

Route the wiring where your rear numberplate light wiring goes if its in a suitable location.

Thanks for the replys guys.

I eventually drilled a hole through the spare wheel mount and ran it through where you couldn't see it.
