I had a mad idea to put in some blue LED ambient lighting in the rear light fittings. I've already squeezed some blue LEDs into the centre lights. I thought I could easily draw some power from the rear heater control panel which lights up with the ignition which would be ideal but I can't get the panel off to look at the wiring. I can release one side but then it seems to be pulling the whole casing down so I'm scared of breaking it. Any ideas or has anyone done anything similar (and easy)? Even if I could would I be able to find a way through the headlining to reach a cable to the rear lights. I'd also like to put a light in the inside of the (huge) tailgate as some cars have to help with loading outside. Would this be easy to do (again, probably have to take of the tailgate inside trim).
Thanks
