Just to advise, the led strip does fix to the DD cage underside itself, not to the climate unit, it does have a plastic trim that fixes over it with a clear strip for the light to emit through to give it a nice ambience as such & usually the wires would be fed from behind as with the rest of the climate, radio, buttons etc, just tag ionto an existing interior light led eg. ashtray which if you dont have, you may find a tail still sitting there where ashtray would be incase of one fitted, has 2 pin connector on end.
