I think that's what the OP wants to know. Is the wiring in place for Safari lights in vehicles not equipped with them. If it is, how and where does it come through the roof. I believe the intention is to retrofit roof bar or similar. I may of course be totally wrong, as has been known before. 😜The airbags are not attached do the covers.
If you have the set, then wiring is not the problem anymore.
Some wiring is there. I hooked my led bar to rooflamp relay. The relay gets the singal from the high beams, Led bars are allowed to operate the same way.
