I wanna get thefront fog light covers to be taken out and foglight be installed. the problem that I am sitting with is that the E90 320I is not pre-wired, meaning there is no available connection made availabe when I look under the front bumper. I nderstand that I need to get the Foglights kit, that is the physical lights with housings, Ballasts, wiring harness, OEM Headlamp Control switch with rear and front foglights buttons and relays. The question that remain unanswered is: How do I gonna do the full wiring of these items as listed above?
