For example on cars conforming fo a North American specification which prohibits the fining of rear fog lamps. the appropriate relay will be omitted. The relays ere positioned in groups. Access to ?he relay group on the driveis side of the car (interior nrlrys) requires tht removal of the knee roll trim.
