Passenger side. The two connectors in front of the speaker are for door lock and window switches. The connector just below the yellow X is for the three button seat memory control. These speakers where in GREAT shape and were removed from a 2006 SC430 and purchased from a salvage yard I found on eBay. They were $80 each, shipped. I negotiated the price. Most, if not all people WILL negotists on eBay.
