this is DEF your driver side multiplexer...some things you need to know. number one, you must match it up by year and trim level...contrary to some belief it does not matter if its from a two or four door. if your car is a 98-99 you must use a multi- from those years...an EX multi- will work for an ex or lx, but not visa-versa!!! do not try one from a 2000-2002, they are not the same!!!! goto a pick it urself junkyard and if your lucky enough to fing a compatible car, pull out the fusebox on drivers side and remove the little plastic box, this is the multiplexer...ive gotten them free that way cause it looks like nothing that way. oh yeah, there's a stamping on the box that says either S82 or S84...this must match your original too. good luck, peace.
