ok you have to take your breather box off with to or three bolts i think 10mm and then the intake tube going to throttle body with a screw driver loosen the clamp that it holds to the throttle body then you should see a round black top about 2 inches around three inches tall with an electrical plugin just under your top radiator hose on the intake or you thermostat housing that is it ..it is bolted with two bolts to the intake i think they are 10mm bolts you will need a ratchet with a long extension and them bolts will be tight so make sure to have your socket on the bolt good or it will strip it out so make sure not to drop them bolts you might loose them...note if it is not working it might just need cleaned good with brake cleaner there will be an open hole and a hole with a star bit shape head on it that is supposed to move in up and down if it does not move then clean it by spraying brake cleaner in the open hole and might have to get a small flat head or something to loosen all the carbon build up this might help you from buying a new one
