June 4, 20178 yr I recently bought a WRX SL 2.5 UK Spec on auction. It has been swapped with a EJ20 motor, not sure what one (guessing it's the 205). I have a a few sensors and wires that are not connected and would appreciate it if you guys could help me out. This is the first connector that I don't know what it was/should be used for. It is located by the battery. This is another sensor that is located towards the front of the engine by the oil cap. I also have this weird contraption just above their air filter, I have no clue what it is. And the final plug is this pink one. And I have a picture of the engine if that helps.
June 5, 20178 yr Not sure about all the plugs but that thing by the airbox looks like a 2port boost solenoid and i don't think it should be held on with a cable tie lol it should bolt on to a bracket around that area 👍

What is the point of a boost solenoid?
June 5, 20178 yr Yep boost solenoid controls the boost via vaccum lines attached to the turbo outlet ,wastegate and inlet/intake . The plug by the battery looks like a classic (pre 2000) icv (idle control valve ) ive never worked on anything but classics so unsure if it needs to be plugged in on yours . The sensor by the oil filler is a classic cam position sensor . If not plugged in on a classic it won't start or will go into limp mode if faulty . No idea what the pink plug is for im afraid . If the engine loom is newage (2000 onwards) the plug by the battery might be for a newage cam sensor ? Does it run ? P.s had a second look at the plug by the battery and it could be aircon plug ? Maybe 1 of the newage boys would know for sure
