what is this?

 

i was going to swap a throttle body onto my engine (from a 01 forester, my motor is from a 00 Outback that was an automatic) with a dialed in TPS, but it doesnt have the hose barb for the hose that leads to this sensor. do i even need it?

i think thats about how it went. :-p

Have tried useing the late model wire harness in older car they do not like it and had runability ishures and cuting out and default problems it needs its dash and other ecus to work properly I had to use the 91-94 legacy harness on the newer engine to get it to make power and run right

other than a little bit of a leaky headgasket, the things running pretty good, its not perfect. but it always gets me from here to there. the only problem i get now is that when i go to start it, i turn it over for a while and it doesnt start, but then i get off the starter, hit it again and it start instantly. i dont know if thats related to a vacuum leak somewhere, IAC sticky, maybe my alternator is wired wrong even tho the voltage is fine (14.2v) output. maybe im not exciting the alternator when i turn on the ign? who knows. lol.
