Hey guys, I am currently doing an engine swap on my Buddies '95 Impreza wagon. I have most of everything done already, but I have one thing I can't figure out. There is some sort of sensor, and or valve that attaches to the back of the #3 cylinder intake runner, it has a vacuum line that runs to the top of #3 intake runner, into a port, so, that's all good... BUT I don't know where the other line goes, I tried searching for a line on the car, and on the old engine, and found nothing that looked right. So any idea where it goes?

 

Just for some more information here is whats going on. the Engine that came out of the car is a stock 1.8L, and the one going in to the car has a '98 or '99 2.5L block with '96 2.2L heads, with a '93 1.8L intake. The block and heads are no big deal, but apparently there are slight differences in the '93, and the '95 intakes, So I have had to swap the engine harness, a sensor for the EGR, and this one other sensor. Like I said I can't find anything that leads me to where this goes, so any input would be great. 

 

Thanks for any input guys!

you could dig around at www.opposedforces.com , but maybe someone else will reply with experience on this.

It's for the monitoring system for the EGR valve. There's a couple different sensors mounted to the passenger strut tower that the vacuum line runs to.

Well hopefully it will make some sense in the vehicle. I'm not going to go crazy over it, I just can't for the life of me figure it out. but honestly if that's my only problem so far, I would say I'm doing pretty good, lol.
