looking though my engine bay i found this unpluged and i am wondering what i need to connect it to and what it is











this is right behind the airbox on the left side if u didn't know

 

pressure sensor..

should have a vacuum hose that tees to the acv and air bypass

and an electrical connector..



the blue wire looks like a ground connection...

 

yah that blue wire isnt factory

 

if you have a t2 its for your boost pressure sensor

 

NA's have them also.



Although I dont know what N327 would be...

Whatever it is, it doesnt look anything like my factory pressure sensor ( though mine was for a T2... )

But, like people said, it should have a vacuum hose going into it ( one that carries manfiold pressure/vacuum ) and a electrical connector. Both would connect to the underside of the sensor.







EDIT: After looking through the FSM, I dont think it matter if its plugged to the ACV. It looks like hookng it up to any nipple that see manifold pressure will work.

 

n326/n327= 86-88 na

n318/n319/n332 = 86-88 t2
