Hey guys just got a mechanic to plumb my zzw30 engine up due to lack of time with work to do it myself and putting it the intake and exhaust in I've ran into 2 problems firstly what is this sensor and what hoses connect I've found the electrical plug just need to hook the hoses in!


Also how far along the loom is the right o2 sensor plug?

So I found its a vacuum sensor valve what hoses does it go to?

usually to a nipple on the intake manifold somewhere, sorry i dont know exactly where as im not familiar with this engine.

That valve might have something to do with the emissions control system. One of the nipples might connect to the charcoal canister and the other the inlet manifold or something.
 
I have no idea really, never looked at a spyder engine before. 

Yeah google up the ZZW30 vacuum diagram or find the BGB and it should have it there.
