I have a 96 ek hatch with a b18c jdm integra type r motor that I picked up. I have everything pretty much figured out but there is one random vaccum line on the back right hand side of the intake manifold that I have no idea what it goes to. Its not very long, and wasn't hooked up when I got the car. wondering if that was something strictly for the car the motor was intended for, or just something I'm blindly missing. Ill post picture when I get home later today. Also a bunch of wiring connectors I'll try to get picutres of them too.

 

pics for sure.
if the motor runs fine. yank off that line and cap it. theres alot of vacuum hoses you dont need

 

Note: Also, when capped, brings idle down from ~2000 to about 1100, so I'm probably just gonna cap it off

 

its for evap purge selenoid (aka emissions bs)
cap it off and you wont have any issues.

 

cool. thanks for the info.
