need help after new engine install... where does this go...
ok so its been a really long time since i started tearing down the camaro for the motor swap, well it fired up last night and yes im very happy
however its been so long there is some misc wiring im not sure where it goes, and for the life of me i dont know where all the hard plastic vac lines i took off are, so i bought some vac tubing, 90 degree bends and ends to make my own but i need to know what goes where
can anyone get me pictures of how the vac lines, emissions control tubing crap (like from engine to charcol canister, pcv ect) and how some pics of what bolts go where on where the upper intake bolts to the runners
as far as vac lines go iv looked at diagrams, pics would be best
thanks to all here at TGO i want to get this taken care of asap, its whats keeping me from getting it out of the driveway for a test run
ALSO i need pics of how all the heater hoses go, from fire wall to where? and on the throttle body, what the 2 big size vac ports are on the passenger side of the throttle body, the ones on the pass side rear of the upper intake, , pretty much everything from the lower intake up
i did get it together enough to hear it start, capped off what i havnt figured out so it would idle
SIDE NOTE: the car no longer has the smog pump and related parts so im sure some of the wiring may have went to that but im not sure i have a few plugs in that area im not sure of and a few on the driver side. ill post pics of the wiring in question tomorow night

Re: need help after new engine install... where does this go...
It's fun to play detective, but yes, more details would get better answers. Verbal description is TPI, username is 1990 Camaro.
The vacuum port on the bottom of the throttle body goes to the EGR solenoid, other port on the solenoid goes to the valve. There are two ports on the passenger side of the TB. Small one is for vacuum purge, large one is fresh air supply to rocker cover on bank 2.

that fresh air supply would go to the rear of the passenger side valve cover correct? now i dont have the original valve covers... they went with the old heads, the bottom end was an 87 so i had a set of 85 heads redone, im using chrome summit valve covers.
would it be okay to cap off that fresh air port? put a small filter on it? thus retaining the breather cap i have on the valve cover? or do i need to run a line from that port to the valve cover

I would use the fresh air port because it's already been cleaned by the engine air filter, and more importantly, the air has already been metered by the MAF. If you plug it and use a breather, the MAF reading will be incorrect.
