the first is a blow bye line coming form the exhaust side valve cover
it goes into the intake. if you have the rubber intake theres a hole/tubey thing for it sticking out. if you have an aftermarket intake youl have to have a bung welded/added on.

the second is just a vac line to controll butterfly valves or fuel pressure regulator.

the thrid im not really sure which one your pointing to but most of that is just emmisions stuff

the fourth lil wire thing im not sure from just a pic. pic of where the other end connects?

theres two hoses in the third picture, on long thin one that just connects to the intake on the left side after the throttle, the second is a bigger hose that comes from under the throttle with a T in it. one side seems to connect to the intake on the right side and where the T is one hose goes to underneath the intake left side and the other end of the T is just disconnected thats why im wondering where it goes. hope that makes sense.

As for the wire, it leads somewhere to behind the engine :wtf2:

Any help is appreciated! this ca18s come a long way seeing as i knew nothing about cars period when i started this project, now im addicted :P

I believe i ID the two hoses in the third pic, i dont know what they do butttt i believe the small hose connects to the BOV? and the larger hose connects to the IC piping prior to the throttle? Input is welcome. :bigthumb:

*also stumbled apon the "installing catch can" in the stickies and coincidentally figured out what to do with the hose in the first pic yay

yes the larger hose connects to the ic piping. and the smaller one CAN be used for a bov if you have one..

and ya that first hose pictured is used for a catch can. but if went into the intake from the factory.
