Default vacumm line question

i'm in the process of doing a single to dual cam swap and i have 4 loose vac lines coming out from underneath my throttle body, can anyone tell me where these lines go? 1 runs to a plastic t and has a second line coming off of that. and 1 is a larger diameter then the other three.

any help would be appreciated

Cap all of them off unless you want to keep emissions crap. You just need one line from the back of the intake manifold to go to the fuel pressure regulator. That's it.

they can be capped if you remove your emissions crap.
my suggestion, take the intake manifold off so you can follow the lines and what not and completely remove what isn't needed. and cap things off better. less risk of mistakes that way... or at least it was for me....

have fun
