Backstory - I have a 87 240 that was basically stripped so it could be cleaned and put back together just for fun(not really but that doesn't matter). Vacuum line diagram sticker in engine bay doesnt exist anymore either. The car originally had A/C and cruise control. A/C, climate control/the whole air vent system and cruise control are not going back in.

What I desperately need help with - which lines are necessary? It seems to me that a lot of them ran to the heating/ac and cruise control system so with those gone do I just plug them up, redirect them or what? And which vacuum lines are even left after removing those? The only lines I currently have placed are the ones connected to the charcoal canister.

I'm sure you can tell that I'm new to this but if I can strip the car of all its wiring and put it back together then I hopefully will be able to learn how to get these vacuum lines together with some help. Pictures, diagrams, links, anything is helpful. I feel like I've been researching for days and just not finding the info I need. Thank you!

 

you need vacuum to the power brake booster, and to the ignition controller on the front right fender behind the headlight. you need vacuum to the charcoal canister vapor recovery system unless you you remove and bypass that (and then will not pass smog if you live where 87's are still smogged). if you've completely gutted the airbox behind the dash, so no heater, no fan, no ventilation, then you don't need any vacuum to the ventilation controls. unused vacuums can be capped off.

edit: oh, the brake booster vacuum is the larger diameter nipple on the manifold, and it should have a 1-way valve in it (a little black and white disk in the middle of the hose, usually).
