basically the only vacuum lines you need are the ones going to map sensor, fuel pressure regulator, and fuel atomizer port, and wastegate lines if turbo. Keep the coolant lines going to the thermowax if you dont want to have to throttle it to keep it idling when cold, but vacuum lines not needed. BAC not needed if you dont have a/c, else just jack up your idle a little if you want to lose the BAC
