i put a b16a1 in my 89 crx hf. i don't know how to conect the vacume lines. there are 4 running off the map sensor assembly on the fire wall and only 2 on the intake manifold and i know one goes to the black canister on the fire wall. how do i hook up the other 3 and which one goes to the throttle body? can someone please post pics or a diagram that has a b16a1 in a crx hf.
