hi everyone, this is my first post. i bought my rx7 a few months ago for 200 bucks. i figured it was a good deal because i can make a profit no matter what happens. but anyways, there are some vacuum ports or something( i have no idea what they are) and they have tubes missing. i have no idea where they are supposed to connect to. so where are they supposed to connect? i will post pictures. thank you in advance
