the vacumme line comin g from the engine should be a hard black plastic line with a black rubber elbow. I have not seen a non-auto climate controller so I can't con firm exactly where it goes. but it should enter a wiring harness that passes through the firewall, check for vacumme here. You will probabaly have to look from under the glovebox on the passanger's side. The port on the engine should be one of the tees on top of the supercharger. (unsure about 97's 98+ are tied in beside the brake booster vacumme.)
