Help request for vacuum line connection
Condensed version: Had a shop do a cam install for me back in 2019 and it ran great up until the EBCM shorted and caught fire later that year.
Car sat from then until now while i spliced in a new EBCM harness and ABS pump. Anyway it miraculously started with a couple Gal's of new gas and some sea foam, but while tracing MAF sensors codes I found what looks like three unconnected vac lines the shop never hooked up. This is on the drivers side and runs just under the fuel rail. The front plumbs into the intake before the throttle body. In the rear there's a rubber elbow (middle arrow) that looks like it hooks up to a rigid line (right arrow) near the oil pressure sensor. Any idea what hooks up to the line that runs under the fuel rail (Left arrow in my pic)?

I think you are talking about the EVAP purge line. Should go from intake to purge solenoid, then to the line running to the back of the car. usually a test port on that line also. Looks like the 97-98 cars have a different setup than the newer stuff.
