I recently purchased an 87 Trans Am with a 5.7 TPI. Vacuum lines are all messed up, so I'm in the process of getting them corrected. One question I have relates to the lines that connect to the EGR solenoid. One the back of the solenoid, there's 2 ports (see red circles in picture) and I'm not sure what lines, if any, connect to these. Wondering if anyone can provide clarity on this? Back of EGR Solenoid

Top port goes to EGR
Bottom port goes underneath throttle body.
