Usually there is only one vacuum line that goes through the firewall. Look for a vacuum tee on the firewall. I'd have to look at it. Just find anything that has a vacuum line and follow the line. Your cruise control may have a vacuum line, your map sensor, Your fuel pressure regulator probably has a vacuum line. The throttle-body may have vacuum lines going to it.
