hello guys, I recently replaced all the vacuum fittings under the hood, new fuel filters and an air filter, and I also replaced a sensor which is mounted on the firewall in front of the driver. The car was hesitating at speed and I was told to bypass this and it worked. But I have replaced it and I only have two vacuum lines to connect to it and there are three nozzles. There is one on the bottom which I have connected to the sensor on the intake right over the #3 cylinder, the connection on the front of the sensor runs down the the IP and there is a connection on top of the sensor which was broken off the previous one. I have no idea what should be connected to this nozzle.

The car runs better but feels as though it is starving for fuel alittle around 80mph. If someone with an 86 300sdl can pop their hood for me to let me know where the vacuum lines are supposed to go I would really appreciate it. Thanks for the help in the past with my car, and thank you ahead of time.
