Jorn,

The vacuum tri connector I'm talking is the one that connects the vacuum supply to the vacuum valve mounted on the IP and the transmission. It has a restriction in the lead going to the vacuum supply which alloaws the vacuum valve to vary the vacuum to the transmission depending on the position of the throttle.

This connector looks like he one in the pictures but should have a plastic clip on the lead that has the restriction inside it.

This is only applicable to cars with auto transmission.
