BIGRED - The elect connector I'm referring to is on fender drivers side, tied into a vac transducer (I think) that converts a signal into vacuum for the EGR and RECIRC valve on turbo. Anyway, the click happens here and it definitely causes the vac to the trans line to drop (RAPID JUMP) down to around 10 inches, then it immediately jumps back up - not a gradual release of vacuum as I thought it should be - or am I missing something. I will test modulator for vac, and drive with it plugged. Thanks.
