I thought there was four to start with on the fire wall. Two come off the diafram mounted on the housing unit(fan) One come off the intake for vacume for the system(DK blue?) and the last was off the suction valve to activate the AC. mounted to the switch behind the glove box.
I hope this will help you a little,
I have not been able to get any of my vents working right,
PM if you need any scans from the manuals
