Chrysler Repair: Vacuum heater control, vacuum control, self destruct

Question
you gave information on the heater control for a 85 Fifth Ave. I have a 88 with the same problem!! Looking at the end of the vacuum extension harness after it is un plugged what is the numbering pattern. The connectors self destruct and there isn't enough left to tell.

Thank you
Ed

Answer
Hi Ed,
I checked the '85, '87, and '89 and they appear to be identical assignments to the vacuum control. The only minor difference is that #4 which was in '85 shown as "sealed" with a small hose of no color given while in the latter years it is just shown with nothing at all attached to it.
Sorry I don't happen to have the '88 but it would be the same too.
