Can somebody give me the pinouts for the large connector on the back of the climate control?

I'm having intermittent problems with the AC. It works first thing in the morning, but after the car has been hot for a while it won't come on,

An enthusiastic wack on a knob or two (not always the same one) will generally make the unit kick on. the temp knob seems to work ok even if the AC is off, the fan continues to work.

I'm thinking that its either the AC on/off switch in the vac module or the board it's self or possibly the connector.

Appreciate any thoughts. My manual (Haynes) the wiring diagrams are hard to figure out!
