Like Ed said.
It has to be part of the harness. I looked again and didn't find anything.
Malcolm, it was very nice here today, +2 c.
But I'm sure winter's not over yet. We had quite a cold one here too this year.
Can't wait for warmer weather...

And here I thought you Canucks were a bit tougher than to let a little thing like -15c stop you. 
Thanks for giving it a try Malcom.
Ed,
If you look at PET for the 944 a lot of the harness connectors are listed there. However, the pics aren't clear enough to determine which plug is the one in question.
John,
I can't take credit for the CTO bit. Someone here on Rennlist coined the term long ago.
Thanks all
Mike

no worries guys.....there are many numbers on the part and can tell its a VDO #
Bertrand.....cant wait now, winter has been long again.......I was in Vancouver a few weeks ago so had a little taste of warmer climes
Hopefully someone with better digi pic skills than I can clear up the image and read the numbers.

And I can't help but thank you guys for all of the great info on this! Now I know what was done and why it's not there...and that my repairs didn't screw anything up! Got the expansion tank back in, coolant, and fired her up in between polar vortexes. After a few minutes she got her singing voice again. Can't drive her though since the potholes here may swallow her up.

Can you post any numbers from the connector? I've been trying to determine a part number without success.
The pressure switch was first installed in MY1984. The switch works in conjunction with the coolant level switch. If the coolant level of a cold engine is too low, the low level switch will send a signal to the dash after a 20 second post-start up delay to indicate low coolant level. As the engine warms the coolant expands. If the engine is stopped while warm and re-started the low coolant warning will not be triggered. If the low coolant level switch was activated, then on subsequent start the low cooling system pressure switch is activated the central warning system will store this sequence of events and maintain the low coolant warning even after the coolant has expanded due to heat and the low level switch is no longer triggered. In other words when starting the engine again the warning lamp comes on even though coolant level appears correct. If the coolant tank cap is opened (to add coolant for instance) the pressure is released and the pressure switch circuit opens. The Central Warning system interprets this as coolant has been added and turns the warning lamp off. It is intended to save on troubleshooting, but typical to much of the CTO (compulsive Teutonic over-engineering) it is often removed if it fails and not replaced.
