Could someone please tell me where to find the high pressure connection for
the AC on the 850 Turbo? Found the low pressure on the LHS with no problem
but couldn't find the high anywhere.

It's probably right in front of me but I couldn't find it anywhere.

TIA

There isn't one. There is a pressure sensor that feeds pressure info to
the fuel computer (yes fuel computer) which is in charge of making the
final decision on whether the compressor is going to be switched on or
not. At the same time this pressure signal is also used to control the
rad fan. So if you have a fancy Volvo system tool you can read the
pressure that way, otherwise you're out of luck.

P.S. That pressure sensor is right beside the low pressure connection.
