most are on the drivers side below between the engine and the inner fender..

schraeder valve... maybe your blue cap is missing to help identify it.

My 97 has the low pressure port near the left side strut tower in the big AC hose. The high pressure side is on the left side of the condenser and is facing forward. I don't know if RHD cars are reversed left to right.

Another way is to find the big hose on the compressor ( suction ) and follow it towards the cabin / firewall / the low pressure port will be somewhere along there in a reasonably easy place to access. High pressure port will be in the smaller hose running from the condenser to the cabin / firewall.
