A/C low pressure port

[Familybird]

Hey all, I need to add coolant to my A\C and I need to find the low-pressure port. Is it the one on the canister or the one right next to the radiator? It is suppose to be on the larger hose running from the evaporator to the compressor, but I don't see this. Car is a "98 Formula.
Thanks, Mark

Don't think those recharge kits will let you connect to the high pressure side for safety reasons. My guess is the low side is the one on the canister, the high side would be the one closest to the radiator (consenser). Beware, even the "low" side is under a lot of pressure.

its dummy proof...it wont let you connect it to the high side since its the bigger one (not calling you dumb)
