Answers :

Closer to firewall is where your low side port should be. Your R134 filling hose quick connect adapter will ONLY fit on the proper "low side" connector port at that location because it is a different size than the high pressure port. You can't put it on the wrong port and get it to fit.
The low side should be filled and is always the bigger of the two lines on the system. if the system is too low the clutch won,t kick on so unplug the pressure switch close to an alluminum canister and jump that with a paper clip that should get the pump going. hope this helps!!
