Help me before I have to join a ricer forum! :(

My beater is a 1984 Toyota Crapolla SR5. I got an A/C conversion/recharge kit but can't figure out which fitting is the low-side. Unlike other cars, this one has 3 fittings and they all are the size of the low-side fitting supplied with the kit. There are supposed to be only 2 and the instructions say "You can't get it wrong, it'll only fit on the right valve... blah blah"

Anyhow the 3 are:

one on the compressor directly under the alternator
one on a medium sized line running Right-Left in front of the radiator
one on the passenger's side on a thin aluminum line that runs Front-Rear into the firewall

I don't want to die. Help.

The low side is the line coming from the evaporator(inside car) to the compressor, actually it starts at the expansion valve which is incorporated into some vehicles receiver/dryer. I would say #3 is your low side.
