The low side service port is located on the receiver-drier or

accumulator cannister that is mounted on the right side (passenger

side), back of the engine compartment and near the fire wall. If

you look behind the battery (firewall, not fender) and under the

block of wires on the the L-shaped metal bracket mounted on the

firewall, that is where you will find it (should have a grey or

black cap). Good Luck!
