The easist way to tell is: The freon goes in on the low side, the high side is used for press monitoring. Thelow side is on a large line,or on the accumulator. The high side is on a small line,or closer to the front of the car

1991 was factory equipped with R12, which is VERY expensive, if you can find it.

If you haven'et, convert to 134a.
