neat seeing the variations on each of the different models!
If you look in the factory service manual and the factory parts drawings, they show for 85.5 up as low side by the fender, and high side by the dryer. However, there is a notation in the FSM that the configuration is changed for 87-up, to high side by the fender, low side on the compressor. The low pressure switch is in basically the same location on both.

Some of you may remember me posting a while back that I couldn't get my A/C to charge correctly. Among other problems, I wasn't looking at the lines, rather I was taking the drawings for gospel. Skinny lines are high side, fat lines are low side. I had been trying to charge my car through the high side. Doh!
