Default 1996-up AC questions

Ok, I have these questions that I hope someone with an FSM can answer:

1) Can anyone get me the nominal operation values for the A/C pressure sensor on anything 1996-up?

2) Location of this sensor.

3) It appears that the coolant fan switch has been deleted in later models...so can anyone confirm that 1997 models do or do not have these?

From my 2000 FSM

Here are #1 and 2 for you. I didn't see anything in the index about a switch, but I don't have a way to confirm.

Good....I can swipe a sensor at a junkyard with little trouble. That sensor replaces the coolant fan switch as far as location is concerned.

Now then, another question...and I should have asked this on the first post...does the accumulator on newer models have a switch on them?

I am asking these questions because I am trying to adapt the older HR6 AC system, electrically, to the OBD2 PCM. I THINK it'* possible,
