It should be on the Low pressure line right above/next to the pass side shock tower... But that doesn't sound like your problem...
What do you mean the pressure is "wicked high" ?
If the compressor isn't turning, you should see equal pressure on the high and low sides... I think the last time I checked mine with the AC off, it was reading around 120psi. With the AC on, it would drop to around 35 psi on the low side...
If the compressor won't engage, have your pcm scanned to see if there are any codes thrown.

CheshireCat is correct.
You also have to pull and short across (at least I did) the AC relay in the relay box in the engine bay. That will get the compressor engaged so you can check the pressure and make it accept refrid.
