Where is the low pressure side port for A/C?
Where is the low pressure side port?
I found a black cap on an A/C line on the passenger side and toward the front of the engine (is this the correct place)?
There also appears to be a port on the tin can looking thing up by the firewall.
I seen the diagram and it doesnt seem to make sense. Can anyone post a real picture?
Any help would be appreciated.

That is the low side port. The other one is the high side port which, should you manage to get it connected, can turn that can into your own personal IED when the compressor engages.

I would recommend that you not try to recharge your A/C with a simple can tapper. Go get yourself a proper set of manifold gauges and do it that way. There are 2 ways to add refrigerant - through the low side port with the can upright (feeding gas) and the engine/compressor running, or through the high side port with the engine OFF and the can upside down (feeding liquid).

Doing as you suggested will result in only a partial charge and must be done into a vacuum. You still can't do this sucessfully and properly without the aforementioned requirements.
My advice: Don't give this out as advice to neophytes.

If you haven't already found it, it is near the top of the condenser on the passenger side rear of the engine compartment - or about 8 inches directly behind the yellow head of the tranny fluid dipstick. It is difficult to see because there is a black cap on it and everything around it is black too. I just used the same regular R134 adapter I use for everything else with no problem.
