A/C vacuum 
Where do I hook this thing up at on the car? Do I hook it up where I put refridgerant into the system? The instructions aren't very clear on HOW to acutally use it, just kinda says what it does.
I've searched here and camaroz28.com and came up short.
the car is a 94 trans-am if it matters...
thanks guys, this florida heat is killing me

I have one of these pumps. You need a r134a hose without a check valve in it, that screws on the front of the pump, so when you hook the r134a hose up to it and hook the air compressor to it and make sure you have suction on the end of the hose. Then you hook the hose up to the low pressure port of the a/c, the same one you put the refrigerant in. You need to leave the vacuum pump hooked up for at least 1 hour.
