The low side.
AC recharge port. is arms length down the left front of car on top of evaporaterator has a blue cap. Is very hard to reach your arm between the radiator and the motor to reach this port. You should get an extention for the recharge hose. I burnt my arm because you have to have the car running to actually put the 134a in.
Civic 91 LX still dont have Obd Port on it. Obd is Usually use for a car with ECU (electronic control unit).
Probably an electrical outlet near the door of their house closest to driveway or car port.
Not a DIY job. Take it to an A/C shop. Actually, isn't the ac right in the front of the engine. It looks like a large cylinder, and it's a little longer than the alternator. It's right on the front left of the engine connected to the belt assembly. All you have to do is pick up a recharge unit at an autoparts store and use the low pressure port (the one on the far right of the ac unit) to fill it up. Usually you have to have the car running with the ac set to max to do the recharge though.
Look under car...look for blue c as p near compressor...
it usually has a blue cap on the suction port.
Black capped port on the front left (as you face the car with the hood up) of the engine compartment. It's right by the radiator in my 3.4L SE1.
You don't need acid to recharge the car battery. You may need to top it with distilled water and put the battery on the charger. You may be able to get the acid from a car battery shop, but some of the new car batteries now come as a sealed unit.

On the side of the receiver dryer. You can find a diagram of this on the below link. Just follow the "Find your low side Port" icon.
