Add it on the low side of the system.This is the line that gets cold and is bigger in diameter than the high side pressure lines.Hope your useing guages,as a safety precaution,if it is a partial charge! Watch the site glass if there is one,on or near the dryer! Charge the system at above idle around 1200 rpm so it will stabilize pressures to acurate read outs.
