When I pulled my motor awhile back (s14 SR in 97 chassis), I disconnected the 2 hard lines to the A/C compressor instead of just taking the compressor off and leaving it to the side (noob mistake I know).

My question is, now that the car is all back together, can I 'recharge' the system myself? Or is there more to it than I know, and I need to pay somebody at some random place that I don't trust to touch my car?
