Code 34 error and center muffler whole question? - Land Rovers Only

I have a 1995 Discovery 3.9L. Recently I had my injectors cleaned at Wal-Mart (its something new down here in TN they have recently started, not sure about the whole process, but they hooked up an aerosol can to the hood and had like a pressure guage, from what I could see) Well about 20 miles later I got the "Check Engine Light" and a code 34. I have had the Disco since December '05 and it has had a whole in the center muffler, also there is no rear muffler like I have seen on some websites. So I have just a few questions. I know that a code 34 is an injector error in Bank A. Which is Bank A? Right or Left side of engine, if I was sitting in the vehicle? Also I have read to reset the computer error I have to disconnect the serial link mating plug, but where in the hell do I find that? I have looked all over the net and can't find the location. Also will the whole in the muffler affect performance in any way or is it just louder than usual and unpleasant smelling when sitting still with windows down? Thanks for yall's help

Oh, also it had 145k miles, no other problems really, had a loose starter or alternator wire which i secured, i think it was causing the tachometer to jump around a lil a few days ago. it was the nice clean aluminum looking generator forward of the engine to the right (if you were sitting in the disco). It fixed the tachometer jumping and the battery light. thanks again.
