Wannajazz I saw this site and the thing I was wondering was it shows 3 wires to solder but I only have 2 wires soldered to my jack, so I guess I have a Mono jack.

Now if I were to get the stereo jack, do I solder the black battery cable to the jack and if so which terminal do I solder it to ? Heres a pic of the jack I think I need to get..
Any advice on this would greatly appreciated as I am not very informed on this things...Thanks Guys
