Upgrading to four slot. Need good advice.

I know I need to add a select button on the 26th connecter but what kind of pins does a jamma connecter use. What size is it and does Radio Shack have it? Also, I need to upgrtade to stereo but what is the setup? I been to HardMVS and I can't seem to find a step by step instructions. I not a total retard in electronics but I just don't want to mess up my new toy. Besides the work I need to do to my arcade, I love the four slot. Four slot PCB beats a one slot PCB any day!!

PS, talk to Briggs (runs hardmvs.com) and he can hook you up with any wires. dont be afraid to ask him for info aswell. he's super cool.
