Magic 3.5 Install

Hello everyone. I'm kinda new so please be easy with me. I have purchased a Magic 3.5 chip and had my buddy do the installation but we have come across a wall. It seems that based from an online diagram, a wire/point "S" is to be soldered between two points. Now, my friend isn't exactly sure if this is the case, or if it's possible that the arrow pointing from the diagram was not clear. Can anyone who has installed this chip give us any ideas on where to go and what to do? My bud took a chance and soldered it on the "left" point but he's unable to load backups...only original games work. Sorry if i'm not making sense to some of you. For clarity, I have pasted the link. I would very much appreciate a response from anyone who has input. Thanks!
