Moding a Neo Geo CD to Regionless.

I just won a auction for a Neo Geo CD. I have very limited skills when it comes to soldering. Seems easy to mod the Neo Geo CD. I bought mine from a US dealer, but there's a possibility that it's a Japanese one. If it's a US one it's easy clip a jumper solder a wire to each stub of the jumper wire them to a switch. If it's Japanese it doesn't have a jumper and I'll have to solder to the board to the switch. It's probably going to take a week or so for me to get it. I have quite a few projects ahead of it. Also want to practice a bit. Hopefully I'll get to it in a few weeks or a month. 

Anybody done this? Or similar projects? Have any pointers?
