You will have to splice the serial data wire, but that's about it. Here's a schematic in case you need it. The schematic is two pages, even though it looks like one, so that's why it looks funny. I cant put them all on one page and still be able to read them.

Rob, you're killing me, man!! I assumed you had that hooked up all along..... Well, we all know what they say when you assume something.....
