I've just had a quick gander and
this is one I've found. Sorry it doesn't contain any pictures, I do better with pictures than just text haha, that's just me personally though!
Would be nice to have a proper
guide up and running with pictures though as I'd like a splitter myself on mine at some point!
Be sure to check the whole thread not just that part though, someone posted a link to a
guide but the link isn't working for me so must have been taken down?
Hope it helps you figure out
how to do it mate!
