Hi there I fitted the Acumen to my 2005 FZ6 and i'm no electrcian but the info given on the forum was tops. Use a good fine soldering iron and some shrink wrap to fully protect the wires. One problem was cutting into the speedo wire which then makes it short, get some spare fine wires and uses these to join up the wires when you have cut them. Also cut the wires as far away from the contol box connecter this will give you mor flexablity.
Best thing I ever fitted the time I;ve thought I was in 5th and tried to change up.
Best wishes..
