The install is very easy, and the component is a must-have:
<The install is a piece of cake. The only thing you need to remove is the seat - no need to mess with the tank or any plastics. While looking in from the right side of the bike, you will see a wire coming from the top of the transmission case, right above where the countershaft resides. Follow it up to a vinyl boot and you will find the connecter. Simply plug the correction unit into these and mount somewhere under the seat. I ended up setting the dip switches for 12%.
There is room in the right front portion of the storage compartment to mount the unit. I used velcro for attachment and dremeled out a bit of plastic so the wires would not get pinched.>
I have since reset mine for 11.5% on the 954 as I think 12% was a bit high, but still have not checked it again with GPS to confirm this. This will definitely get you in the ball park though.
