It's pretty simple aside from extending the wire for the speedo pick-up. People have complained of the tach not being accurate but I've heard it can be fixed with some resistors. I made a custom mounting bracket because one is not supplied. I don't have the model number on hand but the guys at trail tech are pretty helpful so give them a call and they'll set you up with the right one. I love this gadget, it has lots of cool features and the back light is super bright.
I did have some problems with accuracy, so it went back onto my raptor 660
