Yamaha Fuel Management System

[high desert]

I am considering installing the Yamaha fuel management system on my boat. I have a 2006 Yamaha 90 and T8 so I think I need the dual motor system. Has anyone installed this system and had a good experience with it in a similar situation? Is it easy to install? Does the wiring harness just plug into existing plugs on the motors? Any advice would be greatly appreciated.

Thanks
