Rigging a 2009 90TLR 2 Stroke

[Shrbnd]

I currently have a 91 Yamaha 90hp that I am replacing with a 2009 90hp Yamaha. I'd like where ever possible to use the same parts when rigging the new engine. Are there any new parts that I would have to order because the older parts are incompatable? Wiring harness, digital tach, analog speedo? Any advice would be appreciated?

Thanks,

Paul

Everything will work except the the digital tach, need to replace tach with 6YR-W0035-E2-00 Multifunction Tach kit
