Trying to figure out how to display tach on my GPS, I know there's got toy be a way if the engine is digitizing RPM's for digital Yamaha gauge.
All the 2 stroke 70s are the same from 2000-2008 I believe. I have a 2000 70TLRZ and a 2008 70TLR? and everything is universal. The square connectors that plug into the smart gauges should have an RPM signal wire that can be used. Anything is possible it just depends on how far you want to go.Depending on the year its possible. I know my 2001 will not do it.
