Yamaha Fuel Management Guage

[<TY>]

Need some help please. I have a Yamaha Fuel Management gage that I would like to interface to my GPS. My problem is MY GAGE only has 4 switches not the six like most people. Anyone have the switch setting for a 4 switch set up. Thanks for the help

If you only have four switch's, then that is an older gauge that would only work with Yamaha Speedometer. I beleve it was 1999 or 2000 They changed the fuel management gauge to 6 switch's for the option of Speedo or GPS

I'd appreciate the switch settings, diagrams and details about how to connect GPS to fuel mangement guage.

I got documentation from Hamfisted on forum. According to the docs the newer guage came out in 1998.

I'll be glad to share with you -- email me and give me address to send to.
