Sylvan Pro Select Wiring

[Doug/SD]

Just got an hour meter (Yamaha) (present from my wife) to install on my ProSelect. The instructions with the meter do not match the wiring color codes under the dash, at least not as far as I can tell. The meter has 4 wires (2 yellow, 2 blue). Has anyone wired up an hour meter to a Pro Select, especially if it was a Yamaha meter. If so how did you do it.

Thanks a lot for any info. Doug/SD
