Does anybody have access to a 2013 TXT Pro 300 wiring diagram? Easiest place to pick up power to run electronic clocks from?

Not seen a diagram for the 2013 model but I no doubt suspect you will have ha cable coming up from the flywheel case via a ac/dc rectifier which goes to a 12 volt regulator. This will go on to supply the cooling fan and you can tap into this if there isn't all ready a spare terminal (that would normally be used for lights and instrument panel.

Won't be too hard to find with a volt meter.
