2014 22SFX Fuel, Tach, & Trim Gauges all DOA at same time.

Checked √:
Grounds √ok
5amp Breaker (under the switch) √ok
Switch √ok
My next thought is the 10amp inline fuse on the common purple wire leading to the engine ignition positive (+) from each gauge.
Where is it located? Under the cowl? In a harness by the engine? Or elsewhere?

(see the attached electric schematic diagram as provided by the good folks at Benny)

My guess would be a main fuse back by the battery or inline from the battery under the helm.

That's my guess as well. The question was for anyone that has actually seen the purple fuse. Where is it?
