Some lower panel wiring and ECU
Not many progress photos of this stuff because it's pretty repetitive (and a little iterative... few changes along the way)

Fuel shut off valve, will extend lever to it's obstructing the footwell a bit when in off position

switches and breakers wired, low voltage supply for the switch LED's, pwm on the gnd will be provided by the Dynon to dim.

ECU nestled up in under the tank and internal harness running up to panel area. External harness will exit through firewall hole on far pilot side
