I didn't like the idea of so many extra cable splitters and gender changers (all potential failure points), so I cut and crimped in four additional data wires where the main loom joins the ADAHRS sensors and ran them out to the autopilot servos. Neither the main or redundant power wires & grounds go to the servos from this point. Instead, they get power from the main bus (via a dedicated fuse or circuit breaker). I also ran the yellow wire from the pitch servo to the roll servo and forward to the disconnect switch. Everything seems to work fine.
