Autopilot upgrade

[Learjetter]

Question for the gurus:
My 337G model has a 400A (Af530) installed. Has anyone installed the 400B (AF550), say as removed from a Cessna 210, in a 337?

I’ve got 400A manual, would anyone have a 400B manual available so my shop technicians can compare the wiring diagrams, part numbers for servos, etc for compatibility?

Look in the AFM Equipment list and see if the "B" was offered. Another source would be Autopilots Central just NE of you. The boss man told me that the B would outfly the STEC 55 as it uses torque motors for control input, very smooth.

My equipment list shows all manner of 400 options, but no 400B. Back to the idea of getting DER approval to interface Garmin to 400A.
