The existing autopilot disconnect circuit must be run through an internal relay within the
EA100. This ensures the autopilot cannot be engaged or will disengage if the EA100
attitude is invalid.
The autopilot “sonalert” or disconnect tone must not be interrupted
with this relay. Wire as shown.
20 AWG wire may be spliced to a 22 AWG wire of no more than 4 inches in length at
the EA100 to accommodate the high density pin.
