The existing autopilot disconnect circuit from the KA136 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. Wire as shown.
Only KCP299 flight computers with adapter board 065-5016-XX may
use this drawing. Flight computers with 065-5015-XX adapter boards
not approved.
18 AWG wire may be spliced to a 22 AWG wire of no more than 4
