Connection example:

CIC Temperature Sensor, P/N 05257 (2 wire). Connect positive lead to both J1-25 and J1-63. Connect negative lead to both J1-44 and J1- 53 (Chassis Ground).

Other probes may have three contacts.

Substitute Ground Speed for Airspeed (airspeed is not available with this air data input)
