CABLE HARNESS
Construct the cable harness following the instructions outlined below and per Figure 3.1.
Refer to Section 2: Pre-Installation Considerations, for routing precautions.
Wire Gauge Selection
Use of PTFE, ETFE, TFE, Teflon or Tefzel insulated wire is recommended for aircraft use.
The wire harness should utilize 20-24 AWG stranded wire. Refer to table 3.1 below.

Note: Pins should be crimped using Molex Hand Crimp Tool 63819-0000 (Preferred),
63811-2800 (obsolete) or 11-01-0200 (obsolete). See the Molex Hand Crimp Tool User
Manual for crimp procedures.
Pin Assignment Information
INPUT POWER:
Pin A (keyed) – Positive DC input +10 to 32 VDC power
Pin B – Negative DC input / ground
Harness Verification
Failure to install aircraft power and ground wires in the
proper mating connector locations will permanently damage
the unit.
Once the cable harness is prepared, prior to connecting the
TA102, activate the aircraft power bus and use a multimeter
to verify that aircraft power and ground is supplied with
appropriate voltage on the proper pins within the mating
harness.
