The installer will provide all wiring and cabling unless otherwise noted. Use MIL-W-22759/16 (or other
approved wire) AWG #22 or larger wire for all connections unless otherwise specified. The supplied
standard pin contacts are compatible with up to AWG #22 wire. RG400 or RG142 coaxial cable with 50 
nominal impedance and meeting applicable aviation regulations should be used for the installation.
