2.3.4 Connector Assembly
The unit connector mates directly with the circuit boards in the PXE7300. The connector (part number
120-425-4402 is a Molex crimp-type, and requires the use of a Molex hand crimp tool, EDP P/N 11-01-
0203, CR6115B (or equiv.). The connector is mounted to the unit tray with 2 ea. #4-40 screws, from the
inside of the tray. Ensure that proper strain relief and chafing precautions are made during wiring and in-
stallation.

2.4 Cable Harness Wiring
Referring to the appropriate Appendix, assemble a wiring harness as required for the installation. All wires
must be MIL-SPEC in accordance with current regulations. Two- and three-conductor shielded wire must
be used where indicated, and be MIL-C-27500 or equivalent specification. Proper stripping, shielding and
soldering technique must be used at all times. It is imperative that correct wire be used.
Refer to FAA Advisory Circular 43.13-1B and 2A for more information. Failure to use correct techniques
may result in improper operation, electrical noise or unit failure. Damage caused by improper installation
will void the PS Engineering warranty. PS Engineering can provide a custom made harness, visit www.ps-
engineering.com for more information.
2.4.1 Noise
Due to the variety and the high power of radio equipment often found in today's general aviation aircraft,
there is a potential for both radiated and conducted noise interference.
