The ACS 300A wiring harness should be constructed of Tefzel aircraft wire (M22759/16 grade). Power
and ground wires should be 18 or 20 AWG, and all other wires may be 22 AWG. Shielded wires should
be used where noted. Adequate protection against wear and chafing should be taken by using a braided
cable sleeving or jacket. Before completing installation, verify that all cable connector pins are seated
properly and that the connector is securely mounted to the unit mating connector.
Pre-fabricated cable harnesses are available from Air Comm to expedite installation — consult our sales
department for details.
NOTE: Pins noted NC = No Connection.
