The ACS 179A wiring harness should be constructed of Tefzel aircraft wire (M22759/16 grade). Power
and ground wires should be 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. Important please
note the power of the unit before installing; it will be either 14VDC or 28VDC and clearly marked
as such on the units data tag.
Pre-fabricated cable harnesses are available from Air Comm to expedite installation consult our
sales department for details.
