1. Coverage
A. The Wiring Diagram Manuai is prepared in accordance with Air Transport Association Specification
100 for Manufacturer's Technical Data.
B. The information in this publication is based on data available at the time of publication and is
updated, supplemented, and automatically amended by all information issued in Service News
Letters, Service Bulletins, Special Service Projects, Supplier Service Notices, Publication Changes,
Revisions, Reissues and Temporary Revisions. All such amendments become part of and are
specifically incorporated within this publication. Users are urged to keep abreast of the latest
amendments to this publication through information available at Cessna Authorized Service Stations
or through the Cessna Product Support subscription services. Cessna Service Stations have
supplier publications which provide disassembly, overhaul, and parts breakdowns for some of
the various supplier equipment items. Suppliers publications are updated, supplemented, and

WARNING: ALL INSPECTION INTERVALS, REPLACEMENT TIME LIMITS,
OVERHAUL TIME LIMITS, THE METHOD OF INSPECTION, LIFE
LIMITS, CYCLE LIMITS, ETC., RECOMMENDED BY CESSNA ARE
SOLELY BASED ON THE USE OF NEW, REMANUFACTURED,
OR OVERHAULED CESSNA APPROVED PARTS. IF PARTS
ARE DESIGNED, MANUFACTURED, REMANUFACTURED,
OVERHAULED, AND/OR APPROVED BY ENTITIES OTHER THAN

7. ManuallUsage
A. Purpose.
(1) This Wiring Diagram Manual has been prepared by Cessna Aircraft Company to assist
customer personnel in locating, tracing and repairing of aircraft wiring and components. The
wiring diagram manual may also be used to assist in ordering replaceable wiring components
and in identifying new and reclaimed parts. It is not approved for any other purpose.
B. Effectivity.
(1) Due to limited space on the parts list, the effectivity is listed under the title and includes the model
number. Effectivity within the top effectivity is listed in a parts column and does not include the
model number of a serial.
EXAMPLE: 80001 - 80004 would Indicate the part listed Is applicable to serial numbers 18280001
thru 18280004. 8001 - 8004 would indicate the part listed Is applicable to serial numbers
T18208001 - T118208004.
.1
(2) Airplane effectivity is indicated in the parts list by a ten-character alphanumeric code. The
first five characters indicate the first applicability and the last five characters indicate the last
applicability on an unbroken sequence of assigned airplanes. When an item is applicable to all
airplanes, the column shall be left blank.
(3) Avionic configurations are standard avionics package, NAV I option, NAV 1I option, or NAV Ill.
Sections of this wiring diagram manual that are unique to a specific avionics configuration are
listed as STANDARD, NAV I, NAV II, or NAV Ill.
C. Identification Procedures.
(1) Wiring Diagram Manual Numbering.
(a) Numbering of chapters, sections and subjects within the Wiring Diagram Manual is in
accordance with ATA Specification 100. This same numbering system is utilized in the
Illustrated Parts Catalog and Maintenance Manual to allow for easy cross- referencing
between the three books. Refer to Figure 1 for an example of the numbering system.

(2) Wiring Diagram Page Numbering.
(a) Page numbers 0 thru 100 are used to number wiring diagrams. Sheet numbers are used
for diagrams that require more than one page for illustration.
NOTE: Whenever a diagram is referenced to another, only the diagram number is
used. Therefore, where there is more than one page of the same diagram, it
is necessary to refer to the effectivity block at the top of the parts list to make
certain the diagram applies to the airplane of interest.

0. Wire Identification and Numbering.
(1) In each electrical and electronic wiring circuit, the wires are identified by a number-letter code.
The code is either printed, stenciled or banded on each wire segment. A wire segment is a run
of wire between two points in a circuit. The number-letter code explains where the wire is used.
Refer to Figure 2 for the wire identification system.

E. Parts List.
(1) Electrical and electronic equipment used in the wiring diagrams are identified by an alphanumeric
reference designator. This reference designator is used as a cross-reference to the parts list
where the part number and part description are shown. The five digit Federal Supply Code may
be found in the Suppliers Address List to find the suppliers name and address.
(2) Most reference designators consists of two (2) alphabetical characters followed by three (3)
numeric characters.
