Start by selecting the model year of your coach from the
left frame. Note that only 1997 model year and newer are
available online.
The list of available models is divided up by
families. Select your model.
The wiring information is broken down by 110 volt, 12 volt,
and function. We have both diagrams that show the logic
and installation drawings that illustrate routing of wires and
the location of electrical components.
Acrobat Reader is used to display the Wiring Information. Helpful functions are noted below. For additional information, see the Acrobat Reader on-line Help.

The Wiring
Identification Guide
provides the codes
printed on each wire.
Using this code, you can
determine purpose and
to from location of the
wire.
Lower right corner of the drawing will contain a title block. Depending on what sheet and/or frame of the drawing you are viewing, the title block will be in a different
format. The important elements of the title block are noted below.

To navigate a drawing, it is broken down into zones or areas. The drawing border contains the zone locationsalpha locations on the side borders and numeric locations
on the top & bottom borders. You locate an object in a drawing similarly to locating a city on a road map. By using the zone locaters in the drawing border, you can
locate objects on a drawing.

For example:
To locate the housing at zone D-3, first locate zone D in the right or left side drawing border, then locate zone 3 in the top or bottom drawing border. The area on the
drawing where those two meet is referenced as zone D-3. Sheet 1 Frame 3

A multi-frame drawing is a long drawing that is split into sections or frames. Frame counting begins on the right and goes left.

A drawing that does not contain frames is surrounded on all four sides by a border. A multi-frame drawing will not have a border on the right and/or left sides.

The following example shows sheet 1 of part number 158392 that is split into 3 frames. Frame 1 has a drawing border only on the right edge but not the left edge;
Frame 2 does not have a border on either the left or right edge; and Frame 3 has a border only on the left edge. Option codes are located at zone A-1 and list the optional feature code and a
description of the optional feature. Option codes are noted in the drawing with
an oval.
Delta notes specify important information and are located in the lower left
corner of the drawing. (Note on a multi-frame drawing, the delta notes are
located on the last frame.) The delta note is referenced in the drawing by the
delta symbol and the note number.
Option codes located
directly above the
title block signify
that the entire
drawing pertains to
that option.

Option codes
located on the
drawing signify
that that note or
view pertain to
the option.
A detail view is an enlarged area of part of the drawing. Detail views are defined one of two ways. First by dashed lines and arrows around the area to be enlarged. A
detail identifier is noted between the arrows. Secondly, just a callout specifying the detail. Locate the detail view on the drawing. Note that the detail view may be
located on another sheet of the drawing.

Detail AANote that the detail view is on the same page as the callout. Winnebago Industries built motorhomes have been using two-color wiring on 12-volt wiring since the early 1990s. The wiring is identified first by color, and then with a
combination of numeric and alpha characters stamped or printed directly on the wire. Beginning in 1999, the revision level of the assembly is also stamped on the wire. This
wiring identification is printed on each wire every inch making it convenient to find in close quarters.
This photo shows a yellow and a white wire. Note the eight-digit part number (146740-01) the
revision level (A) and the three-character alpha designation (JJT) on the yellow wire.

The eight-digit part number and the revision level specify the wiring assembly to which the JJT
wire belongs and the alpha characters are used to identify the purpose or function of the wire.
The Winnebago Wiring Identification Guide must be referenced to determine the purpose or function of
the JJT wire. Locate the JJT code in the Wiring Identification Guide (use the Find function of Acrobat
Reader to easily locate JJT).

This describes a 14 gauge yellow wire that connects to a 15 amp power source from the coach battery
(versus the chassis battery).

14 WHT (REF JJT) Beginning with the 2007 models, 120-volt romex in the motor home is now identifiable with a combination of color and text. Each wire gauge is identifiable by the color of
the PVC insulation jacket and, similar to the 12-volt wiring, the text printed on the wire insulation jacket identifies the intended purpose or specific function of the wire. The
PVC jacket on the romex is stamped with information including the gauge of wire, the voltage limitations, and "identifiers" that dictate the usage or limitations for the romex
(i.e., interior applications versus an in-conduit, temperature restrictions / ratings on the wire insulation, etc.).

The photo shows several examples of romex with different information printed on each. This information is printed every 3 inches for easy identification and tracing.
