NOTE - PLEASE READ!
The following wiring diagram is an EXTREMELY
LARGE file! It consists of the contents of EIGHT pages
that have been stitched together into a single file. In
fact, I have personally invested more than 100 man-hours
into this diagram. Please
be patient while it downloads. If you're on a dial-up
account, I feel sorry for ya!
Because of the physical dimensions of this file, some older
computers with limited resources might be unable to properly
display it. Therefore, this file has also been broken down
into seven smaller files which can be viewed and/or downloaded below.
To save to your computer for future use, just right-click on
the thumbnails below and choose "Save Link As...".
The diagram legend is also displayed below for help in
deciphering the diagram contents. |

Connector Legend
Every harness connection in the above main wiring
diagrams is labeled with a connector ID number.
Refer to the legend at left for correct connector
pin-out. |
|
NOTE: This legend is accurately replicated
from the original OEM factory wiring diagrams,
including three connectors (C-24, C-38, C-80) which
have the same connector ID number but multiple
differing
pin-out variations. Therefore, be sure the diagram
you’re referring to on this legend coincides with
the connector’s physical location in the wiring
harness. The connectors with identical ID numbers
but different pin-outs are labeled to show their
location on the Master Wiring Diagram. |

Everything shown below this point will help you locate
and identify the various components, connectors, splices
and grounds shown in the above diagram(s). All
links will open in a new window, to allow this page to
remain open for reference.
