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 manhours into this diagram. Please be patient while it downloads. If you're on a dialup 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 rightclick on the thumbnails below and choose "Save Link As...". The diagram legend is also displayed below for help in deciphering the diagram contents. 1972 Ford F100 thru F350 Master Wiring Diagram Image Size: 11,438p x 1698p ~ File Size: 1.72MB Page 1 Sec. 110 Page 2 Sec. 1120 Page 3 Sec. 2130 Page 4 Sec. 3140 Page 5 Sec. 4151 Page 6 Sec. 5260 Page 7 Sec. 6175 4187p x 1536p ~ 1.01MB 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 pinout. NOTE: This legend is accurately replicated from the original OEM factory wiring diagrams, including three connectors (C24, C38, C80) which have the same connector ID number but multiple differing pinout 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 pinouts 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).
