I got a PM request for some electrical information on the 2002 7.3L. I am going to post up here what I have for the requester and anyone else who is so inclined.

There are 10 or so files. I will attach them over this post and the next. Anyone having a need to respond should wait a few minutes for everything to go up.

The following conditions apply:
  • The files may have already been posted. They are simply files that I have encountered along the way.
  • The files may be redundant to each other.
  • The files may not be completely accurate. I do not have a 7.3. I have nothing with which to check them against.
  • Someone may own these files. If so, they still do. Be sure to send them a thank you note.
  • Someone may have converted this data to electronic. If that is you, take a bow.
The person asking was @GETFURIOUS . Here ya go...

Some were duplicates, so 6 files total. Here are the rest.

@djmaguire
Any chance you would have the same for a 2001, kind sir?

I will respond to the above and your PMs here because the answers are probably of interest to others.

No, I don't have a specific 2001 wiring diagrams. The electrical information online for the 7.3s appears to have occured in two waves - 1997 and 2002. There is some 1999 info, also. ...but not specifically wiring schematics.
From what I have read, most people use the 1999 info for the 2001. Not the best, perhaps, but better than nothing.

I saw that you saw the 1999 Workshop Manual that I posted online here (link for others):

https://www.powerstroke.org/forum/99-03-7-3l-general-discussion/1349899-7-3l-1999-workshop-manual.html

...so that might help. There is also a good simple diagram in the 1998-1999.5 7.3 coffee table book. You can get that here:

Coffee Table Books - Diesel Technician Society

...and there is the 1998-1999 PCED that might be useful:

https://www.powerstroke.org/forum/94-98-7-3l-general-powerstroke-discussion/1286306-ford-7-3l-diesel-powertrain-control-emissions-diagnostic-service-manual-1998-99-a.html

There is also some early 7.3 electrical stuff there, although the PCED is - I believe - for the 99+ version 7.3s.

A 2001, from the standpoint of a schematic, is treated as Either a 2000 if it did Not get the mid-tern electrical upgrade, OR a 2002 if it Did.

You can tell which one applies to your truck by simply looking at the Instrument Cluster. The upgraded 2001's have the same cluster as all the '02's & '03's have. It has a Digital Odometer and a Trans Temp Gauge in it...

Cool and thank you for the information. I did not know or realize that difference. That must be one of the differences of that late March build date I keep seeing referenced. I think it's March 26th, 2001. I.e. Lower Radiator Hose ; Before = xxx#; After =yyy#.
Mine has a build date of early March, analog odometer, and no transmission temperature gauge (that I would like) sooo...I guess it's the same as a 2000 then. Thank you for that, sir. You have imparted knowledge to me and for that I am grateful. :thumb:
