Edit - here is a good thread on connectors:
2010 Ford Connector catalog is attached.
.
Link to the 2023 Ford Connector catalog:
.
NOTE: For the most part, the connector PART NUMBERS will apply to '03 and '04 model years also. I do not know if the Wiring Manual connector numbers do or not.
The PCM connectors, FICM connectors, and all of the common sensor and actuator connectors will work on ANY model year. I just "hedged" a little with the thread title, expecting to get even more detailed as time goes by.
Connector C1282 provides critical power to the FICM and multiple critical sensors. Shorts in this connector (and the wiring to and from the connectors) have resulted in lack of injectors firing and subsequent no-start, and even a no-start condition from low or loss of PCM Power (short in fuse 22 circuit).
Recognition to @xstroker for giving me the "push" to start this (have been wanting to do it for some time now). I have this in his thread in the ELECTRONICS sub forum, but thought it would be good to post here to get some more views and hopefully get some of the gaps filled in.
