Does anyone have a wiring harness diagram
 

1998 F150 4.2L V6

Need a wiring harness diagram, specifically showing the pinouts for the two big connectors on the firewall and PCM.

There used to be a link on this site where you could download the manual. Do a search.

I don't know whether it has wiring diagrams or not.

Thanks, but I have that, and it doesn't contain anything that I can find about harnesses or connectors. In fact, no electrical schematics or wiring diagrams at all that I can see... just an electrical component locator section (which is almost useless).

I finally found some wiring diagrams that show the connections from the PCM to various components (4 pages/parts), but it doesn't show any connectors or say which harnesses contain what.

Thanks. Unfortunately the link to the file doesn't work anymore.

Post #126, this link works.

I just noticed it, this an old post! Please someone delete.

This is from a 99 4.2, no quite sure if its the same as the 98. Hope this helps
