2002 7.3 harness

I'm looking for the wire that goes from the 42 pin back to the cab of the truck. I've not had any luck locating one. Any help is greatly appreciated...

What udsuth78 said... We are wanting to help, but need a bit more information than 42 pin to back of the cab.

Check out this thread by RigCity recently, it may help you out until we get more details as to what you are specifically looking for.

Also, below is a print out of the 42 pin circuits.

Thanks for replying. I should have been more specific. I need the complete harness from the 42 pin back to the cab,( maybe even through the firewall). It connects to the battery, etc... not the one that connects fron the 42 pin to the entire top of motor and to the other battery.. thanks again.

No worries, we often leave out details when describing something because our mind is familiar with the history of events.

Back to your request for help. Do the diagrams and charts listed above and in the thread linked help you?

The 42 pin connector runs from various components like the PCM and IDM to the injectors and engine mounted relays. Since you now know the color code and the circuit location start/end, I hope this will help.

If not, let us know and we will go from there.
