6.0 MAIN wiring harness
 

Can any of you seasoned pro's tell me the FORD part # for my 2003 6.0 ?

If not pushing favors to far...... the original part # and the latest revision would be nice.

FORD had their way with me since I ordered the 2003 new and keep putting it to me on parts pricing every since. I think I have paid for the thing twice by now. Original sticker price and then each and every part seperately.

FORD Part # 3C3Z-12A581-MA
 

In case anybody else ever search for this it (depends on your VIN #).

My 2003 'early build' F-250 6.0 was FORD Part # 3C3Z-12A581-MA

Not sure what a 12A581 is....basic does not look familiar off the top of my head. I THINK it is the FICM/Inj harness.

The main engine harness is 12B637 -- if you give me your VIN, I will get you the part number you need.

Need help finding part # for early 2003 6.0 engine harness. Was going to order the one you mentioned in this thread but you mentioned if you had a vin you could get the correct one for that vehicle. My VIN # 1FTWW33P43EC94836. I'm finding wires that I touch the insulation is just falling off. several shorts causing no crank. Need help.
