Thanks for coming in. I am not sure how to describe what I need. Its the passenger side wiring harness ( comes out of the PCM? ) that connects to the O2 sensors and the transmission. I am sure it runs other stuff but those are the items I am pretty sure it controls. The main part that I am concerned about is the transmission connection to the PCM. I have searched all over and am unable to find the harness. Any help or a point in the right direction would be great. Its a 1999 F250 4x4 single cab automatic 5.4L 256K miles 4l60?

Thanks - Chris

 

The harness should have an ID tag on it to refer to for the part number.
These may not be available from the factory any longer.
Used from a yard or luck finding one is the only way.
The harness communicates with the transmission, all 4 Ox sensors, the EVAP system.

Good luck.

 

CRAP, what are my options other than the junk yard? I am sure it will be messed up as well. seams like some one should still be making them. i dont even know whats its called. what do you think its called?
Thanks
