I am almost done with my Conversion. I am putting a 5.9 CR into my 2003 F-250 Super Duty. I am having trouble locating a wiring harness that goes from the ECM to the Firewall. I need one from a 2003-early 2004 with automatic. If anyone knows where I can get one please let me know. This is one of the last puzzle pieces that I need.

Thanks
Dan
