I have a 2004 F250 Lariat 6.0 Build date of 5/04 Just reaching 400,000 M. I'm in need of a new wiring harness, tired of just replacing pigtails. Wires are old and brittle. So I can only find two different part numbers to replace this with. One before 9/23/03 part 3C3Z12B637BA and one after 9/23/03 part #4C3Z12B637CA W/O heater. My question here is will part #4C3Z12B637CA W/O heater work on my truck? My truck came with the heated fuel pump which I have replaced along with the upgraded pigtail and now does not have the heater.
Thanks
Thanks
