Keith Browning Posted April 22, 2019 Share Posted April 22, 2019 So I need a PCM relay for this truck - not integral, nothing overly special other than it's a 70A wide blade relay. No listing in the parts catalog. Engineering number does not cross over. Contacted PACO and after a little back and forth they come up with this: "The BJB along with it's respective relays and fuses are not individually available for service. Must order the entire 12A581 harness assembly. KC3Z-12A581-BSA" WHAT? The number on it - JU5T-14B192-FEA - found it on Google but that does me little good. Need to find it or a substitute.

Keith Browning Posted April 23, 2019 Author Share Posted April 23, 2019 For the moment I installed a new FICM power relay F80Z-14N089-AA which meets the specifications of the original relay AND appears to have fixed the truck. PACO is still working on it... Quote Link to comment Share on other sites More sharing options...
mchan68 Posted April 23, 2019 Share Posted April 23, 2019 How ironic. I'm just in the middle of replacing that very harness on a 2018 F-250 6.7L with all of 2000 miles on the clock. 1 Quote Link to comment Share on other sites More sharing options...
jw33 Posted April 24, 2019 Share Posted April 24, 2019 I have one to do on 2018 gas 250 when it comes off of backorder, i have replaced more wiring harness on the new body style than i care to remember, and no one truck is the same problem Quote Link to comment Share on other sites More sharing options...

Keith Browning Posted September 25, 2021 Author Share Posted September 25, 2021 I just love doing those power distribution harnesses. Quote Link to comment Share on other sites More sharing options...
forddieseldoctor Posted September 26, 2021 Share Posted September 26, 2021 Yup. This one was customer pay at least. Guy removed inner fender for some reason or another. And never put it back in. Fuse box took the hit. Quote Link to comment Share on other sites More sharing options...
