I’m guessing they are all prone to it, and areas with high temperature, or temperature swing are more likely to develop issues.
I have an 06 4.6 and the only thing I have seen so far is the two wire plug for the alternator had that problem. Battery light would come on every once in a while. When I pulled it off I found the insulation getting brittle and fixed it.Greetings. Sorry to jump in here, but does this deteriorating wiring harness issue apply to the 4.6L V8 engine as well or is this an issue specifically for the 4.0L V6? Thanks much.
Sounds like an internal transmission issue.Hey MasterTech808, could that be my very intermittent Transmission issue?
when cold if I drive about 1 mile and stop at a light, the tranny will go into N or seem to. Sometimes I can give it gas and it will slam into D but most times have to go to N and back to D for it to go into gear. I was leaning to valve body but after reading your comment, I'm wondering...
1) V6 or V8? 2) Do you have reverse? 3) Getting the wrench light?Hey MasterTech808, could that be my very intermittent Transmission issue?

Distributor? A failing transmission will often set the warning light.1) V6 or V8? 2) Do you have reverse? 3) Getting the wrench light?
- If 1 is V6 and 2 is no, then you probably have a failing tranny.
- If 1 is V6 and 2 is yes and 3 is yes, then it would be worth investigating.
Primary places to check: TPS, MAF, Distributor, Fan. Just look at the wiring from the plug to the harness shield and see if the insulation is missing.
BumpSo, for the 4.0l engines, is this the correct harness that needs to be replaced?: 8L2Z-12A581-BA
My 06 Premier 4.0 Was sold and stayed in Dallas Tx until the day i bought it and it has this issue if that helps. I caught most of it when i did the timing chains so i have not had a issue from it. Truck has 190 some odd thousand on it.Greetings.

That looks like the main harness with the computer connecters on it. All i did to mine was remove the covering until i got to good wire the chopped the end off covered in heat shrink added new pig tails the ones i could find soldered heat shrunk those then wrapped in tape. Easier than a whole harness. Cheaper to it seems.Bump
I have to side with this because I have one in my drive way that was bone stock untouched one owner and saw this in multiple spots. Even a pic of it in profile or pictures wherever. Wonder if there was ever a recall we could dig up some place on the web!?!Can’t believe it’s still being debated. It’s bad factory wiring. Period. No mice. No stripping. No previous owners work.
It’s not a recall.I have to side with this because I have one in my drive way that was bone stock untouched one owner and saw this in multiple spots. Even a pic of it in profile or pictures wherever. Wonder if there was ever a recall we could dig up some place on the web!?!
Not even a service bulletin. I called Ford!I have to side with this because I have one in my drive way that was bone stock untouched one owner and saw this in multiple spots. Even a pic of it in profile or pictures wherever. Wonder if there was ever a recall we could dig up some place on the web!?!
