so i started getting a tps fault so i went to investigate and image shown is what i found. i dont know why someone would have done this and not even atleast wrapped the wires back up. Im just curious if anyone has a clue why someone stripped the 4 wires. im suprised i wasn't having issues relating to this before this weekend. well aside from my original post from when i joined up. maybe someone was just trying to diagnose an issue and forgot to tape them up. either way if someone has some geusses of other possibilities. may even lead to other locations i should investigate.

My 2008 ford explorer had same problem triggering false positive engine codes on my FIXD scanner/app that cleared once I insulated each cable with electrical tape. I started having minor irritating electrical issues so I sold it at 197000 mi.

you make jokes but ive seen dumber things done but ive usually found a reason it was done. i wasn't aware there was a poor wiring issue in these trucks. geuss i should be on the lookout for more wiring problems.

Regarding root cause:
- Are there bits and pieces of the wiring inside the convolute? This would indicate brittle insulation that broke with time
- Was the convolute chewed up at all? This would indicate rodent

In my case, the wires were not taped past the convolute. There was a bend immediately after the convolute and the convolute chafed the insulation off. This was true in all 4 cases where I made a repair.

Not that it matters to much what caused it but I would bet my a** that was a rodent of some sort. If you zoom in really close there are tiny bits of the wire insulation looks like it was chewed. I’d be setting me some traps!!! My recommended repair is depinning that plug and sliding shrink wrap on each wire and maybe even one around the bundle. Good luck catching Speedy.

Actually, the best news for you would be that this was done intentionally. This might mean you don't have issues with deteriorating insulation which would be a much bigger headache as time passes.

I learned many years ago to visit the forums covering vehicles I intended to purchase. Then spend a lot of time reading posts. It has saved me from buying into a lot of problems.

Looks like mice have been gnawing on them. I live in the country and that is a common problem. Mice teeth never stop growing, so they gnaw to keep them in check..

I do like the looks of them but they could stand to be refinished. I am on the fence about the low profile tires on an SUV though. The ride quality is not as good as my old 2002 Explorer due to the thinner sidewalls. Also, they aren't what I would want for off roading situations.

replace the motor side harness trust me i have had four of these and this goes for everybody with 2002-2010. Once the harness get brittle it is going to keep breaking in different places even under tape. Save yourself a lot of time and heartache just buy a new one. DO NOT buy a used one because you will have same issue

It’s not mice. It’s not stripped or cut. It’s bad insulation.

You suggested buying a new harness, I’ve been looking for one for an 06 4.6 and every place I looked says they are discontinued. Where did you get your harness?

So, for the 4.0l engines, is this the correct harness that needs to be replaced?: 8L2Z-12A581-BA

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.

I believe that it is most likely to occur in 06 & 07 V6 models. It could be a numbers issue, many more V6s were sold than V8s.

I have seen posts here where it has happened in V8 models too. It would be interesting to know if this occurs in vehicles that are driven in a certain type of climate(s) or if driven a lot on gravel roads with certain underlying soil types etc. These issues seem to happen somewhat frequently but if it was solely caused by insulation material, without other mitigating causes, I think we would see a lot more people reporting this problem.

Thanks to both 94Eddie and Beachcomber86. I think mine has spent most of its life inside rather than sitting out. I will try to look at mine and see what condition the harness is in and report back here. Out of town right now.
