Default Re: wiring harness failure details (for reference)

By the way, I had to remove the harness 50% before I could move it around enough to see the abrasion point. It’s a very difficult spot to see when everything is together, but wouldn’t be difficult to cut the zip tie. Pics coming eventually... I wrapped the area in extra rubber this time, in hopes for another 200+k miles

Now take note of this:-
That support bracket MB pt# A-901-546-03-43 is now obsolete we used our last one today.

That's the bad news, now the good!

Mopar men in Milwaukee have 89 of them, under part number 5120947AA
I ordered 10 off for stock.
Now you might ask why do I need 10 off.

Well the answer is simple
We see so many discarded when harnesses are worn through & shorted by abrasion on the fuel filter or steering column. This bracket is essential for harness longevity .
Check yours for security and grab one before they are gone.

I understand that your business needs to have the part for future OEM type repairs.

Can't a DIY owner just cut things loose, add some rubber or plastic for abrasion resistance, and re-assemble? Much like I have added DIY mods for quite a few possible harness area problems which I identified and addressed? The harnesses in my 2004 and 2006 have had some pretty obvious problem areas.

Heater or fuel hose slit to fit is often my choice for abrasion resistance. That said, simple vinyl electrical tape will work for the leftover life of a T1N Sprinter.

Well of course.
As a DIY'r and being your own vehicle you are free to do whatever modification is felt necessary.
In a Pro shop however the customer is expecting a full technical repair according to factory specs, which is often the cheapest option to execute .
The bracket is just over $2,00 retail and often found missing.
Replacing the missing bracket and zip tying it up per factory methods is a very cheap remedy to returning the harness anchors and security to a factory spec.

If I have it correct, this is the item:

I am surprised that the bracket is often found missing.

Yes that's the bracket AND I can confirm its often missing when a harness has failed rubbing against the column.

Observing/inspecting the bundle next to the fuel filter has proven inconclusive in my case. Does the bundle typically exhibit obvious abrasion damage?

I have no driveability issues. Just looking to prevent them.
I have an assortment of beer coozies from various events I use to wrap around the harness and the re zip it back to the bracket... I do this on every sprinter I see.

I wonder if it would be a good idea to inject some neutral cure silicone into the harness bundle near this bend? That would prevent the wires from chafing on each other, and wouldn't be impossible to remove down the road if needed.
