How many times can wires flex?

[CheemsK1500]

IDK, but if it's a Ford Taurus door or the rear hatch on an explorer I'd say about twice.

A LOT of vehicles have wires that either flex at the back hatch or in the door. And I've had to troubleshoot and repair those wires plenty of times on various cars and trucks. I would say that they are just regular standard wires, but I think you are better off with the thinnest wire that will do the job. If you take a piece of 12 gauge, and piece of 20 gauge the 20 will be much more flexible, flex tighter and easier.

I'm sure what you have done will be just fine.

The back doors on Dodge Ram Quad cabs and Mega cab trucks like to eat wires too. I once tore down a back door on a 2007 Ram 3500, and tested a bunch of electrical parts, only to find out that wires had broken inside of the boot coming from the cab. Finding out I tore down that door for nothing was infuriating.

Not very many if it's a 2004 Ford Explorer. LOL It was one of the first things to go wrong and need correcting, the good news was it was so pervalant that there were plenty of videos showing where the problem is and how to fix it, and how miserable it is to try to work with both hands in the door jam.

In our old 2007 Mega Cab, the wires going to the back doors were able to flex about 892 trips to school, 137 drop offs at baby sitter (and pick ups), 212 soccer games, 88 peewee football games, 127 youth hockey games, 8 vacations, 225 trips to the grocery store and 419 other miscellaneous door openings and closings.
The 893rd trip to school killed the speaker and the power lock in that door!
Lol

Your answer was a little more detailed than mine. But I think a similar thought process.

You're lucky with that kind use.

So basically, let it droop a bit so there will be some flex. That way there's not actually a whole lot of wire movement.

And use quality wire.

Yep! My truck is a 06, obviously they didn’t fix the wire issue!

I fixed my door with a harness from a similar truck. The harness new wasn’t all that expensive if I remember, problem was it was backordered. Apparently lots of other people had the same concern

Before I bought my square, I had my dad's old '54 AD that needed rewiring. I reached out to my friend who works at the GM proving grounds. He said the thing to use is GXL or TXL. Apparently the difference between the two is insulation wall thickness. For something with a lot of bending I might go with the GXL due to the wall being thicker, though the idea that a thinner wire would be more pliable as others have stated (TXL) might actually be the better alternative.
