UVCH tricks
I must admit, im not using motorcraft gaskets and wiring harnesses,
but I did get them from Napa.
the driverside wiring harness keeps coming loose.
this design has got to be the @#$%#$&^ worst ever.
I love engineers..........(slams beer)
im thinking about JB welding the wiring harness to the gasket...
ON THE OUTSIDE of the connector.
what else can be done to clear up this issue.
verified by running the pins with the IDM disconnected.
nothing before I took it apart,
pulled the cover, wiggled the connection, and they are now within spec in the 3.0-3.6 ohm range.

The updated harness isn't supposed to come loose. Typically the connection comes loose on the inside of the connector. Is yours coming loose on the outside? Is the little tab that is supposed to hold it in place clicking in like it's supposed to?
If it's the inside connector, there are plenty of options available. If it's the outside one, and you don't mind making it permanent, clean it up and use super glue.
Edit: When I say inside vs. outside, I'm referring to the connection either underneath the valve cover (inside) or the external connector outside the valve cover. If it's the internal one, there are plenty of solutions.

my apology for the indiscretion.

And yet you're thinking JB weld to compensate. We've all done it at one point or another - pour our blood into the engine to keep a little extra treasure close to our butts. That's how we learned not to do that again. The Dorman one-piece may be a rare exception to the rule because it completely eliminates the part in question, but that doesn't say anything about the longevity of all the rest of the part.

it may seem petty, but the 400 dollar price for OEM's are hard to swallow.
but then again, taking this thing apart is getting really old.
I have used the dorman 1 piece gasket/harness.
lasted about 7 months before the shielding on the injector wires cracked and broke.
creating hi/low issues.
I love these engines, but this part of it has gotta be the death of my soul.
ive even contemplated throwing a IDI in the damn thing.
but im in commiefornia, and it will still need to smog.
im curious if anyone has ever modded the valve covers and used a weather pack connector on the top of the valve cover with better wires and easier connections.

Unless you're desperate, never go to the Ford Parts Counter and trust their pricing. You can get the same OEM parts online from other Ford Parts sources for typically 30-40% LESS.... but you WILL have to be ready and able to wait on shipping times.

If the OEM UVCH was as great as what some here think it would outlast valves and piston rings.
Face it, the design of our injectors and the electronic controls (specifically the UVCH) are entirely inadequate to last half the expected 50% life of the engine! "Engineers" decided that these parts are "routine maintenance items" and that most buyers would trade in @ 100k.
Makes sense to the marketing idiots, but defeats the reason most of us went with the 7.3.
Ford FAIL - as has been every diesel they have produced since (most with more significant shortcomings)! God forbid Navistar or Ford apply the criteria that made the old DT466 medium duty diesel dependable over a couple million miles to a consumer PU that cost nearly as much.
Still, the 7.3 in spite of her faults, is the most suited to my uses, and I intend to run her till she goes **** up!

I used a couple of quarters as shims over 10 years ago and haven't had any loose connections yet.

Well, you're almost right. The engineers are not the ones who decided that these are routine maintenance items... that designation came from the accountants and lawyers! The engineers have a pretty good idea what the true life cycle for parts really is, but they just don't get a say in how the manufacturer ends up deciding to market and warranty the stuff.
