Since vince doesn't post here much anymore I figured i'd spread this since a lot folks here avoid TDi Club.
It will also take an 8-32 machine screw die, which might be a little easier to find hardware for in some locations:
In terms of the factory harness...there was a model change somewhere in the 2001-2002 timeframe where VW switched from 2-wire harnesses to 4-wire harnesses, in part to allow plug-specific diagnostics. The old two-wire harness has been NLA for some time now, so anyone that repairs a 2-wire engine generally has to splice in the available 4-wire harness.
Or delete it entirely and run one's own wires...as heavy-duty as one's OCD requires. :-)

Did this on my 1.6, combined with separate fuses for each glow plug and the results have been great.

The main difference is the 1.6 glow plugs are already threaded.

I tried that on my mk2 but had issues with the fuse block being junk and just went to a single fuse coming off a starter solenoid. Going to wire my TDi glowplugs in series to a single 50 amp large maxi fuse to a solenoid. The TDi glow plugs are so easy to pull that I don't think individual is necessary except on the later ALH where they are wired individually from the harness. A 4mmx.7mm die also works to cut threads on the posts of the glow plugs as well.

You could just use bullet connectors.

I have messed around with those but I don't like them any of the ones I've found found deform when you put them on and take them off again and don't seem to keep a good connection. I cant find any in 12-10 ga wire. Cutting some threads will be a minimal task and a die only costs 4 dollars and will presumably last a lifetime.

The Ford IDI IH late 6.9/7.3 were bullet style connectors. How often are you removing your glow plug harness? lol

Those trucks have a huge issue with the connectors becoming loose, corroded, falling off and then the truck doesn't start. If you want one of those trucks I bet you could find one cheap right now that's it's getting colder usually with the phrase "ran great a month ago, can't get it to start anymore."

Over on TDIClub you will find tons of posts from people with corroded / failed glow plug harnesses. That's why Vince posted that over there in the first place. The factory push on connection is less than reliable.

WAY less than reliable, in my experience, hence good ole fashioned threads and nuts rather than press-ons

Well i threaded a "stale" glowplug i had laying around no issue with dislocating the post its shank can be gripped with a pair of pliers to cut the threads. Debating on spade terminals or ring terminals.

ring better then spade... and you figured out plier trick... just no break like shifter sir... you now know to support it..
