Progress report...Day 2 (cutting & splicing @ ICU)
Out with the old:
In with the new:
Today I cut out entire 2-3 foot sections of 7 seriously burned wires & shorter sections on 4 others. Every single wire
in that harness was affected. Damage stopped just short of the 1&2 injector leads, although I will inspect more
carefully tomorrow when I'm connecting at that end of the harness to be certain things there are clean & solid.
Another day in paradise...!!!???

When I replaced the alternator a month ago, for whatever reason, I checked those two connections. One has a black plastic protector on it, the other is bare. Both were so blasted loose I was surprised they hadn't already fallen off.  Cleaned them up, tightened them up, and reinstalled... good to go. But thanks to this topic, I'm now going to pull the bare connector back off and add some heat shrink just to be safe!

Must be a later production upgrade? My 86 is identical to Dave's (go figure)...
What year do you suppose the protector showed up? And perhaps the bigger question:
How many wiring harnesses have been fried for lack of that one insulated connector?

One wonders if Vanagons with power steering had a greater occurrence of burn-ups...

All I can tell you is that the parts catalog shows 2 in use for the MV (part #211971921) up through VIN L-045388. The peculiar part is, #045388 has a production date of December 31, 1989. Mine was built in February 1990 and has just one (certainly plausible one went missing over the years).
Brickwerks sells a retrofit: https://www.brickwerks.co.uk/wiring-connector-6-3mm-flag-white.html .
From L-045389, the vans allegedly came with a fuel injector-type connector (#357972752), which mine certainly does not have. 
Moral of the story: Who the hell knows...

I have a few of the white Tyco/AMP housings (same as the Brickwerks version) in stock if anybody needs them. $0.65ea plus actual postage.
This type of housing definitely can get brittle and fall off with age since they just snap together. A small cable tie might do the trick to keep them in place.

I've been using these "flag" connectors for some other projects & will do the same here:
Uses an uncommon crimp tool, but they're very solid & perfect for this application... 
Question all-of-a-sudden...any good reason NOT to use regular straight connectors?

The insulated flags are definitely difficult to attach correctly without the right crimp die.
The only reasons not to use a straight terminal would be if there isn't enough room or if it would put too much strain on the wire.

Thinking towards the end of this project...can I test the PS switch for possible internal failure?
Is the PS switch normally closed <or> open?
Home again, so back at this today...

OK...here's my page (NOTE/FWIW - LATE 86..."from VIN G 055 690"):
So...looks like normally open, & tests as such, so...GOOD!
