Look at what I was looking at on 97.63 and show me where the left tail light
and right front parking light are on the same circuit and connected to fuse
S2, which is the actual "as built" condition.
There are no PO mods to this rig, which is one reason I bought it.
There is no comparison between these chicken scratchings and the later
wiring diagrams, which are MUCH better. I feel I'm pretty much on my own
after this experience.

All years with the old panel (pre '86) show left side front, tail, side
marker lights fed from S1; right side front, tail, side, plus license plate
lights fed from S2.
Front markers come directly from the fuse. Side markers are vampired off
the tail lights, double wire at the taillight connector pin.
Taillight '82 and previous (and according to the diagram, '83 aircooled),
both sides fed from second spade terminal at load end of panel fuse through
four-pin connector connector T4b (along with alternator D+ and maybe
something else) located at fuse/relay panel.
Taillight '83 and subsequent fed from second spade terminal at load end of
panel fuse through pins 5 and 6 of seven pin connector T7 in wiring
connector box in the engine room. The connection through T7 pins 5 and 6
persisted through the end of Vanagon production.
(All above from July 1991 edition of Bentley)
Now looking at that, I have to wonder about the location of T4b on the
earlier diagrams. Evidence from the D+ line suggests that it's probably
actually located in the wiring connector box, in which case the change to T7
in the same location makes sense in terms of not drastically rearranging the
wiring harness. But that doesn't affect your year.
If your wiring was actually significantly different from that, I suspect the
DPO had made some changes. If you fixed both left and right sides by
putting one terminal back on the fuse/relay panel, then without question he
did.
