wow, that's saying something .........
if you consider it toke-worthy to have discovered after all this time that
it doesn't matter which injector wire you plug onto which injector on a
waterboxer vanagon engine.
You can also see it in the wiring diagrams,
for example on page 97.106...........
it shows one white wire connecting pin 12 of the ECU to all four injectors.
As long as we know they don't digitize or 'can-bus' 4 signals  on that one
wire ( which they don't of course ) ....it shows right there that the ECU
fires the 4 injectors as one big injector.  And it does it by supplying
ground to them to energize them, like one big four-part injector.

and it would be shocking to think something worked one way for 20 years,
only to discover after all that time it's different than you thought !
Welcome to 2009 - lol !    :-)
