[200q20v] Blau wiring harness for new Bosches seems miswired

We had a sunny weekend here, I popped the new units in on Sunday.

I missed the warning ( was there one ? ) about the euro units hitting
the battery jump terminal on the passenger side, among other issues.

After finishing as the sun was going down, I began testing.  The
normal beams seem OK, but the driver's high was dead.  After going
back out in full dark to check out the road-going improvement of the
low beams ( wonderful! ), I noticed that it wasn't the driver side
city light that had been coming on, but the hi-beam at a low power.

Since the lows seemed OK and they are good enough for normal highway
driving, I haven't yet futzed with this any more.  I have to go back
in and change out a last minute add-on to deal with the wrong part
that Blau put in the harness for the city lights, they provided a
connector for and described a plug that didn't exist on my car.

My question here is are the plug contact positions in the Bosch
assemblies the same on each side or mirror images ?  The harness
instructions did not include a schematic and only mentioned that
the blue and brown wires should be at the top of the connector.

I threw my Fluke in the glove box and might get a chance to diag
this for lunch today, but would appreciate any correct info that
would save me a bit of time.
