Blau Wire Harness

Using the Blau harness saves some time, for the price and time saved
measuring and building up your own I went for it.  If you have the
time and the desire/skill, you could definitely create a better
design than what they sent me.

Some connectors weren't right, the running/parking light feed had the
wrong connector.  You also need to check the pinout of the headlamp
assemblies since they aren't always the same from unit to unit.

I plan (don't ask me when!) to modify my Blau harness to re-enable
the lamp monitor; Blau only uses one of the old connectors to
control the harness.  I plan to add a second low-beam relay and
some diode/resistor shunts to provide some current draw on the
original wiring to the bulbs.

Anyone who cannot cope with Mathematics is not fully human. At
best (he) is a tolerable sub-human who has learned to wear shoes,
bathe, and not make messes in the house.
