Okay, this will be a little difficult to understand/explain:

I'm adding a/c to an 87 vanagon and, as part of the update, I'm updating
the radiator fan to the huge one used as stock on 86 and newer vanagons
with a/c.  This fan uses a resistor (located behind the driver's
headlamp) to cut its speeds down.  I need the wiring codes for that
resistor.

Bentley says which wires go to it, but the resistor's wire and harness
are all the same color.  So I need someone to check theirs and let me
know which wire goes where on the three-connector harness used on the
resistor.

You'll have to do something like:  with the fan resistor's harness
disconnected view it head-on (looking at the terminals) with the single
connector on the top

the top connector gets color X from the van
the left connector gets color Y from the van
the right connector gets color Z from the van

The top one will be easy to figure out but the left/right need to be
unambiguous.  Obviously a picture would be worth a thousand words here.

If anyone has the energy to get this for me I would REALLY appreciate
it!

Thanks,

Damian
