1 wire Vs. 3 wire OXS

[tiAn@usiw.net (Christian Els)]

The only connection that really matters is the signal wire (black). The
other two are just pumping 12V through a resistor to heat the works up.

If the Bosch-trained guy around here (Dave Ewing? Chris DeLong? I can't
remember...) is right, they are supposed to be spliced connections anyway.

Cheers,

Christian
