Subject:O2 sensor heater wiring
From:Geza Polony

Good folks,

I'm wiring a 4-wire O2 sensor from my Saab 9K into the '84 Vanagon, since
it's the same part number as the sensors for the '91 and should therefore
put out the right signal. Looking at the Bentley 97.72 it appears that the
heating element hot wire is to terminal 86 of the fuel pump relay but I'm a
bit confused by the diagram. Can anyone tell me if this is correct ('86 and
up?) I don't want  to overload any ciruits by adding this in.

thanks

Geza

BTW the V already runs better with the new/used sensor, even without the
heating element hooked up...
