WB O2 Sensor Connector Again

Well,  I visited our local import car junkyard in a quest for finding the
mating connector for the WB O2 sensor connector. It turns out that the
junkyard strips all engines from Honda wrecks to sell as cores for
re-building.........and they take all the engine wiring harness with them
so no exact mating connectors were available.  However, as some of you
suggested, there was a similar connector on the passenger fenderwell.  This
connector physically mates but is missing one pin.  The pin missing is
where the calibrating resistor is molded into the sensor plug. It seems to
me that I can mount a matching resistor directly on the circuit board
instead.  My DVM says the molded-in resistor is 11.81 Kohm.  I suspect that
a 1% tolerance resistor would be sufficient here.  Any comments anyone?  Am
I missing something here?
