Does anyone know where to get a . . .

[soletek]

I have a 1986 Honda CRX HF Federal Version that uses a five-wire O2 sensor Part # 36531-PE1-A02. American Honda responded with their favorite phrase: "That part has been discontinued." I have also checked all the parts retailers on line, including Majestic Honda of the South Bay, who does list the one I need, but doesn't have the item.

My question: Does anyone know where one might be found? OR, Does anyone know of another five-wire that might be modified without damaging this vehicle's ECU? Has anyone out there modified a five-wire O2 sensor successfully, and/or, Does anyone have information on the voltage parameters and internal connections of a five-wire?

This sensor has the smaller thread pattern than the five-wire sensors of today, but I can get past this since I already picked up a large thread pattern exhaust manifold off a 1986 that had the one-wire O2 sensor. If I could find out the wiring connections and voltages, I feel I can modify one to fit the purpose.

Thanks for any help!
