M20 Conversion / Ford Mustang Oxygen Sensor Question

[punchesdfw]

I've searched the archives and kind find the info. I remember something about a Ford Mustang O2 sensor that would work with the M20. Does anybody know? The M20 O2 sensor is welll over $100!

U might try a bosch universal sensor. Probably the 3 wire one.

The Mustang sensor is the 89 5.0 long lead, it's a 4 wire.

They come in one, three, and four wire variants. The one wire relys on being close enough to the exhaust valves to get it to proper temperature, the three and four wire variants have heaters so the sensor can be further away. The one and three wire sensors rely upon the chassis for the return path (ground), the four wire sensor has a separate ground wire.

The bung size is the same for all, get the cheapest GM sensor you can find.

Cheers!
