yup, easy as...
the heater will have a resistance of about 4-6ohms usually. there is open circuit from heater to the signal wire.
the two heater wires are usually the same colour as there is polarity to it, it's just a resistance heater.
so, find the two wires with about 5 ohms resistance between them and they are the heater, and the other one is signal. make sure that you have a very good ground from the exhaust to the ECU ground point, as the signals ground is the body of the O2 sensor. if you have a shitty ground, the readings will be incorrect.
fyi, the 4 wire ones i have (both NTK and Bosch) have two white wires for the heater, a grey wire for signal ground, and a black wire for O2 signal.
Cya, Stewart
