So i got this del sol that has plugs on the harness cut off so there is no O2 plug on it and I cant seem to find where the plug was. yes I have searched alot cant seem to find any good info though. So i need the find where to run the pins/wires on the O2 to the ECU.
Do 2 of the wires go to ground?

thanks for the links, but i need the same kind of diagram for obd1, and I need a pinout for the sensor itself
thanks

 

The sensor should be 2 blacks, a white and a blue (or white and a green, depending on company). The two blacks are the heater positive and heater ground wires, the white is the power source and the blue (or green) is the signal wire.
