anybody know hot to match up the wiring from 2 different o2 sensors i have 2 black a grey and a white

im converting to obd1 and the instructions are for a 02 sensor with 2 whites a black and a green

any help is appreciated its the rywire conversion harness

 

should be plug and play...

but you might be using a differant Obd2 02 sensor

 

the wires that are the same are the heater. it doesn't matter which way they are connected in relation to each other.

the other two are the O2 sensor itself.
the stock OBD2 O2 has white as the positive side and light green as the negative side.

logically the green is the positive side and black is the negative but the only way to know for sure is to trace the wires.
the positive side should run to D14(O2 signal input) of the OBD1 ECU, the negative side should run to D22(sensor ground)
