I just got this denso aftermarket o2 sensor and there is no harness on it, so i have to take the old harness and put it on the new sensor. Do you have a pic or can you tell me what the wires are on the original o2 sensor, ground, heater wire ect...

If not can you tell me how i can find out.

 

I don't have my O2 sensor in front of me, so this is going off the Helms manual:

Using this diagram, you're looking at the O2's connector:



The Helms lists the connector from the wiring harness side, so the coordinating wires on the O2 connector are:

Top right: (heater +)
Top left: (heater - )
Bottom right: (sensor + )
Bottom left: (sensor - )

Hope that helps.
