I've searched but found various answers. Ok I have a 4 wire o2 sensor with an oem plug on it. It has 2 black 1 white and 1 grey. The pig tail on my jumper harness tells me where to hook up the white wire and the grey wire. I need help with the 2 black wires and where they go. I have the obo0 to obo1 jumper harnes from jhpusa.

Anyhelp would be great guys. Thanx in advance!

 

The 2 black wires should be the sensor heater. It doesn't matter which is which.

Hmm sorry I'm still confused. The jhpusa.com obdo0 to obd1 jumperharness says the grey and white wire are the signal and heater.. And it tells me what wire to hook up to the pigtail... It doesn't say anything about the 2 black wires. Where do those go?

 

Bump..

Black under the grey is heater -

No where. You trying to hook up a heated O2 sensor in a car that wasnt setup for it.
