How do I hook up my new O2 sensor?

[Mr.Puff]

How do I splice in this new O2 sensor? It has three wires; one black and two white.

Thanks a bunch ,

Mr.Puff

When you open the insulation on the existing cable, you'll see three wires -- two white and one black. The white wires are for the heating circuit and are not polarized. So, connect each of the white wires on the new sensor to a white wire from the car, and connect the black to black.

When I did mine, I put a piece of heat-shrink tubing over each of the individual splices, and then a big piece of heat-shrink tubing over the entire bundle.

Good luck!

OK, but you said 2 black and 1 white. My sensor has 2 white and 1 black. Do I just do white -> black and blacks -> whites?

Sorry -- I had it "bass-akwards." I've corrected my post.

[Mr.Puff]

Awesome , thanks for the help. This is for my '84 Targa... like yours.

If there's any risk of it rubbing off and the wires shorting, you'd be better off using heat-shrink tubing. The last thing you want is to risk cooking your DME box.
