How is your heated 02 wired?

[Matt Weiser]

I'm thinking of installing a heated 02 sensor. I have an old plug-n-play kit that I bought used and the connectors don't work on my car (must be for an earlier car or something). So rather than rewire the connectors, I figured I'd just hook it up to 12v and ground. So I'm wondering if anybody else has done this and if you can recommend a convenient place under the hood to connect it for power and ground. Thx!

You can tap switched 12V and ground from the fan delay relay to run your heated o2 .
The wire colors on the connector are black&white (for ground) and red for 12v switched (positive)

Thanks, I'll give that a look!
