I am installing a heated O2 sensor in my 82 and need some ideal as to where to hook up the power and ground wires. I know it needs key on power, just not sure of the best hook up place. Anyone here that have done this on an 82, I'd especially like to hear about your connections.
Thanks

What is the advantage of a heated O2 sensor?

The stock one is not heated, why change it?

Why do you want to install a heated sensor? It will provide no benefit whatsoever. The original type non-heated sensor is all you need.

Heated O2 sensors respond quicker, or more accurately, get up to operating temps quicker. This, in turn, allows the ECM to go into "closed loop" operation quicker, which gives it more control over the emissions aspects sooner. The sooner the ECM goes into closed loop operation, the sooner the air/fuel mixture is adjustable/controlled by the ECM.

I don't think you can just wire in the heated elements to key-on power. That will cause the sensors to basically explode eventually. The heated sensors are normally controlled by the ECM, and are only heated(on) for a short while, until the exhaust is hot enough to keep them working. I'm also not sure what voltage the ones you have work from...may not be full 12v.
All that being said, I can't see the need for them on your '82.

I'm sure Ken can 'splain this more...and make more sense of it...

I am double checking on the key on power connection. My problem is since I have installed headers, the o2 sensor is not getting up to temperature, which I think is 600 degrees. This is causing it to go in and out of closed loop and running bad. Installing the Heated sensor is what others with the same problem have done on their 82's.
I will keep you posted on the results.
Thanks!  

Joel is correct in the need for the heaters.   And with the headers, the need for a heater makes sense.

You forgot to mention having headers!
The O2 sensors staying too cool to operate properly on headers is usually due to them being too far away from the heads, where the real heat is. If they are mounted on the collector, that's not the best place for them. You might consider moving the sensor(s) up farther towards the head on one of the tubes. That would prolly make it work fine, without having to go thru the hassle of wiring heated sensors...
Of course, that would mean the sensor is only getting a reading from one cylinder, too...not exactly the best thing....

I got the heated O2 sensor installed; I ran a power wire to the radiator fan power, 12v at ignition ON. I used the right gauge wire, used 24" of 1200 degree insulation sleeve to run the pwr and sensor wires to the engine compartment, soldered all connections, heat wrapped all wires and made all good and non-bubbaish.... The car runs much better at the lower engine speeds thanks to it getting into closed loop way faster. My O2 bung is presently located about 10" from the header collector; that is 10" from the end of the collector. When I install the new exhaust, I will move it to the collector and still use the heated O2 sensor.
Thanks for the help guys!
