Heated O2 Sensor

I think there is just another ignition wire that needs hooked up, and PERHAPS a ground wire.

Why are you installing a heated one? Are you experiencing problems with the one you have now based on it cooling off at idle? (Even the GM manual says this can be normal though)
 
I bought one for headers, but haven't installed them yet. You are supposed to hook up the extra two wires to a 12V switched wire and a ground.
 
Get headers with the O2 bung if you can, if not, weld it in right after all 4 tubes join.

I'm not running a heated one on mine, and have no problems with closed loop. Run what you have, THEN if there is a problem, go with the heated, unless you have to replace the one you have now and the price difference is justifiable.
 
I agree, definetaly try what you have first. I had bought one for my iroc when i put headers on it, tried the old one first, never had a problem, returned the heated one and saved me some moneys
