How do I hook one up if I have a single wired O2?
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)
rebuilding the engine with headers and heard there is a problem with keeping the O2 sensor at the right temp.
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
