Hi Frank,

So far, I've only felt the need to replace one heated oxygen sensor in many years, cars, and miles. That one was contaminated from the outside by a transmission fluid leak at the output seal. In that case, I used a full length replacement I'd obtained in a very lucky auction find. If I had to buy one, I'd probably get the one for the Ford Mustang 5.0 the board members have found cheap and abundant. Then I would look for and probably use the connector Ford uses to splice into my old sensor's wiring.

Whether you go direct replacement or splice in a universal, depends mainly on your individual comfort level with automotive wiring repairs.

Thanks for asking.
