Hey everyone,

So I'm installing my PPE headers soon and have some questions on the secondary O2 sensors and the O2 conditioner. You may be aware that the PPE headers come with O2 sensor extensions that work for the primary O2 sensors but I'd like to possibly buy a second set and use them to make a plug-and-play harness for my O2 conditioner rather than hook it up in the engine bay. I would use the extension in btween the O2 sensor connector and the main wiring harness and splice the O2 conditioner in the extension rather than installing it in the engine bay by the ECU. However I some questions that I could use some help on

1. Where in the interior do the secondary O2 sensors connect to the main wire harness?

2. Do the secondary O2 sensors use the same connectors (size and type) as the primary O2 sensors?

3. Does anyone see any issues with this?

Thanks in advance!

Regards,

Kyle
