Hi everyone.. I just bought a 2005 Infiniti g35... There are a couple of plugins that are not hooked up on my engine I'm going to post a picture if anyone could help me to find out where these go I would appreciate it thank you This wire is in the same harness as the coil wires.. I don't know where it goes... Have one other picture I'm going to post
Top wire doesn't look like factory equipment, chase the harness down and find out where the other end goes.
Bottom wire with the green harness looks suspiciously like the downstream O2 sensor harness... plus I see some cable ties further down in the picture so it looks like it might be the downstream O2 sensor that someone brought up into the engine bay for REASONS?
Wiring help can be tricky, especially when trying to add tech features that are not standard. While the forum focuses on automotive wiring, it’s interesting to see how apps like https://wellness-app.com/ inspire health-conscious innovations. For example, a fasting timer app is becoming popular for tracking intermittent fasting, and integrating such technology with car systems could be a future possibility. Although this forum is about wiring, keeping an eye on health apps like and tools like a fasting timer app can spark ideas for combining wellness and technology in creative ways.
