Help Identifying a Plug
 

I have started the process of replacing my fuel lines and fuel rail (As well as regulator and dampener - They all went kaput), and noticed this plug just hanging out underneath it all when I removed the rail.

The car started, ran, and drove just fine before - so I'm not entirely sure what this plug connects to. It's not my cruise control, as I've already removed that.

Any thoughts? Should I just cap it and move on? Any help would be appreciated.

Move on

There is a vacuum line (looks like its for the FPR) on your middle finger (as you already may know).

The plug in your hand looks to me like the O2 sensor plug (the other end might be hanging down near your exhaust/bellhousing) - although my S2 O2 sensor plug has 2 male and one female prong, whereas this is 3 male pron

Thanks - Yeah, I thought it was O2 as well, but my O2 is plugged in and exists down on the exhaust housing. I'll have to dig more and try to trace this back to where it start, but perhaps Rasta Monsta is right - I just leave it and move on.

That is an old diagnostics plug that is obsolete. The dealer used it for testing purposes. Shove it somewhere you'll forget about it.

Diagnostic plug. Harmless.

Awesome! This is why I love this forum.

Thank You!

Thats pretty cool, a diagnostic plug for an older car. My 961 has a port on the drivers side near my master cylinder, just all all 951's...cool chit mang!
