What am I? What do I do? And does it matter that I don't do it?

[That Guy]

This!

 

 

Drivers side above the head. It has a hose to the crankcase, and what appears to be a plug (white thing) on the end. To be fair, I haven't actually checked to see if this, in fact, is an electrical plug, however, I did check to see if I had any additional loom that could be for this thing. Alas, the answer is no.

 

Should I be concerned?

[SpeedySub]

At a guess. I was thinking some sort of oil pressure and temp sensors. 

[That Guy]

Yea it looks very sensor like. I really don't have any idea though. Perhaps I best have a thorough look at it first

I'm going to say it's the oil pressure sensor. Two in fact... the small one is the factory sensor, the other is for some gauge.

Yup, oil pressure sensor. Had one on my RA (now @SpeedySub's, you should see it under the alternator)

It's definitely after-market, and most likely for a Oil pressure gauge that would have once been in there.

Yeah Thats what I noticed on the RA, and why my guess was pressure with maybe a temp sensor as well.

Def pressure... not temp.

Another vote After marked oil pressure sensor, tee'd into the oem position under the Alternator in front of the motor, had similar setup but with less joiners

 

bigger picture might have helped locate it eh
