Hi, I'm new here and I recently got a s14. I need some help

What is that plug and what does it do?^


Where does this plug go?^

Does it hook up to here?^ If so then my wire isn't long enough..What do I do?

Also When I was changing the spark plugs the first cylinder spark plugs had oil on it, not flooded but it was pretty oily. What does that mean?

Was it converted to 5speed? The trio looks transmission related.

Seems like it's original 5 speed. The pedals, gauge, and gears look factory fit. I forgot to mention that the plug in the 3rd and 4th picture is hooked up with another wire to the maf on the intake. I think the reason I have the check engine light on is cause this plug isn't hooked up.

the plug in the first two pictures are for the automatic transmission pressure sensor. if your car was converted to a manual transmission then the plug isnt necessary. the plug in the third and forth picture looks like the plug for yur air temperature sensor which is supposed to be somewhere near yur MAFS. It dosent connect to the last picture.... it will definitely make yur car's CEL turn on if it isnt plugged in. yur air filter dosent have the proper adapter to fit the air temperature sensor it looks like..... lastly, if there is oil on yur spark plug it could mean a few things. possibly a bad piston ring seal since its only on one spark plug.

Can I just buy a new air filter to plug it in? Thanks for the info! Oh and sometimes when I start up or when I'm idle. I smell a little gas in the cabin. I have a gas leak?
