theres another sensor that is next to where this one is supposed to be.

im not exactly sure what its for, i believe for some sort of diagnostics , (kinda similar to the plug you have to ground when adjusting timing.but its not that) its not vital to the car running.

on my car this plug is there but is not used, i would not sweat it.

actually it has a place to plug it in. still not important? car runs without it. i just disconnected it to show you guys that one wire is loose on it, and was wondering if i need a new one or not?

well what plugs into it? follow the plug that it connects to and figure out where it goes.... i just know mine plugs into nothing ( same color wires too), its not the knock sensor i know that much. but yea- trace what plugs into it to figure out where it goes though.

I went out and found it on my 90 and it was still wrapped up from the factory un-used.

Per the manual, it’s for the EGR Temp Sensor.

it plugs into the back of the intake manifold right under that wire loom. theres two different sensors there, and this is one of them, but the wire is loose, the other is fine. which is why im wondering if this is something i should replace, or not worry about. the car runs without it just fine, but i havent pushed it to wot because i only have 200 mi. on a freshly rebuilt bottom end.
