Maybe your truck doesn't have an EGR? Might just be wired for one. Take a pic of your exhaust side of the engine at the manifold. Also there's a "model number" somewhere on the door sticker. I can decode it if you want to know what the cab's factory setup was (not the VIN).

It's going to have an EGR. California models in the late 80s - early 90s had a temp sensor in the EGR that would inform the ECU that the EGR was functioning properly. If it did not get this signal, you'd get a check engine light. Non CA models didn't have this sensor. Shortly after 1990 most of the trucks started having the sensor. I imagine that Toyota saw this change coming and started producing a standard wiring harness that included a connector for the sensor even though not all models had the sensor yet. My 89 does not have a sensor or plug.

Interesting, I see the single set of tubing, but not the double set like EGR trucks have, so I'm pretty sure you don't have the EGR. I'm not super on top of that area of the engine though, pretty sure one set of tubes is used as a intake warmer for cold starts (atleast on the carb model I think that's true).
Model is RN130L-GKMSEA
RN130L is basically a code for your engine and truck/chassis setup, left hand drive, the number changes for standard cab, xtra cab, long box etc
G - Wagon/Van (So I guess this must be a 4runner?)
K - This should be "body type" but I don't have a listing for K, maybe it's a 4runner dedicated thing
M - 5 speed floor shift MT (makes sense since you have a W56 trans)
S - SR5
E - EFI
A - Built to be sold in USA
The model number didn't have the C after the grade, so it isn't an "Emission Control" model which I suspect is dedicated for CA trucks, or maybe more generic for ones with EGR. If it had the C it would have ended up being GKMSCEA which a google search suggests doesn't exist.

Checked codes (engine light is not on) i have 41 which is TPS (probably from when it ran low on water after my radiator blow a couple weeks ago and it started surging crazy), but thats it. Probably no EGR im guessing??!

The first image shows the egr inlet, the valve, and modulator. It also shows the spot that would be tapped for the egr temp sensor and its not tapped.
The definite way to know what that plug is is to probe between that plug and the ECU end of the engine harness. With both ends disconnected, you put your multimeter, set on continuity mode, into each of the unknown plug wires in turn and probe along the ECU plug.
