Mystery connector! WTFlingin flangin is this thing!

KillerBMotorsport · 04-04-2014, 03:42 PM

I'm stumped... Not PCV white hose plug thing, not TGV. All cam, and solenoid plugs are in. Pulled the manifold off this car 3 times and for some reason this time it's hiding one on me

This pic of looking at the passenger side fuel rail.

Any assistance highly appreciated!

daytime running lights?

KillerBMotorsport · 04-04-2014, 03:47 PM

No, that one is in the fog light area, although disconnected

I don't think that's part of the engine harness?

bigolrig · 04-04-2014, 03:50 PM

ahh okay, on my bugeye the DRL box and plug were on the passenger strut tower

Fender137 · 04-04-2014, 03:50 PM

Look's like that could be the Flux capacitor plug.

KillerBMotorsport · 04-04-2014, 04:06 PM

^ nope, that one's already plugged in.

PCV Diagnosis Plug?

Nuke209 · 04-04-2014, 04:24 PM

Year? Model?

egt sensor

CTSparky · 04-04-2014, 04:55 PM

that sure looks like it might be to the cam sensor.

bikerboy · 04-04-2014, 04:56 PM

Thant looks like the PCV connector as it has the plug mount on the bottom that locates it on the inlet pipe. What does the plug look like that is currently plugged into the PCV ?

sidewayz · 04-04-2014, 05:18 PM

its egt guys..

cam sensor is a 3 wire. pcv connector is in the front of the motor on that year

Motion Machine · 04-04-2014, 05:18 PM

Easy, that's the prefamulated amulite module connector that senses the articulated oscillations of the reciprocating dingle arm...

Sti's don't run EGT sensors.

fastblueufo · 04-04-2014, 06:08 PM

That goes to the pcv air thingy thats on the turbo inlet right in front of where inlet connects to turbo. The blue plug in that pick going to the area in front of turbo is goes to the avcs solenoid on top of valve cover.

It's looks nearly exactly like it, but that PCV connector is already plugged in.

Here they are as close as I could get them to each other :/

I wish I was. see pic above

sidewayz · 04-04-2014, 06:38 PM

I know no egt... But don't they have a bare plug just chilling? I could have sworn they do

ALOKIN · 04-04-2014, 06:43 PM

I just went out on my 13 and had a look. It looks like either the cam sensor or the pcv open sensor. You said both are accounted for so I am at a loss. It looks like it comes off the loom were the FI connectors do, if so I don't have one of those on my car. IS your O2 sensor plug accounted for?

The cam sensors are a different plug type so no chance for screwing that up unless you're out to break something

I pulled the PCV sensor off and it goes into both connectors and I can't see any difference in the plugs. I don't believe the PCV sensor was even removed from the harness since it wasn't connected to anything already.

Thanks for the effort guys. Anymore ideas?

dangerousatom · 04-04-2014, 07:00 PM

What wire colors are they? It sounds like all the possible plugs have been mentioned or accounted for. The only one in the STi diagram that is a weird and gray 2 wire is call the "leak diagnosis connector"
-plug #E80
-page WI-139 in the manual i have.

The wires in your pic dont look long enough to even make it to the PVC plug

bswilmington · 04-04-2014, 07:19 PM

KB it looks like you got the blue AVCS connector plugged into grey connector in last pic you posted?? You sure that's connected correctly? Shouldn't it be plugged into AVCS solenoid on top of head and maybe this mystery connector plugs into that one?

Or you could do easy thing of cranking the car to see what codes are thrown if all else fails

KillerBMotorsport · 04-04-2014, 07:21 PM

E23 and E17 are the plugs. E17 is the one I can't find it's mate.

E23 is white and black w/magenta stripe

E17 is white and light blue w/red stripe

The blue one in post 18, in the background. That goes to the EBCS.

Cam solenoids have blue connectors, cam position sensors are grey.

Thought about cranking it, but I'm still working on the fuel system and this is just eating at me in the mean time!!
