True forgot about ebcs being blue. How about evap solenoid? Is that plugged in?

On the front of the manifold, fuel purge, etc.? yes

BeastianSTI · 04-04-2014, 08:36 PM

What year of harness / engine? All are from an 05 STi, right?

KillerBMotorsport · 04-04-2014, 09:06 PM

2012 STi

bswilmington · 04-04-2014, 09:47 PM

Yeah I actually see in the on pic now the purge solenoid connected.

According to the Subaru FSM there is only couple things with grey connectors with 2 pins
Fuel injectors
Knock sensor
Crank sensor
And apparently 2 Leak diagnois connectors

What the heck is a leak diagnostic connector? that stupid PCV thingy. there are two?

Yeah it's that stupid PCV thingy haha. I've never seen car with 2 but then again I have not had the intake off 12 Sti yet. Wouldn't surprise me to see 2 as the harness shows 2 in this break down

Theres one near the turbo then one in the front of the manifold

KillerBMotorsport · 04-05-2014, 11:01 AM

Well now I feel dumb. one for not knowing and two for pulling this off a couple times already and never noticing two!

Thanks guys, really appreciate the help on this!!

As I get it the ECU wants to see this "Leak Diagnosis Connector" as a closed circuit, as in "the PCV hose is installed".
I am dieting the harness on my 2009 FXT and I am doing a custom fuelling system, installing Cosworth TGV deletes, and adding an A/OS.
If, when I get it tuned, can this be turned off or does it matter?
Seems like the simplest thing would be to put the two wires to the connector together (so the circuit is closed) and eliminate the connector since I will not have any of the smog or evap system.
