yup! did mine when I was upgrading my speakers and radio, I said huh! what is this doing unplugged, plugged it in and my check engine light came on oh, NO!! Then I remember that I had plugged the two green connectors and unplugged them and restarted the SF and bingo light off. What was weird was that the light would flash and not stay on constant. But I knew something was not right.
Boy I'am happy I found this forum.:woohoo:

I just got a '10 Forester X, Right Hand Drive. Was looking around under the dash when I found these green plugs. Remembered reading something about plugs.....somewhere. Took me a while to find this thread again.

On my car they are on the left (passenger's) side just under front edge of the carpet.

Same thing on my 2010x Passenger side. Just saw them when installing the blue footwell lights. First thing that came to mind was "Hey some other accessory that I can install must plug into them. WRONG.

Almost all subies have the green plugs; some on the left side, some models on the right. They arrive from the transport truck with the plugs connected. The "Pre-Delivery" inspection requires the dealership to disconnect them. I believe having them connected prevents the car from learning its enviorment (ie altitude, temp.) until the car is at its selling dealership.
During some testing procedures, and during a reflash of the cars computer we may reconnect them.

Cars are full of unconnected connectors, since they tend to use one standard harness across a whole line, ready to accept whatever options or model-specific items might end up being installed. And yes, they do sometimes get fouled up.

How amateurish! Those plugs are only weathertight when connected. I would never let one of our electrical guys deploy something so unprofessional.
One would think that some sort of plug could be put on these to keep them closed. Also, it would be nice if this was addressed in the owner's manual or better yet with a small label on the plug.

Something subtle like:

DON'T CONNECT THESE PLUGS!

Something like that so that even I can understand it. These are the types of labels I can appreciate:icon_razz:

lol pretty sure I bought mine with these connected. Keep getting weird codes and when in ACC the fans, relays etc are all tripping out. I will go take a look and disconnect - forum win!!!

Heh, I recognise that plug from the EA81 era :biggrin:

That used to be tied to a service interval timer way back when: every 60,000 miles it would turn on the EGR light on the dash. IIRC, there was a connector under the dash with two positions that the plug could fit into; you'd just swap it over to the unused spot and the light was out for another 60,000. Lather, rinse, repeat every 60K.

Funny to see how that carried over through the years, even if its purpose is just slightly different now :icon_wink:

I noticed 2 disconnected green plugs in the footwell area on the passenger side of my '11 - are these the same thing? I assume I should leave them disconnected? Especially since the vehicle is running great, LOL.


Thanks,
Mark

Thanks for confirming the 2011 has them still, and yes do keep them unplugged.:icon_razz:

My turn to ask questions! well just one. Should these be CONNECTED for a diagnostic check or do they just send the car hay wire? Do they show up real codes or just make random ones show?

Is this down near the blower housing? I was just down there pulling out the fuel pump relay plug for my compression test and see that it is connected, and has been connected for 13,000 miles, with nothing out of the ordinary...just the annoying emissions related CELs.

I found those little green plugs today while reinstalling my car's carpet. Connecting them resulted in a flashing check engine light as well as the cooling fans cycling between off, low, and high. I'm glad to know that they're supposed to be unplugged!
