Hi there, in an attempt to figure out why my OBD2 device won't connect with my car, I've done some looking around and I have found something (shown in the picture BELLOW) and I was wondering if anyone here could please help me figure out what on Earth these two unplugged cables might be for.

 

 

I figure that, since the cables are UNPLUGGED, maybe they are that way because they were causing a problem, therefore I figured it's best to ask for advice. (I'm notorious for innocently destroying things)

 

The wire on the female side of the connector is BLACK and BLUE. oh, and it's just a single wire on both sides.

The other side is red and blue (if that helps)

If you're having trouble finding it in the picture, the connector in question is directly in front of the BIG BLUE connector, right in the middle of the pic.

 

 

 

Any help is appreciated!

not certain about black - but good chance those are only used for some type of diagnostic/reprogramming routine. (TCU ?)

 

You may also find 2 green connectors - those are definitely used to cycle relays and fans as a test, and are 'normally' disconnected.

 

 

someone will have better details.

I'm not 100% the diagnostic connector for fans, relays etc is always green, but it is always under the drivers side dash- where are these wires?

How bout Year? Model? Engine? 

Yea its under the drivers side dash

 

99 Subaru Impreza 2L non turbo. (GL i think)

 

 

 

 

I did see other posts around the net about 2 green connectors, and horror stories to go along with them lol.

Mainly about the horrible feeling people got when things seemed to go haywire when they put the two together, ha. Exactly what I was avoiding I suppose.

 

Anyway, I basically just wanted to get one of those bluetooth obd2 connectors in there all the time so that I could then use it with a smartphone app and make my car look and feel cooler =P  (Although, Currently I have my hands on a normal wired obd2 device. not using a smartphone to hook up to the car yet)
