I read somewhere on the net that two connectors (a green one, and a black one) could be connected together to see the history of warnings or whatever..

I had a little look under the steering wheel and it was tons of cables there.. I found two black and two green connectors that wasn't connected to anything, but i didn't want to mess anything up so I figured i'd post this message here to see if any of you guys know more about it..

So, if anyone know exactly what two connectors that should be connected (I have the subaru wiring diagram if you could make a reference to that) i'd be very happy..

Btw; It's a MY99 Impreza GT
