Need help on the dash, or I will start at the start.
I found a black plug and a green plug by the driver footwell. I plugged them both in then started up the car. The cheque engine light came on when I pulled out the black one it did not come in . Green one still plugged in . So I don't no wot to do . I have left the green one in . But unplugged the black one . Any help

 

These are the connections for reading codes, they are meant to be disconnected.

 

Yeah both should be disconnected.

 

Don't forget to put the guarantee number on the back

What do the guarantee number on back mean. Not sure what that means . Thank for all the help . When I looked under the wheel I just see two plugs one black one green . And as the other end was by them I just thort they come loss . Cose when I put the together the black one put the warning engine light up on the dash. So I pulled the black on out , & it went away. I still have the green one together so I will pull that out tomorrow as well . Thank u all of u . Dam u lot no your stuff
