if the GREEN / WHITE and green are on the after market harness then that is for your left rear speaker. those vehicles sometimes came with the rear door speakers amplified with the amp under the driver seat.  take a look and see if your truck has the amp under the seat or not. if it does you need to give it 12v to the amp turn on wire for the rear speakers to work.

Thank you for the kvick ansver.The two kabels is in the original harness.the first row is power and front speaker and the sekond row  is rear speaker and the two kabels.I look in the morning under the driving seat . Tack så mycket
