need some help!!!!!!!

only one plug im having trouble with, this one...
its a blue/white plug that doesnt fit... motor and harness are from 99-02 and my truck is 03, i wanted to keep cable trottle body. but these plugs do not fit nor have the same wire in the correct spot... also the truck side of the harness has 8 wires and the motor harness has 7, the only wire different is on the truck side which is a brown/black.









this is in big_countrys 04 silvy z71 notice both plugs are white....



DO I HAVE THE WRONG HARNESS?
