      Gm 4L80e old style connector and wiring color code

      I am helping my neighbor who was working on changing out his flywheel and the transmission dropped which caused the system control wiring to separate at the connector from the transmission. I have researched and all I can find is a different color code for this connector. I will list the colors that I am looking at and hope someone can help me........ help my buddy.
      1.red
      2.yellow/black
      3.red/black
      4.violet
      5.blue
      6.tan/black
      7.green/white
      8.pink
      9.black/green
      10.green
      11.pink/black
