Vanguard EFI 49E877

I'm replacing a tired Kohler with a Vanguard EFI on a Bush Hog zero turn.  Is anyone familiar with the wiring?  So far I've only found one wiring diagram for this particular engine and none of the colors on the engine harness match what's on the diagram.  Any help would be appreciated.  I can't post a pic yet but the engine has the square 6pin plug with yellow/violet trace, green, orange/black trace, orange/white trace, violet.

    It appear that the yellow/red wire has been changed to yellow/violet. But the following is the pin out from the service manual.

    Thanks very much.  That's just what I needed.  Now as soon as the oxygen sensor shows up I believe I'll be in business.
