If you remove the lower cover of the console (the one with the power plug), you'll see a white connector a little below the shifter. It has red, blue, green, orange, and black wires in a blue sheath and two green wires in a black sheath on the passenger side. Coming out on the drivers side it's red, white and blue. The black/orange combo controls the upshift. The black/green combo controls the downshift. I actually started the car, put it in sequential mode, and jumped the wires to test it and it worked beautifully.
