Ok...its the little green board yer talkin' about right?
With the thing apart, upside down and wheel facing away from you:
Top side L-R: Or, yel, grn, blu, wht (these wires come from JP6) blk, brn (from JP4)
Bottom side L-R: Or, yel, grn, blu, brn, wht, blk, vio/wht (wires come from wheel mech, the wht wire comes from the shift stick and ties to the same solder pad as the violet wire does)
That should take care of it.
Now....since I've helped you out, you can do something for me if you can.
I got the wheel without the pedal assy so I have to adapt another to it. Can you detail the wiring from the pedal pots to the JP1 connector? You should be able to do this with a meter set to continuity beep.
