Need help with lumbar...putting 2005 leather seat in 2011 Crovn Vic Police

I hope someone can help. The 2011 makes sense, 2 wires going to the lumbar motor (0,0 = idle, 0 +12 = fwd/out, +12,0 = rev/in). The 2005 has 3 wires going to the motor, one is constant gnd. The motor only runs in the fwd/out direction. Nothing happens in the rev/in direction. The switch is the same for 2005 and 2011 except there are 5 wires in 2011 and 4 wires in 2005. I have schematics for 2011 but nothing for 2005. Both seats are doing the same thing, so I don\\'t think its a bad motor. The 3 wires to the motor (black, brown, pink) are energized as follows:
No button pressed: gnd, open, open
fwd/out (motor runs): gnd, +12, +12
rev/in (motor doesn\\'t run): gnd, +12, open

Thanks
