Thanks Fisherman. Are you in Bend? I like central Oregon a lot.

I did some study on the seat bottom. Here is what I found:
Pin1 (Orange wire), Pin2 (Gray wire) for seat back
Pin3 (Purple wire), Pin4 (Blue wire) for motor#1, fwd-backward
Pin5 (Yellow wire), Pin6 (Green wire) for motor#2, back lift
Pin7 (Black wire), Pin8 (White wire) for motor#3, front lift

I pull the cable ends from motor#1, and chuck the ends to a cordless drill. The seat rail can be moved forward and reverse by the drill. Very smooth action, and does not take much power.

I maybe able to use the seat bottom, just replace the leather cover.
