wiring diagram for seat control module

[cartopics]

Can someone that has access to the wirind diagram on a 1999 boxster help me out? The driver side control module died, after smoke came from under seat. I was able to yank it out to notice the board fried at the p9wer input. I need to know which color wire controls motor movement. So I can try to move the seat while applying direct power to it. There are 4 wires to motor control: black, white, brown and red. Which ones are the positive and negative for motor adjustment?
