The car is a 1989 Oldsmobile Custom Cruiser, which is the full-size
station wagon. The six-way power seat switch in the door handle burned
up, taking the plug with it. I need the part number for the switch. I
doubt that a part number is available for the plug only. Is there a
short stretch of wire harness that can be replaced here? There was a
switch on eBay lately; the seller said it fit several model B and C
body GMs throughout the 80's. Is it possible to buy only the power seat
switch, or is it sold with the power window switch included?

Thanks for all the help.
