Switching out seats

My son has a '94 GT and recently purchased front (with tracks) and back seats out of a 2000 GT. Only problem he is having is with the drivers seat. The electrical plug on the '94 has two wires, a black and a lt. blue. The 2000 seat has a thin green, a thin purple, a thick green and a thick black going into the plug. Any suggestions on what he needs to do to make the seat work?

In case anyone wants to do the same, check here. 2001 seats to a fox body.

I was thinking about doing that switch to my 93 GT but those seats are too high for a tall person like myself
