Default 12ways seats wiring scheme

Hi everybody,
I'm bart and altho I dont own bonneville I do need help with wiring of the 12ways seats from bonneville. Basicaly I've got seats, rails, control unit and damaged wiring harnes. Now I've got all the inflating functions working and nothing else which is clearly since part of the wiring harnes is gone. Here is what I've got: Control unit has 3 connectors, two 10pin ones (blue and white) and one 8pin, out of all of these I only have connection to white 10pin and 8pin. So the 10pin white connection goes to the pass side while 8pin goes to driver side. Now my question is, what are the functions of each cable in the 10pin blue connector and what is the function of each cable in the pass and driver 2pin and 4pin conector (one pin on the 4pin connector is empty so each seat has 5 cables comming out of it). Also how should I connect that 10pin connector to the five cables that come of the seat (in my case its yellow and dark green from 2pin connector and green/white stripe, light green and brown from the 4 pin connector.

Sorry for this poorly written question but its really late here and I'm about to go nuts if I dont figure this out.

Yeah these seats do have inflatable lumbar support and as to what year it came out of, well I have no idea, but my educated guess would be 95-97. Again Im not too sure about the year tho.

OK, the control unit should have a black connector, a blue connector, and a white connector. The white one (5 wires) goes to the passenger seat, and the black one (5 wires) goes to the driver'* seat. The blue one (10 wires) goes to the switches (for the bitches).

The black wire from each SEAT goes to a ground. There should be a black wire on the control unit which also goes to ground. There should also be a black wire on the switches that goes to ground.

Basicly I've got 5 wires hangin off each seat and I've got blue 10pin connector hangin uselessly off the control unit.Everything else is connected and working properly.

The switches are the switches! You know, where you push the buttons for the seat controls.

I bet you do not have the control box with the relays in it.

what I have is obviously the seats, control unit (9 button one) and partial wiring (all Im missing is the part that goes from controls blue connector to the seats). I figure it goes to the seats since the connector is 10 cables, and I've got 5 cables coming from each seat despretly waiting to be connected to something. Anyway if you guys could just tell me how to connect that blue 10 pin to the seats, all Im looking for is which cable goes where when it comes to the 10 pin blue connector. If not that then could you please tell me where to get new wiring harnes and how much doe would it cost?

Thx

Unfortunately the 10-pin blue connector does not go to the seats. Read my above posts again. It goes to the control box with relays in it, which I'm betting you don't have. The control box is not the unit with the switches.
