Seriously I'd start by removing the old seats and see if the tracks match up, if they don't you'll have to fab some new mounts.

On the electrical forum you will sometimes receive an electrical response.
Well here goes.

As far as I can see these seats have (4) motors for the various positions. Maybe a 5th for lumbar but I'm not sure.
No matter how many motors each motor will have a forward and reverse direction.
The factory system is computer controlled by the vehicle system that is required to have all the features like memory including the feedback sensors to tell the computer that the memory position has been achieved.

To operate the seats without the computer the motors must be controlled directly using switches to connect them in either forward or reverse direction.
The attached diagram for the Caddy CTS shows the (4) motor/circuit breaker modules and associated wire colors for each motor. For example the "seat front vertical motor" uses D-grn and D-blu wire colors.
The seat position sensors will not be used. Some of the wires from the sensors are the same colors as the motor wires but are smaller sizes. You may need to test to determine which wires are for the motors by applying 12 volts to run the motor.

The second attached diagram shows these motors connected to a standard double pole double throw momentary switch. Each motor will need one of these switches.

Let us know how you make out.

I now understand what you are looking for, dispite the funny comment, do your seats have switches built into the seats? If not..... here is a simplified wire diagram for a single motor using automotive relays and simple push button momentary switches.... as mentioned above you will need one set per motor.

It appears that my second diagram did not attach.
I'll try again.

This is my best guess based off the wire diagram Vic supplied

16 pin black connector
D-Grn and D-Blu wires are for the seatís front or knee, up and down motor
L-Grn and Tan wires are for the seatís front to back motor
L-Blu and Yellow wires are for the seatís rear up and down motor

L-Blue and L-Green wires are for the seat back recline adjustment motor

You need to trace each motor wire from the motor to the switch, and figure out which wire coming from the switch needs power (there is probably only one wire that needs pwr) Iím guessing itís in a 2 wire black connector, one wire should be 12v and the other would be ground youíll have to make sure of this as I am guessing.

Example: If you put +12v on the D-Grn wire and ground the B-Blu wire the front of the seat will raise up. Then if you reverse the wiresÖ. + 12v on the B-Blu wire and ground the D-Grn wire the seat will move down.
