Please keep us informed as to your efforts, and results; your success could be a big help to others trying to use later model seats in their street rods. As you know, more, & more vehicles are using multiplexed wiring architecture for their accessories to simplify wiring, keeping costs & weight down. To adapt the newer hardware to our older rods will continue to tax our creativity.......

I'm not clear on your drawing...... Your drawing indicates each micro switch controls two movements or 8 actions. What are the other actions? How many motors are they controlling?

Grn & Pnk = FWD
Grn & Blk = BACK
Red & Blk = DOWN
Red & Pnk = UP
Yel & Pnk =
Yel & Blk =
Blu & Blk =
Blu & Pnk =

Here's what I came up with for the fwd/back seat motor. I assumed the Blk wire was the ground and was hooked to the normally closed terminal on the switch. You need to unhook the NC terminal on the switch, you only need the NO portion of the switch to energize the relays. The relays will reverse the polarity to the motor just like the original switch etc......

One of the low trim level versions of he CTS came with Non memory drivers seat.The harness was wired with the heavier switches to hook to battery voltage. Switches were heavier to accommodate the current rating. Also the switches would interchange in the seat .
I would shop for a wreck with the non memory harness.
Maybe LKQ or a U pullit yard? Just sayin

Solved

EOD Guy, thanks for your help. I didn't see your post till this morning. I figured thing out yesterday. So, what I have is 4 motors (2 positions per motor) 8 positions. The problem that I had was the 2 wires that were common to all 4 switches because when I hooked them up to the relays the switches were not independent and would cause all motors to go at the same time regardless of what position I selected. If I was running 12v power through the switch lets say to the 4 colored wires (green, blue, red, and yellow) then when I activated the switch, it would send the power out the pink and activate the 4 up/forward relays. Vise versa for the down/back position. If I tried to run the switches as a ground circuit, the same thing happened. I just didn't have enough wires coming out of the switch panel.
Here is how I solved it. I took the switch panel apart (see attache photos) and found the pink and the black mapping on the circuit board, Then I used a small dremel tool to cut the mapped circuit and separate each switch. Then I left myself enough space next to the switches to clean a new spot off so I could solder on/connect a black and a pink wire to each switch. This would give me the 2 wires per switch that I needed to complete the circuits independently. After I soldered it all up, I added some liquid electrical tape to each contact, zip tied all the wires and put the switch control back together. In the end, I used the switches to complete the ground circuit for the relays.

Very clever problem resolution! How many relays are you using in this configuration?

Crdnblu - I used 8 relay in this setup. It requires 2 relays per motor, 1 for forward/up and 1 for back/down. Here are a few pis of the finished project.

Are the memory switches functional? I could see where they could be re-purposed for Automotive things.....like power window and power lock switches.

I drew it up for you, I think this is how you have it wired...... terminals on the relay, 85 and 86 are interchangeable (each are one side of the coil)

WOW, EOD GUY!!!!!!! That is really cool that you drew that up for me!!! Thank you very much! Now I can add that to my little book of wiring know how instead of all my little drawings... I'm beside myself that you took the time to do that!

Yes, I think a person could very well hook those other 4 little micro switches and use them to run other things. They were all just momentary on switches.

Thanks again! BTW, what program do you use to do that?

I used power point, then saved as a jpeg. It only took about 20 min.
