i have a 1990 LS and i wanted to replace the front seats because the motors had gone bad in both front ones. so i got a pair from the junkyard but the driver side doesn't work. i believe i has the memory unit on it. there are like 12 wires on the harness and the original seat only has 3 wires. the colors on the pins and wires match up to the harnesses. i plug the seat in and there is no response. is there a way i can bypass the memory on this? thanks for your time.
