Power Seat Wiring 97 Chevy Sub

I am installing power bucket seats originating from a 97 Chevy Suburban into my 39 Chevy Street Rod.  The seats have 5 wires going to a harness plastic socket..  I an trying to figure out how to wire these up to my car.  the controls are on the side of each seat.  I do not know if the 2 seats need to be wired together or alone.  what the wiring color code is, etc.  If anyone has a diagram or can shed some light it would be appreciated.

On some power seats I've wired for some of my street rod customer's I normally don't have a wiring diagram and they usually don't know exactly what they came out of so what I do is trace the wires down to see what wires go to the switches on the side of the seat, which wires go to the motors, and what wires might go to seat back interlocks, position sensors, or seat heaters and lay it out on paper and figure it out. I have seen some seats to where the switches on the side of the seat are low amperage and you have to add relays to them before conecting them to the seats motors.

Normally I would think a basic power seat would have two wires out of the seat base. One to power (ignition or battery) and the other to ground. The power seats I have done the motors have two wires on each one and by applying 12 volts to one wire and ground to the other the motor runs one way and moves the seat one way. By reversing the wires to the motor the motor spins the other way and the seat nmoves the opposite way. I would not try jumpering to the motors with a 12 volt source and ground as the switch on the side of the seat may have all wires resting on ground but I think if you trace things down or use a meter you should be able to figure out what wire is doing what. If all else fails, go to a dealer and see if they can print out a diagram or troubleshooting/diagnostic info. This should call out what wire does what or what wire should have power or ground at a particular time.

When you get them wired you may want to add an inline automatically resetting breaker on each seat. Fuses are OK but if you hold the seat switch in one position too long (like having it all the way forward and it stops but you still have the switch activated) it will blow a fuse and then it has to be replaced while an auto reste breaker will trip open and then try to reset. If the fault is gone the seat will work again. I've also connected the ground for the seats to the mounting bolt and only have to run a power wire from each one to the fuse block.
