Apparently no one has measured the actual current draw but they use the same 40 amp circuit breaker as the window motors. The circuit breaker is sized fairly large at 40 amps so if more than one window is operated at a time it will hold. The seat motors are constructed and wired the same way as the original window motors with the case getting ground and only one wire at a time getting power.

The only relay involved is the power relay operated by the ign switch. That relay is there to provide power to the windows and seat only when the key is in an on position. The seat motor should not be drawing any more current than the stock window motor. If I had to hazard a wild guess I would say maybe around 8-10 amps when seat is freely moving and maybe 15 under load and 20-25 when the motor is stalled. It might even be a bit less.
