1940-1948 Chevy Front Doors-No Switches (Includes Motor Plugs & Terminals)

1940-1948 Chevy Front Door Power Window Kit with No Switches or Wire Harness
Kit includes: 2 regulators (left & right side), 2 new ACI motors, motor plugs and terminals for your wiring.

  • Note: Our ACI motors are reverse polarity motors and require reverse polarity switches. Reverse polarity means that the ground is within the wiring harness rather than off the motor. The easiest way to determine if you have reverse polarity switches is to look at the number of poles on the back of a single switch. You must have 5 or more poles to have a reverse polarity switch.
