Note, the power window wiring harness is installed by fisher body. It plugs into the main dash harness installed by Chevy. This is why the power window option is coded onto the cowl tag. The chevy wiring diagrams for optional equipment will only show the lead to the harness.
Component Description
Power window regulators are different than standard window regulators. The window regulator
needs to accomodate the motor. When power windows were installed in a car the place where
the manual window crank would normally be installed was covered by a round medallion.
