I am doing work inside car (new speakers, JDM folding mirrors, evaporator cleaning, etc.) and thought that while the door panels are off why not install auto up/down window modules. The previous owner butchered the radio wiring so I do not feel too bad about cutting into the cars OEM wire harness. Can anyone recommend what to use? I am sure aftermarket units do not exist and that the circuit that does this form another car will be necessary.
