I'm looking to install a keyless entry system on a 1993 Audi 90 with an existing keyless entry system that isn't working. I assume all of the stock hardware, i.e., door lock actuators, etc, will be sufficient. Does anyone know where I could find the factory wiring diagrams for this installation or have any ideas as to the best way to go about this? Thanks.
