I didn't see any evidence of cut wiring, but I really didn't look that close. It seemed to just be a 'plug in' type of operation. I'll try to look tonight when I have that car again. The part that you thought was a 'test switch': could this be the resistor that determines the fan speed? My original one was overheated and charred...
