I recently replaced my factory stereo in my 95 legacy Outback with an aftermarket one, a JVC. I had to spend some time figuring out the wiring but to little avail. The stereo works, sounds good however this is where the problems begin. Can't find the memory power supply so the clock and my presets are reset every time the car is turned off. Also, and here is my real problem, somehow I have managed to get my dash illumination to work only when my headlights are off. I have found I only need two of the four extra wires originally connected to the factory beast, to get power locks, lights and illumination to work. I discovered this through trial and error and blew a couple fuses in the process. my dimmer switch seems to not be working now. Is this likely the problem? and if so how hard and expensive is it to replace such switch?
