My car is a Toyota Corolla S 2011 I recently changed the factory radio unit with a aftermarket unit that has steering wheel control compatibility. Her is the problem the plug for the steering wheel control that came with the new radio is 20 pin plug and the one that my car has is a 28 pin plug. So I need the radio wiring schematics whit the color combination of my car so I can connect the radio steering wheel control cables of the new radio directly to the interface of my car all I need from the 28 pin plug of my car are 3 cables but I need those schematics so I can know witch are the cables I need to connect and combine.
have the same problem?
