I need the wiring diagram for the stock HU Non-Nav TSX 04. My problem is I've replaced the PCB board because all the lights went out on the center console and HVAC. It fixed the display problem on the stereo display and AC uint, but the buttons are not lighting up. I may have spliced a wire behind the stock HU and am wondering what color is the wire for the button illumination. There is a possibility the PCB is faulty, but the lcd display works for the stock unit and AC temperature reading. I don't know what the problem is. Can someone point out the wiring diagram on the back of the HU. It would be very helpful. Thanks
