On the 2002 protege radio, does anyone know what (wire/pin) is used for the radio back-lighting and to what wire on the RX-7 harness does it connect to? The lighting for the (clock/station) display works and so does the dimmer. I just can't get the backlighting to work. I am using an aftermarket harness for the radio.

See this link for reference.
