You should have 2 wires for 12~15 power going in, which you already indentified, 2 more wires should be for ground return, you can check for them by using Ohm meter between the chassis and probe the wire for less then one Ohm resistance. The other two wires, 1 wire will be for Dimming control (usually 0 = dimmed, 5vdc = full brightness), 1 wire will be for BACKLIGHT ON/OFF (0v= OFF, 4~5VDC = ON) control.
Dose the fuse on the inverter board check out OK? You can use other inveter board as long as the lamp connectors are the same and you just have to match the input signal pin. I have done many.
See example of the fuse on the inverter board.
