Connecting two wires to a DC 12v port on a controller board with 4 pads for a monitor
do a continuity test with one probe on a known GND pad and probe the unknown pads that show which 2 pads are GND do the same with the 12V line then just solder each wire to the right pad, there might be a reson for the 2 pads but if your just wanting to see everything powers on then there shouldnt be a problem
