No that's the right way round. Not sure if the monitor cable was for this cab originally came in a box of wires not connected. Would the monitor usually be connected straight to the PSU. Thanks.
Okay onto the next problem the AC coming into the cab is incomplete and I'm not sure what's missing. Photos bellow. The first picture is the power cable coming from the monitor I have no where for this to go. The second is the power coming into the cab ends at this connector.
