Here are some pics of the wiring, there seems to be a burnt out piece that once has wires connected but this may have been re-routed. There are two wires not connected and seem wrapped with the bunch they are blue and possibly go into the connector that has other blue wires in it. Really not sure. This may look a mess to most. When I turned it on the sound was really loud does anyone know how to adjust volume. Any input appreciated. Regards Paul
