G-Major / G-Major 2 / G-System: Channel switching cable for Marshall TSL amp


How do I assemble a cable to make the G-Major / G-Major 2 / G-System's relay switching work for my Marshall TSL amp?


Please assemble a cable according to the attached PDF drawing which you can download here.
Please note that you will have to choose between either channel switching OR reverb/effects on/off, as the G-Major "only" has two relays.
