The MC2 was added in by removing the four screws holding on the steel outer cover and then sliding off the cover.
The main PCB was connected at one and with a push on edge connector. This need to be gently removed. The MC2 was complete with its own edge connector which pushed onto the main PCB replacing the original wiring connector, The MC PCB was then fixed to the spare chassis brackets using an M3 nut, bolt and washers. The original connector was the fixed to the MC2 PCB to complete the installation. The wiring will be long enough to allow the connector to reach nearer to the rear to connect the new PCB.
