Updated: Jun 7

Items used:

ESU 58429 LokSound 5 DCC 21-MTC decoder

DCCSound Premium sugarcube speaker to suit RMM GT46AC

To access the 21 pin plug, the body assembly is removed from the chassis.

First, remove four flat-head fine threaded screws from under the chassis, in each corner of the chassis. Also remove both coupler assemblies.

Disconnect the hose on the driver's side near the step, then gently lift the body off from the chassis.

Next, remove the 21 pin DC socket/PCB from the 21 pin plug, along with the sound enclosure.

Next, fit the DCCSound premium speaker to the chassis, applying a small drop of adhesive to fix the underside of the speaker to the chassis.

Secure any loose wires, then refit the body assembly to the chassis, refitting screws and couplers.
