Items used:
ESU 58429 LokSound 5 DCC 21-MTC decoder
DCCSound Premium sugarcube speaker to suit Auscision C44 (1st run)
To access the 21 pin plug, the body is removed from the chassis.
Remove the coupler assemblies then the four small screws in each corner of the chassis. Set these small parts aside in a safe place.
Next, gently lift the body off from the chassis. Take care as two sets of wires from the body join in to the motherboard.
Next, remove the rear enclosure via two small screws securing it to the metal chassis. Use these two screws to mount the DCCSound premium speaker to the chassis.
Once fitted, plug the decoder in, noting its orientation.
Gently refit the body to the chassis and refit the prior removed couplers and 4 body attachment screws.
