Model Trains 196 - Heljan Class 56 Real Time Sound Chip Install And Test Part 3. (And a correction)

Part 3
Welcome to fitting an ESU Loksound L V5 decoder to a Heljan class 56
Firstly a correction to the previous video.
I connected the roof fans to the fan terminals. This is actually for a smoke generator.
These wires need to be moved as per this video
I hope this video is of help and any questions or observations, please write below in the comments
