I am trying to find where each wire goes on the 8 plug socket between the engine and tender on a 2-8-4 sound engine. Also the same on a 2-8-4 non sound 6 plug socket. Can the tenders be switched from one to the other. I prefer my NKP 717 be sound and my NKP 772 be non sound.
I would like to know whats involved putting sound into a non sound version that has the working mars light. Maybe we can figure this out together. Mike
