I've done some more research and wonder if one you guys would render an opinion. I've found a PWC FM with a different type of ERU. Product link: https://www.lionelsupport.com/...b5-9f08-a359193a3030
Once there, please look at part sequence number 4.
Do one of you guys think this will work?
Thanks,
Steve
ps: I was able to find the wiring diagram for an FM using this board. It is in supplement 45. It cleared up some questions.
