I have successfully installed ERR TMCC electronics in Lionel engines containing conventional Pullmor motors. At this point, I have two MTH ProtoSound 1.0 Premier F3 A-B-A sets that I would like to equip with Electric RR Cruise Commanders. The F3 sets are: Burlington 20-2085-1 and Lehigh Valley 20-2086-1. MTH delivered both sets in 1996.
However, I don’t know to connect the existing grain of wheat bulbs already present in the F3 cabs and headlights into a Cruise Commander board. As far as I can tell, the relevant ERR manual does not provide information on how to connect existing bulbs, however.
Does anyone have a solution or a schematic to solve this wiring problem? Thanks
