4 Installation of the LE1835E
These decoders come with a NEM652 / NMRA RP-9.1.1 medium plug.This plug makes installation
of these decoders very simple.
To install the decoder simply remove the dummy socket in your locomotive and install the decoder
plug. To ensure the headlights work properly you must align the plug properly. Pin 1 of the plug
connects to the orange wire. Ensure this is aligned to pin one of the locomotive. If the plug is
installed backwards the lights will not work.
Be careful when installing the plug so that the pins will not be bent or broken.
