K4-LK Light Board
The K4-LK is a function-only lighting expansion board which has been designed to be installed into the KATO N-scale MP36PH.
This board has three hookup wires - One RED Anode(+) wire (center) and two GREEN function wires(-). Simply solder the wires to the decoder as described below and your lighting kit will be ready to operate. (Also see the wiring diagram on the "Documents" tab) The K4-LK supplies light to the rear headlight as well as the rotary beacon on top.
NOTE: The K4-LK is not a decoder and does not offer any functionality by itself. The K4-LK is designed to be used with its parent decoder - the K4D6.
