Yes Taft are very lean on anything regarding info.....

Even the CG for God's sake!
Looking at your connector pins suggests a dedicated board with male pin sockets.
The unit usually used in these sort of planes are a just a small shrink wrapped board and some lead outs with micro connectors. Runs off the BEC. If it just landing lights then all you need is one of these

plug it into the desired channel and away you go.
Without actually seeing the set up then difficult to suggest what you need.
Try a 1.5 volt cell to power one led and see if it lights up sufficiently first. If it does then possibly a 220 ohm resistor will drop the BEC volts down for you. On the other hand the Leds may have inbuilt resistors so they can be powered directly from the BEC.
Are you sure there is nothing in Fuselage laying around somewhere?
