Bachmann Plug and Play

[snowshoe]

Im hooking up a RCS Rx65b to the Forney plug and play.  Im using the the provided board to wire an aftermarket rc.  I got as far as getting the engine to run forward and reverse but I can not get the front lights to work.  I have the white wire from the bachmann board going to the correct wire on the Rx65B but Im not sure what other wire I need to finish the connection?  Is the Bachmann board front light wire + or-.  If I want to hook the cab light what wire should I use. Please see this for more info.
