I have a Bachmann Texas & Pacific 4-6-0 HO scale locomotive. I'm in the process of adding a sound decoder. I'm looking for the wires for the headlight (white and blue). the wires in the tender are all black. Would the terminals labeled L+ and L- be for the blue and white wires respectively? I'm assuming M+ and M- is for the motor.

L+ and L- should match up to Pins 7 and 6 on the NMRA 8 pin plug on the circuit board. But I always double check with an ohmmeter. Just out of curiosity way are you not just using the NMRA 8 pin plug? (I have not installed a decoder into 4-6-0 yet.)
