Life Like GP-9 Chop Nose

I have the two CN models and have just installed TCS CN-GP decoders in them.
I have also done a little detailing by adding tube type spark arrestors a winterization hatch and a beacon over the cabs plus a side mount bell.
Only one more thing to figure out and that is to wire the two loco nose lights to the TCS decoders. Any suggestions?
 
Decoder Light problems

I had a friend wire the nose headlight into my Life Like GP9 chop nose but the it won't light. I have had email exchanges with TCS but they can't figure it out. This is ongoing. Has anyone else had this problem?
