Dan asks readers:

“I have the Kato ho scale Metra can car and I have wired up the two pickup wires, and the speaker wires. I can get the decoder to turn on and off, but no sound effects and I am wondering how I wire the lights up to the existing light control board or do I have to buy new LEDs and wire them separately and remove the factory control board? I really need the help! I am a newbie to HO dcc.”

Be sure that your ground wire from any light is feeding to the common wire (ground) of your decoder.
whether regular bulbs or LED’s and you may need to program the decoder for the function of the light you will want to work. If hooking up LED’s then make sure the one side of the LED is hooked up to the positive side of your wiring. If they are reversed they will not work Newman

Can you add a circuit diagram to your post, so that we can understand the problem and see what you have connected to ?
