I’m having fun working on a Lionel Bluetooth 2-8-0 Consolidation and I’m wondering about the connection from the 5 pin socket labeled “Switch” to the 2 switches for RS/TS and the Smoke on and off. I haven’t found a breakdown of which pins connect to the 2 switches. I can make up a plug but what goes where? Thanks for any help.

Turn the board over. The pins are labled on the back. Common is GND and don't ground the +5V. 
Thank you. I have the plastic bracket covering the back side of the card. So ground is on one side of the switches and the smoke or sound is on the other?
Right where they're labeled. All the switches return to ground. I don't really know what 5V is used for, I've never connected to it.
