Voltage reducer connected through ignition switch for Radio

[jalthaus5tx]

I have 2012 EZGO TXT with 6 8V batteries. I purchased a 48 to 12 voltage reducer to be able to connect a 12V bluetooth speaker/charging accessory. I only want the radio to have power when the switch is on.
The standard wiring for the voltage reducer would be:
48V point to red input on Voltage Reducer
Ground from battery to black input on Voltage Reducer
Then accessory to the Voltage Reducer output wires.

How would I wire through the ignition switch to prevent the radio from playing when switch is off?

I'm sure I could buy a switch to put between the VR & accessory, but I have others that drive my cart and don't want them to forget to flip the switch.

This is the Voltage Reducer: EPBOWPT 120W Voltage Regulator Buck Converter 48V to 12V 10A Waterproof Voltage Reducer for Golf Cart.

Your help is greatly appreciated.

Thank you Spartan Mark. I looked over them. My Voltage reducer doesn't have a specific wire to go to the Key Switch. Based on what I'm reading, I just run the input positive from the VR to the Key Switch green wire. Thank again for the quick response.
