Pos Ground 6 Volt to Neg Ground 12 Volt

Here is the plan to get the M radio to work on 12 volt negative ground system. Normally the M radio is not polarity sensitive but the vibrator I'm using is. Good thing that a positive and a negative ground vibrators are made... I also (in a previous post) decided to use a bridge rectifier for the LED dial lights so there would not be a polarity issue with them.
