Maxtrac accessory plug pinout

Post by firedog359 »

Hello all, I have a Maxtrac set up as a base.It's being powered by a Motorola A/C power supply.Iwant to power the tone termination panel using the accessory plug on the Maxtrac.I know that pin 13 is the +12 volt supply from the on/off switch but I'm not sure which pin to use for the negative/ground. Any help would be greatly appreciated.Thanks
