I'm looking to install a 12v power outlet on the dash of my RXV. This is a 4 X 12v battery cart. Does anyone know if there is a spare set of +/- leads at the dash that i can tap into. 

I know I can place one adjacent to the charging port of the cart but would prefer on the dash. Also don't know if the power going into the dash is 48v or has gone through a power reducer to bring it back to 12v. 

Lastly I'd prefer not to run new wires from the bank to the dash.
