I know that shine you make is pretty deadly but we're talkin's about battery juice. We carry a full line of MK chargers. We can also help you with the installation and wiring instructions. We've installed hundreds of battery chargers. You STREET RODDERS AND ANTIQUE CAR NUTS should install a single bank charger inyour cars. I put one in my Street Rod and wow is it convenient!
