Does anyone know how/where to get power to your trailer to charger the batteries. I have installed the wire to the power distrubution box in the engine compartment

If you hook up the wires under the hood, you''ll have 12 volts to the connector.
Send me your email address and I''ll send you instructions for doing it. dyjack@aol.com

I have hooked the wire under the hood to the power distrubution box. I was told there is a dummy fuse is the box.
