Dual Power Cable Connector for high amp draw. I have started using these on my jeeps and trailers. I often find my self needing (may be its a want) a second battery, I have one hard wired in my XJ and up until that is where it has lived. So I started wiring the Doul Power connectors on the on the JK. So far I have added one the the front for jumper cables and my wench. and will be adding one for a portable second batter. the great thing about the connectors is they are color coded so only red will work with red ,yellow will work with yellow and so on. Making it easy to identify the purpose of the connector. for more information check out the video.
