Important Usage Note

This kit will support all kinds of powered accessories, from fridges and lights to inverters and compressors. Be sure to check the total amp draw of your combined load before purchase and installation to confirm compatibility.

The power and ground wire are unterminated. This is so you can cut to length for your specific wire routing. Once you have determined the length, cut the wire, and trimmed the insulation, you can use the following tool to crimp the remaining lugs.
