These allow SAE ends vs the alligator clip end. The SAE is a standard 2 pin that plugs into vehicles, RV's, and smaller campers with the SAE 2 pin. Please specify if you have the gray or red Anderson ends if buying for a solar kit you already have (drop down menu when adding to card). If you are buying a kit and want this connection just please send me an email after ordering and I will include it AT NO COST!
