Review on Automotive Battery Quick Disconnect Pigtail Wire Harness with Dust Cap - SAE Connector DC Power Extension Cable (16 AWG), 6 Pcs, 1.2 Foot Length by Noe Miceli

Good product. Exactly as described and photographed in the ad. Some reviews say "wrong polarity", I believe this is buyer's mistake. This connector has the red wire going to the pin and the black wire going to the output, so this is the correct connector to connect a load or charger. If you use a pigtail on the battery side, you will need to buy another connector with a red connector. Load side contact, battery side socket for red positive. I use them on motorcycles and my RV for wires coming from the charger or a voltmeter to check battery voltage.
