Connect 12-volt accessories, like a fish finder, livewell pump or navigation light into an integrated Yak-Power system on your kayak using the Power Plug SAE Connector with 4 Wire Pigtail for plug-and-use convenience. Use it to plug 12-volt accessories directly into the following Yak-Power products (sold separately): Power Ports (YP-PMC48S, YP-PMC96S, or YP-PMC144S), Power Panel switching system (YP-RP5R), Power Pack battery box (YP-BBK), and Battery Terminal pigtails (YP-BTP12 or YP-BTP96). Simply connect the accessorys positive (+) wire to the red wire on the Power Plug and the accessorys ground (-) to the black wire. Includes SAE plug with 4 wire pigtail, two butt connectors and two pieces of heat-shrink tubing for a secure, weather-resistant connection. Warning: All Yak-Power plug-and-play accessories are specifically designed to work together while maintaining the correct battery polarity throughout the entire Yak-Power system. Use of other aftermarket connectors or splicing other connectors into the Yak-Power system may cause damage to the system or to the accessories connected to the system and void your warranty. Caution: Always pay attention to the actual wire colors of all Yak-Power accessory cables to ensure that the RED(+) wire is always connecting to the RED(+)wire on the connector into which it is being plugged.
