320PCS Double Bullet Wire Connectors, 3.9mm 3.5mm Male Female Bullet Terminal Connector with Insulation Sleeve, Brass Crimp Terminal Wire Connector for Car Truck Motorcycle

You can get this on Amazon or any preferred store/site and get some wire as well to make either an extension or take the switch box open unsolder the old wire and resolder the new longer wire for a cleaner look. Personally I would get the connector set anyway it comes in handy just to have around since it has all ends and the insulation covers. https://a.co/d/07d1tBCH
