Self-clamping electrical T-connectors connect to any wire without the need for cutting, stripping or soldering. The insulated connectors are made of durable brass and PVC. Nylon connectors are designed to fit snugly over the T-Tap connectors to prevent them from falling out. The plastic housing does not open once snapped onto the wire. This is a very convenient and practical solution for your vehicle. This kit gives the driver the ability to quickly connect any cable in any application.
