Nylon Connectors

Our nylon connectors help installers join, terminate, or disconnect automotive wiring with an insulated connection. They suit audio upgrades, repairs, and accessory wiring where a reliable wire-to-wire or wire-to-terminal joint matters.

Match Connector Gauge to the Wire

Start with conductor gauge, then choose the connector shape for the job. The product colors here correspond to distinct wire ranges: yellow covers 12–10 AWG, blue covers 16–14 AWG, and red covers 22–18 AWG. Check the wire size and connector range together so the crimp grips the conductor securely. For a stud connection, the Install Bay YNRT14 yellow ring terminal fits 12–10 AWG wire and a 1/4-inch stud. The BVFD250 blue female disconnect takes 16–14 AWG wire and a .250-inch blade.

Choose the Connection Style for the Repair

Ring terminals fasten wire to a stud, while quick disconnects let you separate a connection without cutting the wire. Bullet connectors join wires through a mated male and female pair. The RNFB red female bullet connector is sized for 22–18 AWG wire. For a compact wire end, the CC2218 nylon crimp cap also suits 22–18 AWG. An instant tap connects a branch to an existing wire, but use the specified tap style and wire range for that connection.

Make a Secure Crimp

Strip only enough insulation to seat the conductor fully. Use a crimping tool made for insulated terminals, and pull-test the finished connection. A loose crimp can heat up or interrupt power. Keep exposed copper out of the joint, and route wiring away from sharp edges and moving parts. Insulation helps protect the connection from accidental contact, but do not treat it as a weather seal. Confirm the connector's electrical rating suits the circuit.

• Ring terminal: Match the stud opening to the fastener.
• Disconnect: Match blade width and terminal gender.
• Tap: Use the correct wire range and installation method.
• Crimp cap: Gather conductors neatly before crimping.
