Tips

Use a ratcheting crimp tool designed for insulated terminals to achieve a gas-tight connection. Strip the wire to the correct length (typically 6-8 mm) and ensure no stray strands protrude from the barrel. For marine or outdoor use, apply adhesive-lined heat shrink over the connection for extra moisture protection.
