Wago Connectors

Eliminate electrical failures and drastically speed up complex upfits with WAGO 221 Series LEVER-NUTS®. Traditional twist-on wire nuts and cheap crimp connectors are notorious for failing under the intense vibration of a patrol vehicle, leading to dead lightbars and massive diagnostic headaches. The WAGO 221 completely modernizes fleet wiring. Utilizing patented CAGE CLAMP® technology, these compact, tool-free connectors lock down solid and stranded wires with absolute security. Rated for up to 32A and visually verifiable through a transparent housing, they are the mandatory standard for professional 12V emergency vehicle upfitting.

Key Features & Upfitter Specs

Vibration-Proof CAGE CLAMP®: The spring-loaded lever mechanism exerts continuous, precise pressure on the conductor, guaranteeing the splice will never vibrate loose during high-speed off-road pursuits.
Tool-Free Installation: Drastically reduces labor time. Technicians simply strip the wire to 11mm, open the orange lever, insert the conductor, and snap it closed—no crimping tools or heat guns required.
Transparent Housing: The clear polycarbonate shell allows installers to visually confirm that the wire is stripped to the correct length and fully seated against the back of the terminal block.
Universal Gauge Compatibility: A single connector seamlessly accepts any combination of solid, stranded, or fine-stranded copper wire ranging from 24 AWG up to 12 AWG.
Integrated Test Ports: Features a built-in testing slot at the front and rear of the connector, allowing technicians to verify voltage and continuity without ever removing the wire.
