Deutsch Switch Harness

This pre-wired Deutsch-style harness provides a secure, plug-and-play connection between switches and load circuits. It’s ideal for marine, off-road, and industrial setups where vibration, moisture, and corrosion are concerns.

Built around the trusted Deutsch-style connector system, this waterproof wiring harness delivers a sealed, weather-resistant connection that holds up in tough conditions. It simplifies wiring, reduces install time, and ensures consistent, professional results.

Choose the 4-wire version for single output, with a dummy plug sealing the unused port, or the 5-wire version for dual outputs. Both are pre-wired to eliminate guesswork — no crimping or assembly needed.

This Deutsch waterproof wiring harness is built to last in high-vibration environments and offers a clean way to route power from switch to load without clutter.

Each harness is made to order, with cut-to-length customization available. Just contact us with your specs and we’ll build exactly what you need.
