Tow wiring accessories support your towing electrical connections with junction boxes, wire splitters, adapters, and protective gear. These components help you install, maintain, and expand trailer wiring systems beyond basic plug-and-play connections. Whether you're adding auxiliary circuits, troubleshooting wiring issues, or protecting connections from weather and road debris, the right accessories make the job easier.

What to Know Before You Buy

• Junction boxes provide clean connection points for multiple wire runs and make troubleshooting easier.
• Wire splitters (circuit testers) help diagnose which circuits are functioning when lights aren't working.
• Heat shrink connectors and dielectric grease improve long-term reliability of electrical connections.
• Wiring looms and conduit protect exposed wires from abrasion and UV damage.
