Buying Guide

Choose the right conductor count

Match the wire's conductor count (4, 5, 6, or 7) to your trailer's electrical functions like lights, brakes, and auxiliary circuits

Prefer 14 AWG for most trailers

14-gauge wiring is the standard used across these picks and provides suitable current capacity for lighting and small brake circuits

Check conductor material

Copper conductors offer better conductivity and corrosion resistance than CCA alternatives; select copper when longevity matters

Pick length for routing and spares

Choose a cable length that covers your vehicle-to-trailer route with extra slack for connectors, bends, and future repairs

Verify color coding and labeling

Clear color codes (red, blue, green, white, yellow, brown) simplify installation and troubleshooting on multi-wire harnesses
