Buying Guide

Choose the right conductor count

Use 7-conductor cable when you need separate circuits for running, brake, reverse, auxiliary power, and ground on flatbed tow setups

Match wire gauge to load

14-gauge copper conductors are common for trailer lighting and short runs; confirm gauge is appropriate for your lighting and brake controller loads

Select proper cable length

Measure route length on the truck and trailer and pick a length with extra slack to allow for movement and secure routing without tension

Prioritize corrosion resistance

Look for stranded copper conductors and durable jacket materials to resist road salt, moisture, and repeated flexing on tow trucks

Consider ease of installation

Pre-bundled color-coded seven-conductor cables speed wiring and reduce error compared with assembling multiple single wires
