12/7 Trailer Cable

TC127-C

$289.46

| /

7-conductor trailer cable with six 12 AWG conductors and one 10 AWG white conductor (commonly used as the ground) in a flexible, oil- and abrasion-resistant PVC jacket. Made to SAE J1127/J378; rated -40°F to 185°F.

Use it for: wiring 7-way RV-blade plugs on heavier trailers — running, brake, and turn lights, electric brakes, 12V auxiliary power and reverse.

Choose something else if: the trailer only needs lighting circuits — our 16/6 trailer cable is lighter and less expensive. See our guides for electric brake wiring, and all trailer cable.

Available in 25ft and 100ft lengths.
