Fastway ZIP Breakaway Cables: Switch, Pin & Length Guide

Replacing a trailer breakaway cable is easier when you know which parts of the existing system need attention. The Fastway ZIP family includes a complete switch-and-cable assembly, a cable supplied with a new pull pin, and a universal cable that connects to your existing switch pin. Each is offered in a 4-foot or 6-foot configuration; these are six separate manufacturer part numbers, not interchangeable package names.

Which Fastway ZIP configuration do you need?

Switch and cableChoose 80-00-2040 (4 ft) or 80-00-2060 (6 ft) when replacing the breakaway switch housing along with the coiled cable. A working trailer breakaway battery and brake wiring are still required.
Cable and pull pinChoose 80-01-2204 (4 ft) or 80-01-2206 (6 ft) if your switch housing remains serviceable but its pull pin or cable needs replacement. Match the pin style to the existing switch.
Universal cable onlyChoose 80-01-2140 (4 ft) or 80-01-2160 (6 ft) to keep your existing compatible switch pin. A split ring attaches the replacement cable to that pin; the pin itself is not supplied.

4-foot or 6-foot cable?

Fastway recommends a 4-foot ZIP cable when the distance from the breakaway switch to the tow-vehicle connection is less than 3 feet. For a distance greater than 3 feet, the manufacturer recommends 6 feet. The shorter version commonly suits bumper-pull trailers; the longer version is often suitable for gooseneck and fifth-wheel arrangements. Measure your actual connection route rather than selecting solely by trailer style.

Leave enough extension for normal turning without pulling the switch pin, but not so much loose cable that it drags, catches or becomes tangled. The coiled, coated design helps keep the cable up and out of the way during towing.

The breakaway cable is not a safety chain. Its job is to pull the switch pin if the trailer separates from the tow vehicle, activating the trailer's independent emergency-braking circuit. It does not carry trailer weight or replace correctly rated safety chains. A new cable alone will not repair a failed breakaway battery or wiring fault.

What to check before ordering

  1. Find the existing assembly type. If the switch or electrical leads are damaged, evaluate a complete switch replacement rather than a cable-only part.
  2. Confirm the switch pin. The Fastway pin supplied with the cable-and-pin models works with ZIP switches and many similarly styled breakaway switches. Do not assume that every switch accepts the same pin.
  3. Check the attachment path. Measure from the mounted switch to the designated tow-vehicle connection at normal towing position.
  4. Test the system correctly. Follow the trailer and breakaway-system instructions to verify the battery, electrical wiring and emergency brake application before towing.
