Description

Overview

The Tow Ready 118702 is a 7-way flat pin to 4-way flat trailer light adapter. It plugs into the factory harness and provides a pigtail that the trailer lights plug into.

Key features

  • 7-way flat pin input
  • 4-way flat output through a pigtail for trailer lights
  • Plugs into the factory harness
  • It is universal fit.

Using a trailer light adapter

A 7-way to 4-way adapter lets a tow vehicle with a 7-way factory plug power a trailer that only uses a 4-way connector. The adapter sits between the two plugs, so the trailer’s lights, and the pigtail that carries them, are fed from the vehicle’s wiring without any splicing on the trailer side.

Before buying, match the adapter to both ends of the setup. The vehicle side needs a compatible factory plug, and the trailer side needs the pigtail to reach the light wiring. A loose connection at either end can cause flickering or dead lights, so plug the adapter in firmly and recheck it after the first stops.

  • Confirm which plug your tow vehicle has before buying
  • Keep the pigtail routed away from the hitch
  • Test each light function before towing

Questions & Answers

Is the Tow Ready 118702 a 7-way to 4-way adapter?

Yes. It is a 7-way flat pin to 4-way flat adapter with a pigtail that the trailer lights plug into. It plugs into the factory harness on the input side.

What is the Tow Ready 118702 part number and UPC?

The part number is 118702 and the UPC is 1611806651. Tow Ready makes it, and it is a trailer wire adapter for trailer lighting, with universal fit.

Will it work with my vehicle's factory harness?

Yes, it plugs into the factory harness, but no vehicle models are named. Check your tow vehicle's connector before ordering, since fit depends on that harness.

What is the difference between 4-way and 7-way connectors?

A 4-way flat connector carries the basic trailer lights, while a 7-way connector adds circuits such as electric brakes and auxiliary power. An adapter only converts the plug shape, so the trailer's needs still decide which connector is required.

How do I test an adapter after installing it?

Connect the trailer, then check each light function, including running, left and right turn, and brake lights. Confirm every signal works before towing, and recheck the connections after the first short drive.
