Tekonsha 118494 4-Way Flat Wiring Harness Replacement
Tekonsha 118494 4-Way Flat Wiring Harness Replacement — Product description
The Tekonsha 118494 gives you a clean 4-way flat trailer connector that plugs straight into your vehicle's factory towing wiring. It's a direct replacement for the OEM harness, so there's no cutting, splicing, or guesswork. Cataloged for the 2010 Chevrolet Equinox, it gets your taillights and turn signals wired to the trailer in minutes.
The Tekonsha 118494 is a 4-way flat replacement for your vehicle's factory towing wiring harness. If you tow a small boat trailer, a utility trailer, or a lightweight cargo trailer, this is the connection that carries your running lights, turn signals, and brake lights back to the trailer. It plugs into the wiring your vehicle already has, so you get a clean, factory-style hookup without cutting into anything.
Here's what makes a plug-in harness like this worth it. A 4-way flat is the most common trailer connector out there. It handles four circuits: taillights, left turn and brake, right turn and brake, and a ground. That's everything a lighting-only trailer needs. No electric brakes, no reverse lights, no charge line, just the four wires that keep you legal and visible on the road.
This one is cataloged as a direct replacement for the OEM harness on the 2010 Chevrolet Equinox. That matters. Because it's matched to the vehicle, the connector snaps into the factory towing wiring instead of forcing you to splice, tap, or run a test light across a dozen wires. If you've ever fought a universal kit with butt connectors and a wiring diagram taped to your knee, you already know why a plug-and-play harness is the way to go.
Install is about as simple as trailer wiring gets. Find the factory connector, route the new harness to it, click it in, and run the 4-way flat back to your hitch area. Most folks have it done in well under an hour with basic hand tools. And because Tekonsha builds the connector to match the vehicle's plug, you're not guessing whether the turn signals will land on the right pins.
Keep in mind what a 4-way flat won't do. It's for lighting only. If your trailer runs electric brakes, you'll need a brake controller and a heavier connector like a 7-way. But for the huge number of single-axle boat and utility trailers that just need lights, this Tekonsha harness is exactly the right tool. Order with confidence using part number 118494 and UPC 016118044072.

Frequently asked questions
What vehicle does the Tekonsha 118494 fit?
It's cataloged as a direct replacement for the OEM towing wiring harness on the 2010 Chevrolet Equinox. Because it's matched to the vehicle, the connector plugs into the factory wiring instead of requiring you to splice into the harness.
What is a 4-way flat connector?
A 4-way flat is the most common trailer plug for lighting-only trailers. It carries four circuits: taillights, left turn and brake, right turn and brake, and a ground. That covers everything a trailer without electric brakes needs to stay lit and legal.
Do I have to cut or splice any wires to install it?
No. This is a direct replacement for the OEM harness, so it plugs into your vehicle's existing towing wiring. No cutting, no butt connectors, no test light. Most people have it wired up in under an hour with basic hand tools.
Will this connector run electric trailer brakes?
No. A 4-way flat handles lighting only: taillights, turn signals, brake lights, and ground. If your trailer has electric brakes you'll need a brake controller and a heavier connector such as a 7-way. For lighting-only trailers, the 4-way flat is all you need.
Is this the right harness for a small boat trailer?
If your boat or utility trailer uses a 4-way flat plug, yes. Most single-axle trailers without electric brakes use exactly this connector for their lights.
What are the part number and UPC?
This is Tekonsha part number 118494, UPC 016118044072. Order by those and you'll get the correct 4-way flat replacement harness.
