Tekonsha 118534 T-One 4-Way Flat Harness, Grand Caravan
Tekonsha 118534 T-One 4-Way Flat Harness, Grand Caravan — Product description
The Tekonsha 118534 is a custom-fit T-One wiring harness built for the 2011 Dodge Grand Caravan. It plugs right into your van's existing wiring and gives you a standard 4-way flat trailer connector, so you can run your trailer's lights without cutting or splicing a single factory wire.
If you've got a 2011 Dodge Grand Caravan and you want to pull a small trailer, this is the wiring harness that makes it painless. The Tekonsha 118534 is a T-One custom-fit harness, which means it's shaped to match your van's factory wiring exactly. No guessing, no test-light fishing for the right wire. It connects to the existing harness and leaves you a clean 4-way flat plug at the back.
Here's what the 4-way flat gives you: running lights, left and right turn signals, and combined stop lights. That covers the basics for most small trailers. Think utility trailers, a small boat trailer, a teardrop camper, or a lighted bike rack. If your trailer runs on a standard 4-pin flat connector, you're set.
The big win with a T-One harness is the install. You plug it in. There's no cutting, no splicing, no scotch-locks biting into your factory wires. That matters for two reasons. First, it keeps the job reversible, so if you sell the van you can pull the harness and leave the wiring untouched. Second, a plug-in connection is just more reliable over time than a crimped tap that can corrode and drop a light circuit on you at the worst moment.
A word on what this harness is not. A 4-way flat doesn't carry a trailer brake signal or a 12-volt charge line. So if you're towing something with electric brakes or a trailer that needs to charge a battery, you'll want a 7-way setup and a brake controller instead. For light-duty towing on the Grand Caravan, though, the 118534 is the right, clean answer.
It's a Tekonsha part, so you're getting the same wiring know-how that goes into their brake controls and breakaway systems. Everything you need to make the connection comes in the box, and the plug ends are keyed so you can't hook them up backward. Route it, plug it in, secure the trailer-side plug where it won't drag, then hook up your trailer and go.

Frequently asked questions
What vehicle does the Tekonsha 118534 fit?
It's a custom-fit T-One harness for the 2011 Dodge Grand Caravan. It's shaped to match that van's factory wiring, so it isn't a universal harness.
What can I run off a 4-way flat connector?
A 4-way flat carries your trailer's running lights, left and right turn signals, and combined stop lights. That covers most small utility trailers, boat trailers, teardrop campers, and lighted bike racks.
Do I have to cut or splice any wires to install it?
No. The T-One design plugs into your van's existing wiring, so there's no cutting, splicing, or scotch-locks needed. That also keeps the install reversible.
Can I tow a trailer with electric brakes using this harness?
No. A 4-way flat doesn't carry a trailer brake signal or a 12-volt charge line. For electric brakes you'll need a 7-way connector and a brake controller instead.
Is this the connector on the vehicle or on the trailer?
This is the vehicle-side harness. It ties into your Grand Caravan and leaves a 4-way flat plug at the rear that your trailer's connector plugs into.
