Tekonsha T-One ModuLite HD | 2017 Chrysler Pacifica
Tekonsha T-One ModuLite HD | 2017 Chrysler Pacifica — Product description
Adding a trailer, bike rack, or utility hauler behind your 2017 Chrysler Pacifica? The Tekonsha T-One plugs right into the factory taillight harness and adds a 4-way flat connector. The upgraded ModuLite HD module pulls trailer power from the battery and protects your van's wiring, so a blown trailer bulb never becomes your problem.
If you're towing a small trailer, a bike rack with lights, or a popup behind your 2017 Chrysler Pacifica, this is the wiring you want. The Tekonsha T-One Connector plugs straight into the factory harness behind your taillight, no cutting, no splicing, no test-light guesswork. It's the clean way to add a 4-way flat trailer connector to a vehicle that didn't come with one.
What sets this one apart is the upgraded ModuLite HD module. Instead of pulling trailer lighting current through your Pacifica's own wiring, the module draws power straight from the battery and uses the vehicle's light signals only as triggers. Your factory circuits stay isolated. That matters on a modern vehicle like the Pacifica, where the body control module doesn't love the extra load of trailer bulbs wired in directly.
The HD part is the circuit protection. If you short a trailer wire or a bulb fails in a way that spikes current, the module takes the hit instead of your van's electronics. It's self-resetting, so a momentary fault doesn't leave you roadside pulling fuses.
Installation is about as friendly as trailer wiring gets. You locate the factory connectors behind the driver and passenger tail lamps, unplug them, plug the T-One in between, and mount the module and the 4-way flat where you can reach it. Most folks have it done in under an hour with basic hand tools. No wiring diagram, no crimping.
One thing to know: this harness is built specifically for the 2017 Chrysler Pacifica. It's not a universal kit you trim to fit. If you've got a different year or a different vehicle, check with us first so we match you to the right T-One. And if you're not sure whether your Pacifica already has a tow package, we can help you sort that out before you order.

Frequently asked questions
Will this fit my vehicle?
It's built specifically for the 2017 Chrysler Pacifica and plugs into that van's factory taillight connectors. If you have a different year or model, check with us first so we match you to the right T-One harness.
Do I need to cut any factory wires?
No. The T-One is a plug-in harness. You unplug the factory connector behind each tail lamp and plug the T-One in between. No cutting, no splicing, no crimping.
What's the difference between this and a basic T-connector?
The upgraded ModuLite HD module. A basic connector borrows current from your vehicle's own light circuits. This one draws trailer lighting power straight from the battery and uses your signals only as triggers, so your factory wiring stays isolated and protected.
Does the 4-way flat provide constant power to a trailer?
It powers the trailer's running, brake, and turn lights through the module, triggered by your van's signals. It's a lighting connector, not a charge line, so it doesn't feed constant 12V to a trailer battery.
Where does the harness connect?
Behind the driver and passenger tail lamps. You reach the factory connectors, plug the T-One in line, then mount the module and the 4-way flat plug where you can get to it from the hitch.
What does the circuit protection actually do?
If a trailer bulb fails or a wire shorts, the ModuLite HD module absorbs the fault instead of your van's electronics. It's self-resetting, so once the problem clears, the module comes back on its own.
