How to Pay for a Trailer Brake Controller Setup

Mid-winter is the best time to buy towing hardware. Here is how to pick your harness and spread the $400 cost over 18 months.

VoAtlas editorial Updated · 3 min read
Typical cost $400 before anything else
Across the 0% window $22.22/mo 18 months, no interest

How we got that: $400 spread evenly across the 18-month introductory window on the Citi Simplicity® Credit Card. Checked · at the bank Carry a balance past the window and the standard APR applies to what is left.

Towing heavy loads adds real wear to your vehicle and hits your budget with extra fuel, maintenance, and gear. A reliable brake controller and heavy-duty harness usually run about $400, but mid-winter is when demand drops and prices soften on towing hardware.

When you are upgrading your rig, keep your choice of parts separate from how you pay for them. Using a promotional card window for the hardware lets you buy when prices are lowest without draining your cash reserve for truck maintenance.

Keep in mind that a 0% intro window is a repayment timeline, not free money. If you have a balance left after 18 months, interest applies to what remains, so set up an automatic payment for $22.22 each month right away.

The steps

  1. 01

    Time your purchase

    Shop for towing hardware in mid-winter. Retailers drop prices on controllers and heavy-duty harnesses during the off-season to clear out warehouse space before spring camping hits.

  2. 02

    Match your vehicle wiring

    Check under your dash to see if you have a factory tow plug. Getting a proportional controller with a custom harness for your specific make and model saves you from cutting and splicing wires.

  3. 03

    Use a 0% intro window

    Put the $400 purchase on a Citi Simplicity® Credit Card. You get 0% for 18 months on purchases and balance transfers from date of account opening, which comes out to $22.22 per month to clear the debt before the promo ends.

  4. 04

    Buy parts separate from labor

    If you are not doing the installation yourself, purchase the controller and harness online first. Shops often add a markup on hardware, so bring your own parts and pay strictly for the shop time.

  5. 05

    Calibrate before your first haul

    Mount the unit and adjust the gain on a quiet road at low speeds. Getting the power output dialed in at home prevents uneven brake wear and keeps your rig stable on the highway.

  6. 06

    Check the card terms before you commit

    Every figure we publish for the Citi Simplicity® Credit Card carries the date a person verified it against Citi and a link to where they checked. Intro windows and APRs change without notice, so confirm the current terms before applying.

Common questions

Is a proportional brake controller better than a time-delayed one?

Yes. Proportional controllers sense how hard your truck is slowing down and mirror that force on the trailer brakes, giving you smoother stops and less wear on your truck.

Can I install a brake controller and harness myself?

If your truck has a factory tow package, installation is usually a quick plug-and-play job under the dash. Without a factory plug, you will need to run power to the battery and wires to the rear bumper.

Why is mid-winter the best time to buy towing gear?

Towing activity drops sharply in cold months, so auto suppliers and online retailers discount hardware to move inventory during the slow season.

How much does a shop charge to install a brake harness?

Labor usually costs between $100 and $250. It stays on the lower end if your vehicle already has a factory connector under the dashboard.
