Product Details

The CURT 51520 is a trailer brake controller adapter harness designed to bridge the gap between competitor vehicle-specific wiring harnesses and CURT trailer brake controllers. If you already have a Tekonsha, Reese, Draw-Tite, or Pro Series plug-in harness installed in your vehicle, this adapter eliminates the need to replace your existing wiring — simply connect this adapter and plug in your CURT brake controller.

Key Features:

  • Allows CURT brake controllers to be used with competitor plug-in harnesses
  • Compatible with Tekonsha, Reese, Draw-Tite, and Pro Series vehicle-specific harnesses
  • Connects to any CURT brake controller (except the Echo model)
  • Features two plugs — one mates to your existing competitor harness connector, the other connects to a CURT brake controller
  • Quick plug design for fast, tool-free installation
  • OEM-quality construction for reliable, road-safe performance

The CURT 51520 adapter harness is an ideal solution for anyone upgrading to a CURT brake controller without wanting to replace their existing vehicle wiring. Installation is straightforward and typically takes about one hour.
