CURT 51531 is a universal splice-in brake-controller harness with a CURT quick-plug connector and vehicle-side pigtails. It includes circuitry for select vehicles where brake-light backfeed or excess input voltage can interfere with brake-control operation.
Key Features
- Vehicle-side pigtails are spliced into the appropriate wiring; this is not a plug-and-play factory vehicle harness.
- Designed to reduce vehicle input voltage and eliminate brake-light backfeed that can trigger warnings in certain vehicles.
- Important: the vehicle brake lights will not illuminate when the controller manual override is used with this harness.
- Includes 24 inches of 12-gauge color-coded wire and protective slit loom. CURT universal wiring kit 51500 may be required separately.
