- Fitment issues caused by non-OE-style electrical components
Installation Notes and Tips
Verify connector shape, gender, and amperage rating before installation. FH59 uses a female, square, two-connector plug-in design, so matching the original connector style is important for proper fitment. Confirm vehicle application by year, make, and model before ordering, especially on Silverado 1500, Sierra 1500, and Escalade platforms. Professional installation is recommended for electrical system service.
