Installation Notes and Tips

Verify vehicle year, make, and model before ordering, since fitment is limited to the listed applications. This assembly uses one rectangular connector with a male terminal configuration and includes a wiring harness for electrical connection. Mounting hardware is not included, so reuse existing hardware if serviceable or source the correct fasteners separately.

For best results, inspect the sealing surface and surrounding trim before installation to help maintain proper lamp fit and reduce the chance of moisture intrusion. Confirm bulb and connector alignment before final assembly.
