Please review the instructions before starting. Confirm vehicle compatibility and inspect surrounding wiring while the Headlight assembly is apart.

These harnesses are useful for routine lighting repairs and conversion projects. They help replace aged connectors without changing the overall setup. That makes them a practical choice for owners who want a straightforward service item.

The included butt-connectors support an easier installation process. They also help reduce guesswork during the wiring refresh. For many vehicles, this type of repair can improve confidence in the connection at the bulb plug.

A clean plug and solid wire lead can make maintenance easier later. It can also simplify inspection when the Headlamp area is already open. This is especially helpful when restoring older lighting components.
