Do these headlights plug straight into my truck's wiring?

Factory mounting points line up without modification. Test-fit the connector before final installation to confirm your harness compatibility — some trucks may need a simple adapter depending on existing wiring.

Will I need to adjust anything after installing them?

Aim should be checked after install to match your vehicle's headlight pattern. Your truck's service manual covers headlight aiming procedure — takes a few minutes with basic hand tools.
