Do these connect to the factory wiring without modification?

Yes, they're designed to plug into the factory headlight connectors. No harness splicing or rewiring required — just disconnect the OEM unit and connect the new one.

Will I need to adjust the beam after installation?

Test-fit both headlights and inspect the beam pattern on a wall or garage door before fully securing them. Slight vertical adjustment may be needed at the mounting bracket depending on how the housing seats; refer to your vehicle's service manual for proper aiming procedures.
