Good To Know

Q: Why does the DL3 option matter for this harness? A: DL3 denotes a specific mirror configuration, and harness connectors vary by option, so matching DL3 helps ensure the plugs fit properly. A non-DL3 truck may use a different harness layout.

Q: Can I install this harness myself? A: The harness is a plug-in replacement for the driver front door, though routing behind the door panel takes care and basic hand tools. Confirm your truck year and option code first.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
