Questions about this item
What vehicle connectors must match the 56397 harness for it to plug in directly?
The 56397 is a custom wiring harness built for a specific vehicle application, so the factory connector on your vehicle must match the harness plug exactly.
Will the 56397 harness work with an older trailer that uses a standard four-pin flat connector?
Yes, the 56397 provides the vehicle-side connection; you simply plug your existing trailer's four-pin flat connector into the harness socket.
How can I confirm the 56397 harness is functioning correctly after installation?
Connect a trailer or test box, then verify that running lights, brake lights and turn signals on the trailer illuminate in sync with the vehicle controls.
