Connector Location: Outside the vehicle at the concealed hitch, secured on the Stealth magnetic holder when not connected to a trailer.

Current GLC trailer wiring is installed only with the compatible Stealth towing package. Completing it during the original hitch appointment lets us install and test the passive system while the bumper is already removed.

1. Integrating Wiring During Hitch Disassembly

The open fascia and rear structure provide the protected routing needed for the passive module and towing connector.

2. Mounting the Passive Module

The lighting converter is secured away from water paths and connected without installing a programmed active harness.

3. Establishing Fused Power and Ground

The power feed and structural ground are protected and supported through every pass-through.

4. Routing to the Concealed Hitch

The output follows the Stealth wiring provision and remains clear of the exhaust, sensors, and removable attachment.

5. Installing the Exterior Magnetic Holder

The connector is secured outside near the latch so it is available for towing without hanging below the bumper.

6. Function Testing Before the Bumper Returns

All lighting outputs and ground are verified before the rear bodywork is permanently closed.

No Active Harness Installations: We do not install active factory-style modules. They cost more, often require programming, and may not allow us to verify every function before leaving the appointment. A small connection error that is immediately correctable on a passive harness can otherwise require another bumper-removal appointment.

Choose the towing package during the original hitch installation if towing may be in your future. Adding wiring later is considerably more expensive because the bumper must be removed again and the concealed hitch must be modified for the wiring hardware, repeating much of the original installation labor.
