Output: 4-way flat trailer-light connector

Installation Time: Typically up to 1 hour
Connector Location: Stored outside behind the rear bumper when not in use and routed to the center hitch opening for towing.
This Traverse uses a passive exact-fit connection at the driver-side rear lamp harness above the muffler. The flat-4 remains outside the cabin and is protected behind the bumper when it is not being used.
1. Supporting and Lowering the Rear Exhaust
The muffler is supported before the rear hanger is released when additional room is needed to reach the factory connector above it.
2. Releasing the Factory Lamp Connector
The protected connector is separated without damaging its locking tab or pulling on the vehicle wiring.
3. Installing the Passive Inline Harness
The exact-fit connector is inserted between the original housings and checked for complete engagement. No factory lamp wire is cut.
4. Securing the Exterior Flat-4
The lead is routed away from the muffler, heat shields, and suspension, then rolled into a protected exterior location behind the bumper when not in use.
5. Testing and Restoring the Exhaust
Running lights, brake lights, both turn signals, and ground are verified before the exhaust hanger and any removed retainers are restored.
Our Wiring Standard: Every lighting output and the ground circuit are function-tested before removed trim or underbody components are restored.
