2020-2022 GLC Keyless Go Harness Connection

For Keyless Go harness installation for the 2020-2022 GLC (X205), the harness must be connected directly to the Keyless Go module.

The Keyless Go module is located on the driver side in the cargo area. Connect the Mid City module brown and brown/red wires into the Keyless Go module where the brown and brown/red wires are already populated. After making the connections, the brown and brown/red wires from the keyless go module should be going to the MCE module instead of the original OEM wiring.
