What this harness does

The Axxess AX-TGM2 is a T-harness that plugs into the factory wiring of select 2010-2014 General Motors vehicles. It allows a remote-start module to be installed without cutting or splicing any original wires, preserving the vehicle’s electrical integrity.

Reliability over repeated cycles

Because the harness uses the factory connectors directly, each start cycle routes current through the same pins the vehicle was designed for. No solder joints or crimp connectors are added that could fatigue with temperature swings or vibration, so the connection remains stable over years of daily remote starts.

Questions about this item

Does the AX-TGM2 T-harness draw noticeable power or generate heat when the remote-start system runs all day?

The T-harness is a passive wiring adapter with no active electronics, so it adds no measurable current draw or heat during extended remote-start operation.

What existing remote-start module or vehicle interface must already be present for the AX-TGM2 to function?

The harness plugs between the factory wiring and a compatible aftermarket remote-start unit; that module must be purchased separately and matched to the specific GM vehicle.

Will the AX-TGM2 work alongside the original steering-wheel controls and factory infotainment in a 2013 Chevrolet Malibu?

Yes, the T-harness is designed to retain all factory features — including steering-wheel controls and the original radio — while adding the remote-start connection.
