Our take on the XpressKit OBDTHDGM2 Interface Harness

Databus interface harness saves time

XpressKit's OBDTHDGM2 interface harness comes in handy when you're using a DB-ALL databus module to install a security system in certain GM-built vehicles, saving you hours of installation time and wiring hassles. The OBDTHDGM2 allows plug-and-play installation in most instances, but may require additional connections of up to three wires in some vehicles. Warranty: limited lifetime.

Hands-on research

Product Research


GM OBD Snap-In Type T-Harness For DBALL (RXT only): The OBDTHDGM2 T-harness works with the XpressKit DB-ALL interface module (607DBALL, sold separately) to help you install a SmartStart system (such as the 607VSM200/607VSM250, sold separately) in your General Motors vehicle. Your GM vehicle must be equipped with factory keyless entry and remote start. The harness has plugs that match the factory connectors of your vehicle to greatly reduce cutting and splicing into the factory wiring and save you time. Some hardwiring may still be necessary for installation. With the help of the online configuration tool, you can select an RF kit of your choice to enable Factory Remote Start activation (RXT).

Note: The OBDTHDGM2 T-harness features a snap-in type OBD plug. Check your factory OBD plug to see if it is also has a snap-in type OBD plug. Factory OBD plugs with a screw-in type connector require the OBDTHGM1 (607OBDDGM1, sold separately).
