THGM610 T-Harness

Written by: BetterDays from Ely, MN on March 17, 2014

2009 Buick Enclave
Crutchfield Customer Review (What's this?)

The world of remote starters is still quite complicated, at least to me. The wiring can be a nightmare and helpful information - at times - can be hard to come by. I installed this harness in a 2009 Buick Enclave. It worked well, is well-made, and saved me a ton of time wiring the vehicle. It's really the only way to go. My only gripe is that the manufacturer really protects their dealerships and it was hard to get ALL the information and diagrams that I wanted. The harness itself is very nice and I would recommend it.

Pros: Very well made, saves a ton of time wiring.

Cons: Dearth of wiring diagrams.

Product Research


THGM610 T-Harness: The XpressKit THGM610 T-harness works with the XpressKit DB-ALL interface module (607DBALL, sold separately) to help you install a remote starter system (STD/*RSR/RXT) in select GM vehicles. The harness has plugs that match the factory connectors of your vehicle to greatly reduce cutting and splicing into the factory wiring. Some hardwiring is still necessary for installation. The harness is compatible with DB-ALL GM6 and GM10 firmware.

Note: Please consult the Crutchfield Car Selector to see if your GM vehicle is compatible.

*RSR (Remote Start Ready): RSR is a function that enables the DB-ALL interface module to remote start the vehicle completely on its own. Consequently, there is no need for an aftermarket or an OEM remote starter in order to start the vehicle from a distance.
