Can I reprogram a EVO-GM3 to work on 2011 GMC Sierra

Question

I have a EVO-GM3 from another application, can I i re-install the module on a 2011 GMC Sierra 1500 with a new wiring harness (THAR-GM4) and a new flash?

Answer 1

yes you can, just reflash the module to you specific car and make sure flash limit did not exceed.

Answer 2

No, The GMT3 harness is for 2014+ Chevy/GMC trucks. https://fortin.ca/en/products/evo-rs/evo-gmt3/

The evo can be re used as long as it is not older than 5 years, but it would require you to get either a GMT4 harness or purhcase a generic harness and hardwire it into the truck.
