Yes, it will work fine BUT you will need to use your original Hummer lens with it as the trucks and SUV's use a different front lens section. The lens part is easy to remove and reattach - just some plastic clips around the perimeter. Of course as I mentioned before, your mileage is stored in the cluster so your mileage is going to change unless you have the replacement reprogrammed with your mileage. You also must get one from a donor vehicle that has a gas engine - one from a diesel truck will not work.

Great thanks for the help

i used a 2003 denali cluster board and transferred my 2003 eprom to it. i believe the 2005 and up clusters moved the eeprom location. it is located closer to the right side clusters gauge then almost behind the right side of the bottom info screen like on the 2003. i also believe if you swap the eeprom you can add the transmission temp gauge to one that does not have one.
