2019+ (T1) Denali / High Country Cluster Programming



This exclusive service allows for complete 100% factory correct operation of a T1 Denali or High Country cluster (that you can supply or choose to have us supply a brand new unit under the retrofit kit item!) into a non Denali or High Country truck with plug and play simplicity and no errors or more importantly tamper flags!! We can also suppress warnings/errors etc please email for pricing on those applications as they are custom. NOTE: The Denali style version is whats pictured above.

This service is 100% custom to your vehicle and options and can be tweaked for mods such as added OEM navigation, added front park assist, HUD hardware retrofit etc.

We will setup all clusters for Navigation regardless as it will allow you to turn off the speed limit menus and simply enable them if you retrofit navigation. We’ve found this to be the simplest method to make everyone happy and negate the need to send the unit back for additional programming.

Please note: In order to Utilize the Music, Navigation (if Equipped) and Phone menus you will need to have an IOS or IOT radio; the IOR does not have the bus wiring or capability to drive those menus.


Q: How does this work?
A: You can choose to have us supply the 100% correct OEM Brand New cluster by selecting the retrofit kit item OR you may choose to source a new or used cluster which is what this service is for. If you choose to supply your own Denali/High Country Cluster you first figure out your application (E.G. Gas US Spec and model year) and using the parts list below you source the appropriate cluster (new or used). If you wish to have 100% OEM functionality AND retain your factory or factory backed extended warranty you MUST have us supply a new unit by purchasing the retrofit kit item. You then place an order and follow the shipping instructions provided.  Upon return simply plug the unit in and you’ll be golden; yes it’s really that simple.

Q: Can you do this for Export (Metric clusters)?
A: Yes we can and we can supply them as well via the drop down.

Q: Will I lose any features?
A: No you should not lose any features that you had before.

Q: Will I gain any features?
A: You may gain some features as the Denali/High Country clusters have slightly different menus. We can also enable things you have added such as indicators for front park assist or the Navigation menu if you have added factory navigation which is why we ask for those of you with the IOS radio. If you have added FACTORY options that your truck didn’t have please put what you have added in the notes section.

Q: Can you delete warning indicators for items I may have removed from the Vehicle??
A: Yes we can, this would all be custom and priced as such, contact us for details.

Q. What Menus are included in the Expanded Menu Set?
A: A true un buffered/unscaled coolant temperature readout. The factory gauge is heavily buffered/skewed; This reads true coolant temp. Top consumers: Shows which features currently being used are costing you fuel economy; and how much. Economy Trend: Shows fuel economy on a scale of 0-30 MPG over the course of 30 miles. Individual Oil Temp and Oil Pressure Readouts. A combined menu that shows Oil Temp and Oil Pressure on one page. Performance Timer: Timer can be set from 0-60 or from any stop/start point you choose. Lap Timer (2020-21 only): Can be used to clock “laps” or any time between points/events. G-Force Meter (2020-21 Only): Shows instant and peak-hold Lateral and Longitudinal G-Forces exerted on the vehicle.

Q: What is the HUD Retrofit Option?
A: This enables the unit to drive a heads up display. Yes it can be installed no we do not provide support for that end of it but you should reach out to HarnessDr.com for wiring harness info to make that switch. If you have forward collision alert and are not 110% set on doing the HUD upgrade we recommend you do NOT choose this option as it will disable the LED Forward Collision Alert indicator.

Q: What is the Odometer Lock Option?
A: The Odometer lock  option removes the odometer hard lock from a cluster that has been tampered with or improperly installed/programmed (Odometer Showing ——).

Q. Why don’t you ask for my Mileage? What happens to my odometer?
A. Your odometer will sync to your vehicle at install at the correct current milage this plug and play with no user intervention required.

Q: What about my engine hours?
A: Generally these are reset to zero. These are not required at a federal or state level however if you wish to keep them we need a print out from a dealership using GDS2 software. They can print a report showing your vin as well as idle and total hours.

Q: Do I need steering wheel controls to use this cluster?
A: Yes you need factory (or properly retrofit) steering wheel controls to interact with the menus on these units.

Q: Do I need to send in my factory cluster?
A. No, we only need you to send the Denali cluster you are sourcing (if you are choosing to supply it)
