Well, I have the console installed and it was a little harder than others have described it. Thank God I had a good friend who is mechanically inclined helping me out. The console for the Denali worked just fine. There were a few other items not mentioned by others on here that you should be aware of.

 

First, the wiring harness on the middle seat is a bear to strip out of the seat! I had to do some major disassembly on the seat to extract the harness. If there is a junction somewhere it is not under the console. Because of this I was hesitant to cut anything off of the truck. I ended up using the seat harness to wire the back half of the console. The rear 12V outlet, 12V outlet in the console compartment and the USB/SD Card/ Mini plug connections are all covered here. Unfortunately there is a switch and LED that are not for the console lid. I ended up stripping the harness that comes with the console. I figured I could replace that harness if I messed up. I took the entire harness apart and used the wiring for the switch and LED lamp. I extended one of the wires due to the routing to the front of the console along the same path the original harness used. Problems were that with the original harness the plugs did not all reach to the new locations on the console. I had to really stretch things to the rear most 12V outlet. I also had to cut some of the sheathing material for the two connections in the console box as they go out two different paths.

 

On the hook-ups for the plate near the front of the console.... The 110V plug is just transferred from the dash outlet as you get rid of that panel. Same can be said for the 12V outlet. Problem is you now have two 12 volt outlets! I just jumped from one to the other and soldered the wires. I got the plug from the harness that original came with the console as I had already started cannibalizing it. You only need about 6 inches of wire with the plug. Now, that only leaves that stinking 3X USB outlet.

 

My thoughts on this are simple. The original console wiring does not include any of the front wire connections meaning they must be wired separately from the truck. The only harness connections are for the USB portion of the plug in the console and a huge 40+ pin plug that is major overkill with about 8 wires only being used. So my thought is that since GM decided to wire the two rear most 12V outlets together that I could wire the two front 12V outlets together. Now for that stinking 3X USB feature... I believe there has to be a separate connection on the radio for this additional cable! OR a two cable connection on the OEM console trucks. So my thought is I am going to check the radio for this connection. I'll bet there is a blank spot for it somewhere.

 

I still have to run 12V always to the two wires I ran forward for the LED lamp in the console box. I am going to put on a Delphi wire plug to both ends to be able to unplug it as needed. Also, just an FYI, the two rear most 12V outlets are on with ignition power only as the two front ones are 12V with the key off.

 

Lastly, there are quite a few pieces that are no longer used from the dash when you install this properly. Another item is a brace cover going from the dash to the floor. You must remove this cover or the driver's side console cover will not fit.

 

More to come....

There is a second port on the HMI where the front USB ports are wired into, but the port is not there unless you have the console from the factory. Different part number. On the 2014 trucks anyway. On the 2015 trucks they all have the 2 port version. On the bench seat models the second port connects to the single USB in the glove box. Check my gallery, I pulled the glove box and took some pics of the HMI in a 2015.

All righty then. Does any one know if the HMI is the box that is replaced when updating to the Factory Navigation system?

if you did what i did ( post 321 in this topic) it could have been easier because everything are already in the console so this way the light in console and switch can work as oem ......and also you didn't have to modify for the rear 12v outlet

.......only need to exchange the usb cable because connector and also for the 3 front usb you need to plug it in hmi and running 12v+ and ground even if they can't read music from usb key but at least they can be use to charge cell or something else.........

 

but if everything work for you , it is the main objectif :)

you will love the very big trunk in the console :)

Where did you find the big connector on the seat? Is it under the passenger seat carpet?

The jump seat trucks don't have that connector. People have been cutting the big connector off the console harness and splicing the necessary leads.

 

The portion of the HMI in the pictures is directly behind the glove box, near the in cabin air filter.

I had a 2014 Black Sierra that I swapped a jump seat for a full console. Yes it was worth it, but I had to sell the truck and before selling it I swapped the seat and console back. I now have a complete black console with a cup holder that I purchased separately. If you're interested in it, please let me know ([email protected]). It was installed for 4,000 miles and is in new condition.

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.

      Seems to be Missing a lot of Updates

      By newdude · Posted

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.

      What did you do to your "other" car (aka musclecar) today

      By KARNUT · Posted

      We try to make cruise the coast. It’s where our favorite casino is. I only want to spectate. Never took a car. Always had one to take. I belonged to a club once. Even when I used to drag raced. It was during test and tune. Probably because I’m not a night owl, party person.
