    2015 Tahoe PPV
  1. Problem solved....below is my post copied from the “Denali Cluster in SLT” thread... Well, as it sometimes seems to go, it’s the “easy” things that can bite us. After hours and hours of troubleshooting and some serious above and beyond “service after the sale” from MVI, the culprit was found out yesterday. It turns out that the new pins I had added in the cluster harness did not have a good connection to the new wires to which they were crimped. (Had I taken 5 minutes to check continuity BEFORE I installed these....hindsight...) Fortunately I had a second set of terminated leads already made up and after checking continuity on each of them (one of the new ones was bad too; thankfully I had one to spare) I proceeded to replace the original set and just like that we went from this... To this... Thanks to those who offered their assistance but just as those posts were made I was making those elusive final (re)connections. So yes, with the right amount of patience, prayer (literally), and professional help this ambitious build can be done. Thanks again to Anthony at MVI for the harness kit and the rock star level troubleshooting help! (FYI: MVI offers pins with terminated leads for a very nominal charge. IF there is a next time for me I’ll be adding those to my order.) Also thanks to Chris at WAMS for the seamless integration of the cluster, HMI, and radio and the necessary front end communication to ensure I was sourcing the correct parts. If I can be of assistance to others, especially those with Tahoe PPV’s (this is #3 for me), please let me know.

  3. Denali cluster in SLT

    Has anyone done this Denali cluster upgrade PLUS the MVI IO3 to IO5/IO6 CarPlay upgrade? I have a WAMS-programmed Denali cluster that now works independently of the newly installed IO5 CarPlay system (which also works great on its own) but I have no audio/media/phone info in the cluster. I originally had a vinyl steering wheel without audio controls and I’ve upgraded to the leather with audio controls (I’ve added the necessary LINBUS wiring from the cluster harness to the clock spring harness so I have communication between steering wheel and cluster at least). I have also added the 5 MOST wires to the cluster harness but I cannot get the cluster to work with the HMI/Radio/CD (MOST) circuit. I’ve tried wiring the cluster in the circuit in every imaginable combination of devices (Radio/HMI/CD) but I can’t get it all to work (I bought MVI’s harness kit for the IO3 to IO5 upgrade, sourced the remaining parts, and had WAMS program the HMI/Radio/Cluster at the same time). Tonight I even tried bypassing the CD player as I read a few hundred posts up how every device in the MOST circuit needs to be the same model year (CD player is 2015, everything else is 2016+) but no luck. I’m working with a 2015 Tahoe PPV but I’m hoping there are enough similarities to a base model Silverado that somebody, anybody, may have already achieved this build. And yes, I have read all 960+ posts in this thread as well as the 160+ posts in the “WT trim with Color DIC, Steering Wheel Controls, IO5 Stereo Retrofit” thread. My world every night for the last week and a half is attached. Any and all help greatly appreciated!
  4. Has anyone who originally had an IO3 and upgraded to IO5/IO6 with an MVI kit been able to add the cluster into the MOST circuit? I have a WAMS-programmed Denali cluster that works on its own and now talks with leather steering wheel after adding LINBUS wire. I’ve added the 5 new MOST wires IN/OUT of the cluster into every possible location between radio, HMI, and CD player but I cannot get it all to work. I have noticed that MVI’s harness kit changes the order of MOST circuit devices. Whereas the GM spec shows Radio->CD Player->HMI->Cluster->Radio the MVI kit is Radio->HMI->CD->Radio. Any help appreciated!
