  1. There is a spot in the rear junction block on the frame. See this post -
  2. Sounds like OnStar antenna needs replaced due to water leak, this is a common problem. as far as exhaust manifold leak, it is a common problem on the older 6.0’s, uncertain on the newer ones. Look at all the exhaust manifold bolts and see if any have broke off. I had a 2009 that had this issue.
  3. Look at the RPO sticker for Z71 in the glovebox
  4. That or reach out to pgamboa on this site and see if he makes a harness.
  5. You are still going to need a wire harness for 2016+ HiD headlights in a 2015.
  6. Unless something changed, parking brake is mechanical.
  7. Dots come up in the windshield if you come up on something to fast. mirrors will power fold in when you press and hold the lock button on the remote. Will fold out when you press and hold the unlock button on the remote.
  8. Look in the glovebox for RPO AVF, if you have this, then truck was built after August 14, 2014. With this RPO, you need harnesses. Without this RPO, you need harnesses and a jumper harness.
  9. All 2001-2019 trucks with Duramax has 3.73 from factory. 2020’s will have 3.42 with the 10 speed Allison.
  10. You have 2 years or 24 months from in service date to use the 2 free oil changes. This will include oil change, oil filter, tire rotation and fill DEF on diesels. Everything else you pay for. https://www.gmc.com/gmc-life/how-to/scheduled-maintenance
  11. GM did not offer factory TBC on the GMT800 trucks, they included a pigtail harness to wire in an aftermarket controller. You also had to install a fuse and hookup wires in the underhood fuse box.
  12. It is plug and play. When you plug it in, it will ask you vehicle make and that’s it. also, head over to www.duramaxforum.com and ask your question in the LML section
  13. If you can get your hands on an Edge Insight CTS2, then you can run a manual regen.
  14. My 15.5 DenaliHD does not show Driver 1 or 2 and memory seat function works fine.
