2021 Ram 3500 6.7 Cummins Smart cable location?
Way to go HPT for adding support on the new 6.7! I emailed support last week to see where the smart access cable plug is located on 2021 Ram 3500 6.7. Haven't heard anything back yet. Does the ECU need to be unlocked? Or just needs the smart cable? Thank you for your help!

For anyone searching the SGM is located behind the cluster on a 2021 3500 6.7 Laramie Cummins. Tried to read file out but got an error when it was done. Trying to get that rectified now through support

If you take the cluster out and install ECRI adapter at the SGM it will read. I?ve done it on a few 2021?s and it worked fine.

did you need to unlock the ecu before flashing?
