No issues setting up, but still in the process of cleanly buttoning everything up. Wires are pretty stiff, so it's a bit hard to bend a certain way to fit and what not.
Tech support responded very quickly with questions and explained the reasoning for changes that were made.
Just a note for future buyers, the T-harness provided no longer includes the t-harness for the constant 12V + ground, so instead of tapping into the aftermarket harness for power to the Fortin, you now have to tap into your factory wiring. If you're not a fan of messing with factory wiring, another option is to run a fuse tap for the BCM to power the Fortin.
