Can't get my 2016 Ram 2500 diesel to go from orange to blue when insert key for programming

I have ran a check on the wires using the flashing blue light method and it's all good.

I figured it myself. I did not have the blue and light blue wire hooked up to the T-Harness. Hooked it up and was able to program the unit. Lesson learned, those U-Tube video doesn't say anything about hooking up those two wires. If you look at the installation diagram, be sure to look at the one with the T-Harness as the one without the T-Harness does not need the wire hoooked up.
