Shift Light

Does anyone know how to enable the shift light on a 2016 Challenger HC?
Got it "DONE" at the dealer the other day. You MUST have the shift light turned "ON", the floor shifter MUST be in manual setting (moved left) and last but not least "The large digital speedometer must appear in the Driver Information Display (DID). These instructions are nowhere to be found in any manuals that came with the car. I contacted the SRT folks twice and they couldn't figure it out. I hope this info helps someone out there , so they don't have to go through the same nut roll I did.
