Description:
One plug-in module that unlocks lighting control, drive mode and stop-start memory, on-board diagnostics, and PIN security
— all from your factory steering wheel buttons.
Amber Daytime Running Lights (premium LED headlights only)
Five selectable DRL modes, chosen from a menu on your instrument cluster:
White — factory operation, DRLs stay white
DarkPark — DRLs go completely dark while the truck is in Park, then return to stock white the moment you shift out
Day — amber whenever the headlights are off
Night — amber whenever the headlights are on
Both — amber all the time
DarkPark does something a stock truck can't: it shuts the front end off. Drive-in theaters, campsites, roadside stops, staging
lanes, photo shoots — dark when you're parked, normal when you're driving.
The amber output is commanded over the truck's own network using the factory LEDs. No bulbs, no resistors, no cut
wires. Fully reversible.
Memory Functions
Stop-start (ESS) memory — your setting is restored automatically at every start. Stop reaching for the button.
Drive mode memory — the truck comes back in the mode you actually want, every time.
Diagnostic Trouble Codes
Read and clear DTCs across nine modules right from the driver's seat — powertrain, transmission, drivetrain, brakes,
damping, shifter, body, cluster, and radio hub.
No scan tool, no laptop, no trip to the dealer for a code you already know about.
PIN Security
Optional PIN immobilizer blocks ignition until the correct code is entered.
Your code is a sequence of steering wheel button presses, not numbers — very hard to guess by watching.
Re-arms itself automatically every time the driver's door opens.
Installation & Control
Plug and play. Roughly five minutes. Nothing cut, nothing spliced.
Every feature is configured through a menu on your instrument cluster display, using the factory steering wheel
buttons. No app, no laptop, no extra switches.
