The X & R will also run with the dash unplugged.

Thanks Kev....
Trail Tech it is then...

Trailtech doesnt show fuel now warnings, neutral and other leds
To my current understanding those wires going to stock speedo are kind of digital bus decoded by it, right?
Or are different led lights signal transimmited by separate wires?
I got imo 100r50 and considering trail tech as well not sure about model strike or voyager
