I found a secret in my truck!
So I was doing some poking around, and I found this really neat feature. Its a diagnostic test mode, with lots of cool features!
To enter the test mode follow these instructions!
1) Insert key, do not turn.
2) Press and hold ODO Reset button
3) Turn key to "ON" but not start.
4) Keep holding the button until you see TEST
You may now start the truck and it will stay in the test mode. If you want to get out of the test mode hold the ODO button for about 10 seconds.
You are now in the test mode! Pressing the ODO button will cycle through the MANY MANY screens that your ODO will display. A few are a digital tach, digital speedometer, numeric fuel level indicator, transmission temperature, digital battery voltage gauge, stored DTC codes and more!
Sorry some of the pics are fuzzy. I had to set my phone/camera on the steering column so I could drive for some of the tests and it didnt want to focus close up.
Bulb Check:
Digital Speedometer:
There is also metric speed for you metric folk.
Digital Tachometer:
Engine Temperature (F):
Diagnostic Trouble Codes:
Door Ajar: (Would be represented by numbers)
Voltage Gauge:
Gauge Test (Full Sweep):
I also took a couple videos:

EDIT:This was later found, and I thought I'd post it here.

GAGE - Carries out gauge sweep of all gauges, then displays the present gauge values. Also carries out the check sum test on ROM and EEPROM.
All segments illuminated.
Illuminates all odometer segments.
bulb
Illuminates all micro-controlled lamps and LEDs.
r ####
Returns to normal operation of all micro-controlled lamps and LEDs and displays hexadecimal value for ROM level (used when requesting assistance from the hotline).
nr####
Displays hexidecimal ROM level and type as stored in non-volatile memory (NVM).
EE ##
Displays hexadecimal value for EE level (used when requesting assistance from the hotline).
dt ####
Displays hexadecimal code for the final manufacturing date.

I looked up the two DTCs I got from the gauge cluster and they appear to be gauge cluster related only. I think it will only show the gauge trouble codes. It would be cool to read them all thought!

3 things I miss from my Ram: DTC's from the ODO, A-Pillar handle, and the double-storage middle seat.
Pretty much it tho!
