Try changing out your PS fluid and flushing the system. could be that your fluid may be foaming up. Air bubbles entrained in your fluid are compressable and will cause a soft pedal. If you dont already use it, refill with ATF4 syn trans fluid. Could be something as simple as this.
Does your speedometer work? If not, probably the speed sensor in the rear diff went out. It is easy to change.
If it does work or it doesn't and you just want to verify the problem, have someone use a scan tool to pull the trouble codes from your abs module. Diagnose it from the trouble code. Better than 90% chance if the speedo stopped, the speed sensor went out.
You also mentioned your pedal was soft. Is it abnormally soft. Hydro boost units can have a spongy feel to them if you compare them vacuum brake booster equipped truck. If you drive it normally, you will never notice it but if you are checking it and start pushing on the pedal hard you can over power the resistance of the hydro boost.
i have the same problem everything works but cruise i get a abs and brake light when i go over 60 mph i replaced the rear speed sensor before this problem bc the speedo quit it was good for about 2 months maybe i should try a dodge oem sensor?
Power steering pump or fluid will not trip the ABS / Brake light combo.
Brake fluid might but it would have to be seriously black.
As for me I'm also fighting the ABS / BRAKE light. What happen to me is the driver side cable broke in half. So I bought the new driver side sensor and installed. But now the passenger side on the driver side are mismatched and no longer so the ABS computer keeps setting the code because of mismatch between left to right. So now I got to replace right side too. I always suggest replacing both sensors as a pair and I didn't heed my own warning and got hung on it too. (D'Oh!)

Mopar man. Thank you for saying that because my reservoir is dark. You can clearly see where the fluid is from te color of the fluid. But my pitman arm is leaking pretty bad that's we're the air bubble could com into play but the steering feels fine. SPEEDO still works its off by 5 but it's always been. I'm hooking up the scan gauge as we speak ill be back with codes
