My 2003 Ram 1500 displays no buS in the odometer and no gages work. All the warning lights are on...engine abs etc. I went under the hood and found a connector/plug its black with a red slide on it has two wires coming off the harness that goes through the firewall one is blue with a black stripe the other is pink. I moved the slide back and forth started the truck and everything worked again....Im like cool must have been loose....well they went out again and messing with this plug don't bring them back now. What is this and what does it have to do with my gages? Any help is greatly appreciated.

 

Loose plug to the ABS controller was the culprit.

 

I am having the same problem. Where might I find this ABS controller plug?

 

Problem solved. THANKS.
