Update for those of you that are interested...
What happened was somehow both front speed sensor wires had come unclipped from the last bracket closest to the sensor leaving them dangling.
Don't really know how this happened at the same time, maybe from last trail run or from high pressure wash afterwards, don't really know. Anyhow, the wires insulation rubbed off over time and shorted out.
Guess I need to keep an eye out for this in the future. Thanks for all the input everyone.
