I had some issues with my clutch safety switch, took it apart and cleaned it, put it back together and all is good. Sometimes it can get misaligned on the rod, you might want to work it back and forth and make sure it is running on the rod correctly.
While I had all that apart, I tapped a wire off each of the two wires and ran them to a momentary push switch that I mouted on the dash, if for whatever reason my switch goes goofy again, I can just pusk the switch to have the same effect that the stock swith does, it makes ground and allows a completion to the starter. If you jump those wires, you effectively loose the safety aspect of the switch, you'd have to be anal about making sure you are out of gear when you start your truck, and if others drive your truck, this could be a problem. Nothing like hitting the starter without the clutch depressed and starting your truck in gear . . all but soil your pants, and whoa be it to whatever you might run over because this can happen.
Plus, after starting your truck, the switch circuit goes open, it is involved in your cruise control system, some have jumped the switch and had problems with their cruise control.
