interlock starter

So I was mucking about in the wiring and I fear that I have killed my bus. I have been kicking myself for not relabeling wires that the old labels crumbled off of, and not restarting the bus after every thing that I did, but I honestly didn't think anything I did would land me in such hot water...

SOS interlock? I was trying to bypass the interlocking system and Shorted the front panel. The bus can't be started from the driver's seat. The front instrument doesn't light up anymore. I assume it was shorted out.it won't start. The rear Diagnosis Start does work so the engine is ok...
