The VSS tells the computer how fast the vehicle is moving. The computer then uses that information, along with inputs from all the other sensors, to control the spark timing and fuel delivery. You do not need the VSS to make the engine run, but you may experience some hesitation or stalling. It won't hurt anything to run without it, but if you start to have problems such as a rough running engine or stalling when coming to a stop, I'd recommend hooking it up.
ok thanks, i think i will just mount it anyway just to be on the safe side
i finished the exhaust today
