The quad driver/buffer may have been able to absorb the "hit" provided you didn't run it too long..Their pretty stout..
On those, the usual config is one is reference pulse, the other is sender..AND one more thing, are you sure you got the right sender? GM also uses two..one traditionally on the left head ( 1 pin, Gauge) and one on the right head (2 pin Computer)..check to be sure you have the correct one.
