Well I didnt really remove it as I just unlugged it from behind the drivers side headlight. Basically I drove 400 miles before the ses light came on, I figured it would come on becuase of this and I am throwing the p0410 code. But what I want to know is it bad to have the system unplugged? Can it be erased with ls1edit when I get it?

 

It can be erased with Edit. Its purpose is just to light the cats off quicker. The only damage being done is to the enviorment.
