So I was bored Sunday and decided to install the new Raptor single mode shift light for my 748 hp 2012 zl1. Followed the instruction and tapped inthe the number 3 coil pack because it was easy to get to. I cranked my car for a test ride and it ran like crap, missing like on 7 cylinders. I made it back home and cut the wires I taped back off and made a test drive, not missing but did not feel as strong as it usually does, just not right. Back home and disconnected neg from battery and another test ride, way worst, number 3 and 5 coil are not sparking at all. Check everything with the connectors and evn swapped coils to the other side of engine, they worked there but the ones I put in 3 and 5 are still not sparking. Does anyone have a clue what my dumb--- has done to my car or any idea of what I can try. I even ordered a new coil harness today nut wont get it til Friday. I am loosing sleep because I busted my car. She only has 4900 miles so it should not be stuck in my garage, Any help will be much appreciated,

The Dumb---
