Got NX installed, sprayed and my car TURNS OFF.... WTF!?

Got it all wired up right, solinoids were clicking, everything was in perfect order. I go out to spray, hit it and the car TURNS completly off. Tried to start it... nothing. After some trouble shooting I pull the cover on the fuse box in the engine compartment and find two 40 amp fuses blown. Im assuming these are for the starter and ignition. My question is, why in the blue hell would THESE fuses blow when my nitrous isnt even related to them?
