fuel line cutter is a good idea to prevent car theft......... but some would just smash ur car if they cannot steal..........

btw as for the wiring, all cars are a bit different; better carefully check it out. normally the fuel pump is located under the rear car seat (new cars, older car with membrane pump is else where); the wiring would go down under the center tunnel, u can make a tap from there.........plus a switch then u go to go.............
