Fuel Kill Switch
 

I'm currently trying to hook up a kill switch in my friend's 1997 Civic DX Hatch. Is the wire (power?) that i'm gonna want to cut and attach the switch the yellow wire with the green stripe? If you need a picture, i can get one. The interior has been removed, we are in the process of taking the carpet out so we can run the wires. So i need to know which wire i gotta cut when i get working tommorow. The stuff we found in that car...
