kill switch

What wire/location would be best to locate a kill switch in an '02 Mustang V-6?

i would suggest putting it under your seat ot in the glove box..

Or like i had on mine i had switches for all my neons and stereo equipment i just hid it inside of those, i had 8 gauges, mine was the 2nd from the right.

if there worried about steeling your car there not going to be flipping on all the toggle switches hehe
