i just bought a kill switch for my 450r. i was wondering if anybody knows which wire is the coil wire and which is the gound wire at the key switch. you would think pro design would have sent a wiring diagram, but all the sent was so simple instructions to hook to coil wire and hook to ground wire. i went to the shop were i bought the bike and they told me to bring the bike to them. they want 75 dollars to install the kill switch. ( i see that happing) i cant wait till i get my hands on the factory service manual.
