What's the best way to hook up a cutoff switch ??

[michel schryer]

Here it is,i'm waiting for my kit to arrive to papa on the 2nd of april and it's going to be my first kit car and hopefully i'll love it so much that i'll want to build another one. The electrical side of it is my greatest challenge,don't have experience with electrical though i've been hands on cars before.
Is there somebody out there that has a wiring diagram of your cuttoff switch hook up and wich one did you use. I intend to use a oem starter relay in my circuit with a one wire alternator. I heard stories about some other relays or solenoid failing while the ignition switch was turned off and the engine woudln't shut off. Want to use it as an anti theft as well. I read some guys hook it on the neg. side and some on the pos. side. Can somebody elaborate on that. Can you show me how to hook the switch please.thanks guys.
