Nope... but it's seriously self-evident. All you're doing is killing power to the fuel pump (or injectors, if you chose to do so). For the fuel pump, locate the power wire (or the ground - all you need to do is eliminate the circuit), run in-line switch, done. For the injectors, wire the powers of all six to a common power, toggle the common power, done. (If your Z is a pre-94TT or pre-93NA, the latter method has the benefit of preventing your injectors from going bad because it eliminates the constant power that causes the coils to short.)

I tapped into the supply side of the fuel pump relay that is behind the kick panel under the dash where the fuses are. It was easy to mount an inconspicuous switch from that area too.
