94' LT1 vats question

im doing an lt1 engine swap and just have the computer. no resistor key or theft deterent module.

i need to produce the 50hz with 50% duty cycle signal to the fuel enable signal wire that goes to the computer so that it will enable the fuel system... more importantly the injectors.

does anyone have a simple and legible diagram of passkey2 bypass module. the one that uses the 555 timer, a couple of diodes and a couple of resistors and some other stuff... i don't really know the entire parts list because i haven't seen it done or a clean legible diagram of it.

thanks in advance.
