So I got a hold of a '92 240sx and I'm planning on doing some modification to the ignition cylinder and starting system, but I need some figures first. Does anyone know how many amps the starting system draws when you start the vehicle up? And how many about how many amps do the accessories draw when the ignition is in start? Also I'm pretty sure as to what the different wire colors mean, but it'd be much appreciated if someone would be kind enough to verify my identifications.

<EDIT> I went and took a look at the actual wires coming out of my ignition cylinder and I'm very confused now. If someone could inform me as to what color is for what and what it's HOT in would be great.
