OK... here goes... a simple hookup for just the ignition system.
Get your battery and ground the negative side to the frame.
Positive side remains disconnected (for now).
Coming from the engine, you should have a plug for the ignition pickup with yellow, blue, black, and black/white wires. This connects to the ignition unit. Also coming from the ignition unit are green, black, black/yellow, and yellow/red wires. The green and black wires go to the coils and the black/yellow wire gets grounded. Reserve the yellow/red wire for now, this is power and we'll connect it later. Depending on your year, there might also be a brown/white wire. Skip this one.
Now... on to the solenoid. One of the studs should have a thick wire going to the starter motor and the opposite stud should be connected to the battery positive terminal (OK to hook this up now). There will be two thin wires from the solenoid as well: Black and yellow/red. Ground the black wire and leave yellow/red alone for now.
Next, the coils. Each coil should have a yellow/red wire. Connect these into the yellow/red wire coming from the ignition unit. When you're ready to try to start the bike, connect those yellow/red wires from the coils and the ignition unit to the positive terminal of the battery. The coils and the ignition unit should now be on.
Finally, in order to start the bike, touch the yellow/red wire from the solenoid to the battery positive terminal. Make sure the bike is in neutral. Stop touching the yellow/red to the positive terminal of the battery when the engine starts (assuming it does).
You have no charging system or anything else hooked up at this time, so don't keep things connected like this for too long. Also, you have no fuse for protection, so make sure you get the wiring correct or flaming wires may result. ;D
