Depends on a few things. If you are on a test stand you probably don't need to wire anything since the ignition system is usually mounted on the control panel. If you are building your own test stand then you'll need to decide which ignition system to use and then wire it according to the instructions. You may or may not want to run an alternator. The starter wiring depends on which starter you use and how you want to trigger it. So the answer is "it all depends".
