Most important is to not mess up dc power connection.? do you have a dvm? You can and should verify each connection with the ohmmeter setting. Most important don't make a short circuit between positive and negative leads of your power source. Check everything before powering up. I see there is a new larger wiring diagram here. You can figure this out, don't be overconfident without checking things out.
After getting power right, much help available here. But do find folk nearby, check websites of local clubs.
