Just to echo what other people have said. The heavy black earth cable should be to the engine block / gearbox. The heavy red one (permanent live) is in the correct location. The lighter gauge red/black looks like your Ignition switch which should go to where you had the black one.
You should really get a multimeter on these things and trace all your wiring. The way you had this, you would have done some harm, backfeeding the ignition barrel with the battery live. I think you'll also have your alternator going onto the live as well.
