Hi there. It seems that the dashboard lights are grounded to the turn signal switch circuit. This will make your dash light come on when they are not to come on. For the indicator light staying on issue is the power is attached to the running lights circuit and not through the flasher unit. This will make the light come on but not flash. Make sure that all of the turn signal wiring is hooked to all of the dash lights and is powered through the flasher. If you need further assistance with your flasher indicator lights not working properly, then seek out a professional, such as one from Your Mechanic, to help you.
