Did you reverse polarity?


You didn't state what year but this sounds like a security issue, have you performed the shut down procedure listed in the owners manual? If you don't have an owners manual get one, sometimes you can find them in PDF format online. You can also try this: battery connected, from inside manually lock the doors except the drivers, with key in hand exit the vehicle close the drivers door and using the key manually lock the drivers door, that should have made all the lights and stuff stop, if it didn't then this procedure will not work and you will have to do what the manual suggests. now if the procedure in the owners manual does not work then you have a fault in the security system hardware and that will have to be checked out by someone who knows this system.
