I think you will find that a fuse has blown and I am guessing that you have lost loads of your dashboard dials and some ignition operated stuff. It should be fuse 29 and once replaced it should blow again when you reverse your car again. This is because the reverse switch has gone on your gearbox. It has a multi plug going into it. Let me know if you can't find it.
