Well, ours was built in 1992, has no 'mapping', no CAT, just a nice lumpy 2.5 turbo with a battery to start it........However, they do the same switch with a fuseable link, so that everything still works, but if a thief tries to start it without the key, zilch.Only problem is on a modern van each time you used it you would have to go to a main dealer to get the electronics re-programed.
