i stripped a bmw of its emboliser not long ago. its easier than you think. i was abit gun hoe.. firstly i put some side cutters through the control until and large wiring loom bit got that crap out the way, then its simply a case of following the wires for the starter and reattaching the ends. alternativly if its been de-activated and not doing much might as well leave it there. i only removed the bmw one because it wouldnt start.
