I have a 1995 c200 with a Scorpion alarm fitted,I only have 1 fob (with 2 square buttons and a slider on the side) it only works when it wants I need to get the control box out and send it for repair and a new fob, anyone know where it is fitted and does anyone have a wiring diagram so I can short out the relevant cables to allow me to use the car,when the alarm is disconnected:
