6. Crimp one end of resistor onto each wire (see illustration). 7. Solder each of the crimps, as crimping alone is not sufficient to guarantee a reliable fix. 8. Tape full length of resistor with insulation tape to ensure that the wire provides the mechanical support for the resistor. 9. Ensure the BeCM goes to sleep after carrying out this modification, this can be achieved by the following procedure. 10. Ensure the drivers door is closed and the interior lights are switched off, switch on the ignition, switch off the ignition. 11. Open the drivers door and leave open, switch off the interior lights. 12. The message ‘Ignition key in’ should then be displayed on the instrument pack for 2 minutes. 13. After 2 minutes the message should clear, this will indicate the BeCM is asleep. 14. Refit connector and closing panel
