Plug the iDRIVE connector into the vehicle's accelerator pedal. Be cautious not to force into position as this may result in bent pins in the plug. iDRIVE connector should fit easily into position. Although removing the accelerator pedal from the firewall is not required, it may make access to the plug easier.
Re-fit connector into the iDRIVE.
Using cable ties supplied, securely mount the iDRIVE cable in a position that will not affect the operation of the pedals.
Mount the control module on the dash in a position that is easy to access. You may want to check the position at night to ensure the display doesn't affect night driving.
