SPAL ICB1 system has been designed to be used with after market audio, mobile media, cruise control and navigation systems. It has outputs including reverse gear, sidelights, handbrake, clutch, vehicle speed, RPM and ignition, allowing the product to be installed easily in the vehicle, working from the vehicle CanBus system.

The ICB2 includes the same outputs as ICB1 but has been designed for use with aftermarket satellite and alarm systems and therefore has additional outputs including drivers door, passenger doors, boot and bonnet open/closed. This allows for the new security system to be installed using the original vehicle sensors. It will also detect signals from the vehicles remote controls for door locking and unlocking.
