The electric conversion of the 1969 Saab Sonett required a completely new 12-volt system and instrumentation that could accurately measure system parameters: cumulative amp-hour use, battery pack voltage, controller temperature, RPM captured by a magnetic sensor, and other new-to-the-automotive-world data.

The original black fiberglass dashboard was retained, but re-purposed as illustrated below.
