Voltage supply

The HFM-SFI control module is supplied with voltage (fused/ unfused) at circuit 87 and 30 as follows.

To relieve the plug connections, voltage is supplied in some cases through several pins connected in parallel with bridges.

-----------------------------------------------------------------------------------------

GND connections output stages

Several GND connections of the ignition output stages and the GND of the electronics are bolted on close to the HFM-SFI control module.
