NOTE:
ALWAYS double check your connections with a multimeter as colours or wiring may change.
ALWAYS position the 5A fuses on the fused connections, power and ignition, as near to the
connection point as possible (do not extend the fuse wires).
ALWAYS connect the power supply to the feed rst and then to the OBU, to avoid electrical primers.
