Need fit a ignition switch cable to my orion 30amp dc to dc
As getting intermittent switching on when engine not running,
Alpha batteries say fit wire from ignition live to dc to dc removing the bridge wire supplied.
Fiat ducato start /stop smart alternator 2021 .

I do the same as Alpha suggests ... use the ignition line as way easier to locate. Simple place to tap into this is from the radio connection.
