Piemma,
When the copper wire is manufactured the last step before the insulation is the copper is coated with a thin layer of tin for corrosion resistance as to not turn green and oxidize. Good connectors are tin coated too over time this may wear and turn green. Real good plugs have gold plated pins, like on your fishfinder.
If your loosing all those gauges recently I'd head right towards the big plug.
