What can be used as a corrosion inhibitor in vehicle electrical connectors?

I recently had  to change a connection block and windscreen wiper motor controller unit on a Ford Transit Custom because of water ingress into the connector and the wiper motor controller unit.  What can be used as a corrosion inhibitor inside electrical connectors to extend the life of the connecting elements?

  • I see no reason why silicone grease would repel water any better than Vaseline or bog-standard grease. Whichever sort you use, the contact between the prongs and sockets will wipe it away. What you need is a good dollop of the stuff which prevents the water from getting near in the first place.
