Adapter converting seven-blade connectors to five-pin flat configuration for towed boats and marine trailers equipped with surge-brake systems. The grey impact-resistant plastic body tolerates salt spray, sunlight, and repeated connection cycles without cracking or corrosion.

Silicone-injected terminal plugs seal moisture away from conductor surfaces, and the plug geometry accepts both GM-style seven-blade plugs and standard marine five-pin connectors without forcing.
