Weather Pack connectors are incredibly handy for wiring up automotive projects. They're weather resistant, simple to assemble, and reliable. We now offer kit packages for these connectors in a variety of sizes. "A" packages are for 20-18 gauge wire, "B" packages are for 16-14 gauge. Please note that some Weather Pack connectors come in several key versions - while our packages all use the same keying, they may not always fit Weather Pack connectors from other sources. These connectors are genuine Delphi parts.
