Step up your wiring game with our most complete Weather Pack kit yet! This expanded 755-piece set builds on the success of our 460-piece kit by adding 5-pin and 6-pin connectors—plus an even greater variety of terminals and seals to support a wide range of wiring sizes. Like all DIYAutoTune products, this kit was designed in-house to meet real-world shop needs. We’ve tested other kits and found them lacking—so we created one that exceeds expectations.
