Extend: some extra length to the outputs of your harness for your HID Ballasts or high beam solenoids with these 9006 Male >9006 Female extension cords. Oversized: If you're retrofitting a big truck or mounting your ballasts in an unconventional space - a universally sized relay harness may not have the length you need. Here is the answer. Universal: 9006 Male inputs to 9006 Female outputs with 12 inches (30cm) of 14 gauge wire in between, then protected in a heat-resistant TechFlex mesh for an factory-look. Sealed: metal pins with rubber grommets on both ends ensures the longevity by keeping moisture out of the connections.
