For those replacing their Voltage Regulator and needing a new Voltage Regulator pigtail here's just what you need! Comes with three weathertite butt connectors to seal it to the OEM wiring system. Just crimp each connector on and use a heat gun to shrink the weathertite tubing. Viola!  Our new plug eliminates a lot of charging issues from corrosion getting in the OEM plug over the years.
