          *** At purchase, be sure to properly note whether you have a 2 pin or 4 pin oval regulator plug. Most will have a 4 pin connector with only the center two wires populated.  (Click the magnifying glass on the main product image to see the different regulator connector types)  Additionally,  in rare situations, some Duramax equipped vehicles have 4 wires going to the alternator. IF you have 4 wires going to your alternator connection/plug, we will need to install a special regulator in your alternator. BE SURE to check this. If you do have 4 wires, call us to place your order by phone.   515-897-4459
