To make sure you are getting the correct kit you really need to check your alternator and look at the plug that goes into your alternator. The VCMs are application specific and are determined by the alternator plug. Some vehicles have different type plugs for the same year and model, so please take the time and check the plug for your alternator.

What is a VCM?

It is a Voltage Control Module that plugs directly into your alternator (can be used with dual and more alternators) and allows you to charge at a steady voltage rate. It comes with a wire harness that allows you to run the controller inside the vehicle and can be mounted any place you would like. You can adjust the voltage from inside the vehicle and set it to what ever voltage you would like.
