I have the d1000, but I think they call it the d1600 now. Same thing, heavier than the S though but more power. Also before I purchased, I checked with Autometer and Aeromotive to make sure the tach and my fuel pump would work with 16 volts and they all do. My marker lights and headlights are also working fine, they were nice and bright the other night at cecil which was crucial driving around those pits in the dark! No need for a step down resistor.
