Easily add alternator control, flex fuel sensor, dial input and a boost solenoid output, plug and play ready to rock, dial and solenoid included!
Again these Holley PNPs harnesses, you will need to have a newer Holley harness with the power tap connector so this can plug in, from there each one gets plugged into the respective device or sensor and with some programming (yes i have files that are pre-programmed easy to copy over) setup in Holley it can all work out as easy as you hoped.
here is a really nice video overview of the harness itself
also if you were looking for some use case scenarios, ideas and how to setup the dial do things, here is a nice overview for that with ideas and how to.
