stand alone voltage control and big 3 upgrade?
I have a 2005 yukon xl and am looking at doing a big 3 upgrade. My question is, there is a box on the negative battery cable of my truck. if I do the big 3, do I need to run the grounds thru this device? I think it is for the Stand alone Voltage Control, that is designed to adjust alternator output as needed and keep the battery charged at 80%. Will running the grounds away from this effect my truck's charging system?

A photo might help. Usually there's a red plastic plastic splice box in the positive cable where the cables for the alternator, starter, and battery come together.Minneapolis area - 1997 K2500 regular cab long bed, pushes plow in the winter, carries camper in the summer - 2004 4x4 Suburban 2500 8.1, pulls 30' Airstream trailer

@SurrealOne might know, his truck is just a year older than yours and he did a major electrical upgrade.

The 2004 trucks that I looked at did not have it. Maybe his did. Guess we will find out
