VB40a 40amp Voltage Booster Installation Guide

Wiring the Voltage Booster

1a – Follow the picture below for wiring your VB40aX1 single fuel pump booster. The Red wire should go to a

switched 12v source that is key on power capable of handling 50amps. The Black wire should be grounded to

the chassis or another suitable ground location. The Blue wire should connect to the Positive (+) terminal on

the fuel pump, and the White wire will go to a switched ground to activate the booster.
