I'm going to install the fuel smart system. Ill give it a go see if it really works. To install I need to know which is the signal wire and which is the constant power wire connected to the fuel injectors. One is black and the other white. If anyone knows or has a wiring diagram for a 2013 5.7L I'd love to see it.
