Okay, seems like everytime i get 1 problem solved, i get another. So this time i have a drain on my battery. I came out to a dead battery the other day. Replaced it and the next day dead again (today). As im running through all my wires, i noticed this ground that connects to the firewall...the truck runs fine without it and seems to run better actually but is it necessary? Thanks20160530_215032.jpg
