The wires were fine, I've spent a better part of a year trying to track this down. I even added more grounds just to make sure. I just went with the solenoid because then I can have a 6 gauge wire from the battery to the solenoid, then a wire from the solenoid to the starter with a 14 gauge wire from the top post of the solenoid to the original signal wire. Meaning I need less volts to start the truck.
