I figured it out. I noticed as it was darker out that I only had one headlight come on when I activated the fab. So I started looking for ground wire issues, as I've read somewhere that's usually the case. Took apart battery terminals with no luck. Took mega fuse box apart and noticed the ground wire had melted a piece of plastic that I assume is to kinda hold it in place. Soooooo long story and a headache later it was the nut holding the ground wire to that terminal was loose. Made a solid connection to the plate hit the fab and had both headlights come back on, hoped in a fired it up. Thank goodness. This 14 silverado has been nothing but a pain in the ass for me. Electrical issues after electrical issues. My transmission module went, and after a week in the shop and 2200$ just in time spent diagnosing it, its another roughly 1300$ to get it the part and labour. And the way things are going I feel like it's a waste of money at this point lol
