Hey yall, just got my 5.3 swap all done up and I noticed a problem with the brake lights. When I hook up the battery the third brake light stays on constantly and my 2 main brake lights dont illuminate at all. I need answers and would like to know if anyone else ran into the same issue! 1997 C1500 5.3 swap. TIA!
