Hello, I recently finished swapping my 2011 se from automatic to manual. I am having some trouble with both the reverse lights and the speed sensor, and I’m not sure how to diagnose them. The speedometer doesn’t move at all. The car runs and drives no problem for about 5-10 minutes, but then the lack of speed sensor input throws a code and I go into limp mode. As for the reverse lights, they turn on and stay on with accessory power. I’m sure I just screwed up the hack job wiring I did, but I have no idea how to go about finding the fault. What should I be looking at first? Any help is appreciated!
