There are a couple troubleshooting steps we should try out on your # C59496, but I think we can isolate the issue down to one probable cause. First, make sure you're testing the smaller red wire (which connects to your brake lights) for voltage; the larger red wire is going to be the power wire that is connected to the battery. You also need to make sure that your ground is connected firmly to a clean, paint free surface. If you can confirm that these are both the case, the converter is... view full answer...
