So i tried changing my tail lights with aftermarket ones and after the installation nothing appears to be working. I changed it back to stock, and to my surprise not even the stock is working anymore. I think that somewhere along the way i must've done something stupid. i checked the fuse in the cabin and its not blown, checked the bulb and its fine, sockets doesn't look burnt but aren't getting power on both sides. i want to check the relay, but i don't know where it is located. I'm desperate for answers at this point. does anybody have any ideas?
