Hello New to the forum, thanks for having me I have performed a forum search for my problem. But could use a little more guidance if someone would lend a hand, I would appreciate it. In addition to what the title says I should add that I have aftermarket LED rear lights. The lights work up front, the back parking lights, turn signals and hazards all work. Just not the brake lights on the tail lights. Turn signals use the same LED's that the brakes do. No blown fuse. Got the test light out and started poking around. The wires coming off of the switch on the brake pedal all made the test light light up. All had power without pressing the brake, except for one, it had power when the brake was pressed. Then I got under the bed where the buss is, unplugged the one coming from the cab. Test light never went off when the brakes were pressed. After searching the forum I read a reply from crabtruck that mentioned a relay. He said when you press the pedal you should hear the relay click. I don't hear that. That combined with the previous testing I have done would point to that. Problem is I can't find it anywhere. Following the wires quickly went into a rabbit hole. And my searching for this relay has gone for naught. Could someone help me find this or tell me I'm looking in the wrong place? Thanks!
