I believe that is is located under the dash on the steering column and you will see it makes contact with the brake pedal. It does look like a bracket, that wraps around the brake pedal arm. When the brake pedal is pressed down it pushes the cylinder switch together which closes the circuit and makes you brake lights come on. Check your fuses as well as your wiring to the brake light housing. Also make sure that you have working bulbs and the right bulbs are inserted. Sometimes, the bulbs look identical but the bulb will not make contact with the housing connector. Here is a nice explanation how to check the circuit. Hope this helps a bit, good luck.

Hitch plug or wires can take out vehicle lights, good point.
The brake light switch is on the arm from the brake pedal to the brake booster (under the hood). It is held in place by a snap clip that is nearly impossible to get off, so don’t. Buy your switch and a new snap clip and then take a large screwdriver and shove it between the top of brake petal and the switch. Work it in there and then pry the switch off the petal! That clip will resist for a little while but it will pop off. You may never see it again. After getting the switch off, work it forward until you can get to the plug and unplug it and hook up the new one. Work the new one back in place making sure the hook on the back fits over the brake booster arm and then snap it in place. Now to get the snap clip back on I use a long skinny screwdriver with double sided tape on it to get the clip in place over the knob that holds the switch and then use a second screwdriver to snap it on. Still a pain to do but this has worked for me.

That switch is working if the relay clicking when u press brake paddle
Bought 98 GMC 2500 ,brake lights did not work.Changed everything.Did not work.What I did know it use to belong to a contractor that used trailers all the time.Then I checked the trailer hitch connections.I saw a white wire grounded to the frame.I checked it with my volt meter.Found out it was hot .Disconnected it.Everthing worked.I found out through a friend of mine that a lot of guys that use trailers do this to disable brake lights on their trucks when using the trailer hitch.My brother in law pointed it out a month earlier that it looked odd a white wire was grounded to the frame.Us guys that work on our trucks all the time fix all the big things all the time.Sometimes others see things we don't.
