I have a plug in my bed, yes i have used a test light and all bring power except the bottom one and the bottom left, even the brake lights work but the controller still reads not connected. I'll take a look at it tomorrow im not sure what brand it is but it goes off the pressure you put on the brake pedal instead of going all the way up to the number you set it on, thats what i like about it compared to my old controllers.
