Problems with brake controler

I have a Tekonsha brake controller that I am having problems with. When I press the brake the light on the controller will not light up. So I went through all of the wiring and it all checks out good. I checked my voltage, ground, and brake light switch output. But I did find that if I ground the brake controller output it will light up and appear to be acting right. What do you guys think.Thanks

bad ground. maybe an issue at the plug or the trailer. That is my thinking.

Do your taillights work? If not, it's the Brake on/off switch attached to brake pedal.

Run a ground wire directly to the battery's - post and see if that fixes it. BTW, taillights will work no matter how bad the brake light switch is messed up.

Well I found the problem, the trailer had the battery power and the brake controller output switched in the trailer plug. After looking at everything else that's all it was, I can only wonder how long that trailer had been like that. This is the first time I noticed but I rarely pull it with a smaller truck . But its a 25k GVWR trailer so I think it really needs the trailer brakes with any truck smaller than a 2 1/2 ton pulling it or you can really tell its pushing on you when you are trying to slow down.
