4 months after I bought this, I go to tow a trailer...no brakes. Exactly the same problem I had before. After some troubleshooting I find I have power to the back side from the brake controller (truck side), but no power to the trailer side of the plug. So, I start testing continuity and find there is absolutely no connection through the adapter. Well, there went $35!
