In which your narrator is flummoxed by a bit of electronics.

So, I’m a firm believer in “Trust but Verify”, so I wanted to be sure that I knew which wires in the trailer wire were carrying which signals to the junction box*. Because I can’t be both in the drivers seat of the Honda and sitting at the trailer tongue with a multimeter, I enlisted the help of the youngest offspring.

He loved sitting in the drivers seat, stepping on pedals, flipping levers and things were going pretty well.

I was able to confirm my ground, hot, turn signals & marker lights. That left two terminals unaccounted for and no trigger voltage for the trailer brakes. No matter how hard he stepped on the pedal or pressed the override button, I wasn’t getting voltage on either post, but I was starting to get pretty hot under the collar.

Time to pull the dashboard apart again and make sure that everything was working correctly. There’s only four wires between the controller and the Honda, so it shouldn’t be too hard to sort.
