• Troubleshooting Trailer Running Lights Not Functioning on a 2009 Honda Pilot
  Depends on the amperage draw of your trailer running lights and what the license plate light circuit or running light circuit of your 2009 Honda Pilot is rated for. If the taillight circuit of your Pilot can handle the additional draw of your trailer running lights you might be okay for a temporary situation like getting back home so that you can fix it. But I would not recommend this as a permanent solution as you could blow some fuses or damage wiring. You might first check the trailer...

• Adding a 5-Way Trailer Connector to a 1999 Toyota 4Runner
  I am not sure why the 4-Way on your 1999 Toyota 4Runner does not have the brake light circuit already. Normally on a 4-Way flat trailer connector, the brake light signal is combined with the turn signals for each side. If your wiring harness does not have this set up then you do not want to splice in a wire from the brake light circuit because that would cause both trailer lights to blink with either turn signal on. I have the perfect solution for you. You can install a 5-Way flat converter,...
