Mine has been plugged in for almost a year and has no issues. A diode to prevent reverse flow is logical, but I don't see what the problem is? Maybe with a different Tekonsha controller? My P3 works properly with my trailer, whether it's plugged in or not.
The issue has been occurring when using the manual lever on the controller. We do not install many P3 controllers - it is feature rich and may have an option in the menus to disable lamp illumination with manual brake activation.
Your analysis makes sense, and I will take the time to add a diode the next time I do some electrical work. Thanks for the in-depth information. I certainly don't want to have any inadvertent electrical problems or codes thrown while I'm on the road...
Regardless of the ratings, Wrangler has a short wheelbase, when it comes time to stop you don't want a trailer pushing the tail end of your vehicle all over the road. If you can get some brakes on your trailer to help prevent it from killing you in the event that you need to slow/stop suddenly at highway speed .. I'd definitely suggest getting them.
it has the wrong connector (male vs female) will not fit our jeeps.
Thanks for the info. Appreciate it.
