Does anyone know how this works? I was under the impression that when a trailer was hooked up the computer would start tracking how many miles you have towed a trailer. When I was questioning the dealer on an aftermarket light bar I was informed the on board computer uesd the trailer plug and measuerd resistance to activate the towing counter. I towed a utility trailer aproximately 30 miles and the on board computer never recognized a trailer being hooked up. I used the 4 flat wire harness and all of the lights worked. is this something that only works when using the 7 round plu

I am interested as well.

This is cool, I didn't know about it. The break regulator is a different circuit that uses the 7 prong outlet to apply electric trailer breaks. It may be in there. I think the 4 prong outlet only takes care of lights.

I have a boat trailer with surge breaks and not break regulator in the truck, I'd love to have this feature.

It only works with the 7 pin connector

As was mentioned above, it does only work on the 7-wire connection. I wish it worked on both since I have a boat that uses a 4-wire connection and my tent trailer that uses a 7-wire connection. Only the tent trailer will add miles to my towing mileage counter. Maybe I'll look into changing my boat connector to a 7-wire and wire a resistor across the brake wires.

Has anyone put a 4-7 pin adapter and plugged their 4 pin into the 7 pin plug? Will that do it?

I have a 7 to 5 pin adapter for my boat. It still doesn't show the mileage.

The 5th pin is for reverse lockout of the surge brakes.

I have pulled a travel trailer 900 miles using the 7 pin connector and a Tekonsha P3 brake controller. I am unaware of this counter. Is it displayed on the EVIC? Where can I see it?

 

[mfifield01]

The brake controller from the factory has the mileage counter. I doubt there's anyway to use an aftermarket brake controller.

I am guessing since the above posters have either a 2013 or 2014 flavor Ram and I have not seen this on my 2012 it is only on the 2013 or later? Or am I missing something?

It's the newer factory controller. The controls look like this: http://imagizer.imageshack.us/a/img11/7645/2013ram1500trailerbrake.jpg


You can scroll through the cluster to the menu that looks like this:

Thanks, that splains it.
