For your 2008 Ram 3500, the Redarc Tow-Pro Liberty # RED24FR you asked from is a great option. It communicates with the 7-way connector from the blue output wire of the # RED69FR pigtail.

If you have a factory 7-way, then you will simply wire color for color to the # 3020-S under the dash. If you have the factory 4-way, then you will connect this same way under the dash but the brake controller output (blue) wire does not run all the way back to the 4-pole at the rear; it stops at the connector that is located under the driver's side wheel well. In order to finalize the installation you must splice into this wire and continue it back to the plug and use the # ETBC7L kit to complete the installation.

If you have no factory wiring, then you will use the # RED69FR pigtail and then use the # ETBC7 kit to complete your wiring. If you don't have a 4-way trailer connector then you will also need the Tekonsha 4-way harness # 119178KIT as well.

Yes, it will work. You'll just need to cut the Lance 6-pin connector out and rewire it into the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box and RV Style Connector item #e99011. Here are the individual functions of that Lance 6-pin:…

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…

You are going to need to replace your 2 inch trailer hitch on your 2008 Dodge Ram 3500 with one with a 2-1/2 inch opening so that you can use your 40 inch hitch extender. For that you would want the Curt hitch part #C15809 which is a confirmed fit…

While we haven't had the opportunity to install the Curt #C15809, Curt #C15704, and Draw-Tite #DT45509 hitches, from what I could see in the photos customers have sent in it looks like the Draw-Tite will actually sit right up next to the bumper…
