    • Custom connector end plugs into the built-in port beneath the dash of your vehicle
    • Other end plugs into the back of your electric brake controller
  • Compatible with time-delayed and proportional brake controllers from Curt

  • 2' Long, 12-gauge wires have protective covering to deter damage
  • Limited 1-year warranty


Installation of Curt Brake Controller Adapter

To install your Curt electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


This adapter plugs into the port on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, and it is taped to another harness near the emergency brake pedal.


No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

Sorry for the late follow-up. I just wanted to let you know that the brake controller and wiring harness I purchased through eTrailer worked very well with my 2008 Dodge Ram 2500 with the Cummins 6.7L diesel. Pictures are attached for your use, as required. The trailer was an 18-foot enclosed snow machine tailer with a steel chassis. I can't remember the empty weight, but it's substantial. We towed empty and full on dry and snow covered roads from Oklahoma to Colorado and back. Even with th exhaust brake on my truck, I can't imagine towing this load through the hills and mountains without a brake controller. It's been done before, but I would say it's an unnecessary risk given the more than reasonable prices at eTrailer...it was cheap insurance pulling such a heavy rig with my family on board. The controller was definitely not your top-of-the-line model, but the adjustability and controls were more than adequate for somebody who tows occasionally. A professional may desire more proportional controls and adjustability, but not much more. This unit peformed flawlessly. Thank you for your time. Please feel free to contct me if you would like any clarification on my statements or pictures.

This item easily plugged into my Curt brake controller and into my truck’s factory plug. Made for a less than 5 minute install; powering up the brake controller with no issues. Convenient is an understatement with this pigtail. Rig is 2007 Dodge Ram 2500 4X4 CTD.

I needed an electric brake control for my 2006 Dodge pickup but was having trouble finding one locally that would plug in to the factory installed plug. If it was a Chev or Ford it was in stock and I didn't want a universal that would have to cut into the wiring. I called etrailer to make sure what I saw on their website was correct and they assured me it was so I ordered it. It arrived, I instaled it and it works perfect.

Still working fine.

Dodge Ram Pickup

In hind sight I probably didn't need to order this item. Forgetting how difficult it was to access the connector on my Dodge Ram when I installed my first (now defunct) brake controller, I imagine it will be a greater struggle to get it to disconnect before putting the new one on. So I think what I'll do is cut the Dodge specific connector off the one end, cut the wires off my old controller and splice this pigtail into it, thus eliminating the need to remove the old connector!


Comments
My splice job worked as planned however I no longer own that vehicle.

Dodge Ram Pickup

My 07' Dodge Ram Quad Cab had a factory installed receiver hitch and therefore the plug to which this cable attached. However, I had to go to the Curt mfg website to find a picture of the actual truck plug. Once I found the plug which was buried up in a difficult spot to reach, the cable snapped in easily. It is sufficiently long enough to reach the controller cable if one installs the controller anywhere on the knee panel below the steering wheel.

I ordered a Curt Discovery trailer brake controller. Exactly what I was looking for and for a great price. Transaction was smooth and easy and the controller arrived within a reasonable amount of time. I liked the parcel tracking that showed the progress of my order.

The Curt wiring adapter made installation of the Curt Triflex brake controller on our 2008 Dodge Ram 3500 a breeze. Just plug one end into the brake controller plug and the other into the pre-existing plug-in all ready under the dash, then added a couple zip ties to keep it up and out of the way. It couldn't have been any easier. The plug in connection also allows the brake controller to be moved easily from truck to truck if needed

ordered to hook up a curt brake controller in my 2007 Ram Megacab,perfect match up to the factory harness,if it was only about 6" longer i could have mounted the controller where i wanted it to go

I used this connector with a new brake controller that I also purchased. It was very easy to connect to the controller & truck's electrical system (under the driver's side dash). So far it's working beautifully. As always, etrailer was excellent with their advice, shipping, and follow-up emails. I have had great experiences with them since 2010.

Great product and great service from etrailer.com. It's wonderful etrailer makes it so easy to match the brake controller and adapter harness for your respective vehicle. It took me a total of 10 minutes to install on my 2006 Dodge Ram 2500

2009 Dodge Ram Pickup

Order the wiring harness for my 09 Dodge Ram, was extremely easy to install, the plug under the dash was facing straight out and easy to get to. I ran the harness over the transmission shifter linkage to keep it hidden, plugged into the brake controller, then hid those wires to not be seen when door is open or sitting in truck, I don't like loose exposed wires.



- C51332
by:

Could be more Happy, Once I found the plug for the adapter cord, which by the way is on the upper LEFT side of the fire wall near the parking brake pedal, it took less than a minute to snap it in and then drill the hanger for the controller. Whole process took about ten minutes. Thanks for making it so easy.

by:

This is the second curt controller and wire harness I have ordered from etrailer, among other items in the past. Shipping is second to none and I received items very quickly. My needs for towing parts and items will always be thru etrailer.



- C51332
by:

Direct plug-n-play. No modification necessary just like they say. Other than the two mounting screws of course. Whole process took 5 minutes and three of those were dealing with a tangled extension cord. Oh and the product came much quicker than expected which is the norm for etrailer. Thanks again for another awesome experience!!



- C51332
by:

Product was exactly what was ordered, installation time was about 15 minutes from start to finish. This item performed as stated in product description, delivery was 2 days quicker than expected. Would use etrailer again for my towing needs. Thanks Ron T.

Received my brake controller and cord in 4 days and everything seems to be working perfectly. This is the second time I have ordered from etrailer with excellent results.

  • Where is Brake Controller Adapter Plug Located In 2002 Dodge Ram Pickup
    The green connector in your truck is not the correct plug. It is normally a blue plug like what I have shown in the photo that plugs into the adapter part # C51332 if you are using a Curt brake controller like part # C51170. There will be a port to plug into if the truck came with a factory 7-way plug just to the right of the emergency brake. If the 7-way plug was installed after-market, you will need to see how far the wires from the plug are extended so you can complete the install...

  • Curt Brake Controller Recommendation for 2005 Dodge Ram 2500
    The price for the Venturer controller part # C51110 and install harness part # C51332 is tough to beat but a proportional brake controller will be a much better option. Proportional controllers sense how hard you are applying the brakes and apply the trailer brakes the same way. Time-delayed like the Venturer put out a preset amount of braking power so they aren't as effective. So instead the Triflex part # C51140 with the install harness # C51332 would be the better option for your...

You will need a circuit tester like the # PTW2993 to test wiring functions under the dash, and you may need some butt connectors like the # DW05745-5 to complete your wiring connections....

    You are thinking of Tekonsha brake controllers. They are pretty much the leader in the brake controller industry. The Curt controllers would not be my first choice.

    Brake controllers such as # C51110 will have constant power once installed. They need to have constant power otherwise they would reset every time you turned off the vehicle. Brake controllers have what is basically a sleep mode. After a certain amount of time the "go to sleep" and draw only a few milliamps of power so they will not drain the vehicle battery.

    I do have an option for you but unfortunately we would not have access to the wiring diagram for a 1997 Dodge Ram 1500.
