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.

It does not fit my vehicle. On the attached photo the connector on the left is the stock dodge plug, the plug on the right is what I just got

Hmm...youll be looking for another white plug like the white harness. Do you know if your truck for sure has the factory tow package?

2008 Dodge Ram Pickup

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 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.

2007 Dodge Ram Pickup

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.


The folks at etrailer are the best! Very helpful and knowledgeable!! The product I received fit perfectly and works great!!



Still working great!

1999 Dodge Ram Pickup

Perfect fit for my 1999 Dodge Ram. it made installation of the brake controller super easy. I highly recommend paying the extra $** for this item.


y0u want good go to etrailer was a perfect fit


I ordered a fifth wheel brackets and hitch along with curt brake controller and pigtail. Everything fit great with no problems and the service and shipping was very speedy. Highly recommend etrailer for all your needs.

Dodge Ram Pickup

2006 Dodge Ram. Easy install. Plug it in and tie up the wires. I put a wire protector sleeve to cover the wires coming out of the controller.


fit and finish was perfect.


Trailer control shipped quickly, super easy install with the pigtail. Happy customer!

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!

Jeff M.


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


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.

Michael D.


Still working fine.

Dodge Ram Pickup

The directions on this item are horrible. I finally figured it out and was able to install it onto my Ram 1500, but only after spending hours trying to make everything fit right. If you're looking for a hitch setup to pull a trailer long distances, I would advise you to look at other options. This will work for my short trips with my half-ton pickup, but I would not want to pull anything more than 50 miles with this setup.


Fast Shipping! Works great! Easy to ins tall!!


Used in conjunction with the Curt brake controller I purchased from etrailer.
Worked perfectly.

Larry W.


Works fine No reliability issues, worry free.


Worked great performance as described

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 the Curt TriFlex trailer brake controller. Had to return the first one, due to the manual brake activation lever being sloppy loose. They replaced it with no hassle. It looks cheap but works good so far

Land Rover Discovery II

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.

2008 Dodge Ram Pickup

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


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.

Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In - C51332
Item fit exactly and directions was very specific as to where to plug in in. Items were shipped promptly and was as described.

2007 Dodge Ram Pickup

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

2010 Dodge Ram Pickup

Great product and great service from 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.

  • Brake Controller for 2008 Dodge Durango with Factory Wiring Harness for Tow Package
    You need to purchase both the Curt Brake Controller # C51170 and the Curt Wiring Harness # C51332 for your Dodge Durango as they are sold separately. This allows you to plug directly into the port that comes with the tow package and is located directly under your dash.

  • Parts Needed To Install Brake Controller on 2005 Dodge Ram 1500
    Since your 2005 Dodge Ram has the factory installed 7-Way, to install a brake controller you will just need the brake controller itself and the proper wiring harness to plug it into your Ram. If you go with the Curt Venturer, # C74VV, the only other part you will need is wiring harness # C51332. I have included a link to the installation details for you. The wiring harness plugs into a connector already on your vehicle. The connector is located underneath the dash, to the left of the...

  • Best Brake Controller For 2005 Dodge Ram 3500 With Bumper Pull Camper
    First off, the proportional brake controllers are definitely recommended for a situation like this. They provide better response so they are safer, and also have less wear and tear on your trailer's brakes since they apply braking pressure equal to your vehicle's braking. For your 2005 Ram 3500, I recommend the Curt TriFlex # C24VV with adapter # C51332. Curt is a very trustworthy and reliable brand, and this controller is one of the most reliable controllers on the market. It is good for...

  • Quality Trailer Brake Control for a 2006 Dodge Durango
    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. I prefer Tekonsha controllers because they have a long proven track record of quality and performance. The Curt controllers are a less expensive option but they are new to the brake controller industry. They did have some performance issues initially but they are improving. I recommend the Tekonsha P2, # 90885. This is a proportional...

  • Do Brake Controllers have Constant Power or Do they Wire Into a Ignition/Accessory Power Source
    Brake controllers such as # C74VV 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.

    The Curt Assure Trailer Brake Controller with Dynamic Screen # C49UR will require a Curt Custom Wiring Adapter # C51332 to connect to your 2009 Dodge Ram 3500 that has a factory plug in connector. Another option is to use a Curt Wiring Adapter for Cequent Trailer Brake Controller Wiring Harnesses # C51520 to adapt the Tekonsha harness to plug into the curt. This will work best if your harness is difficult to get to or your wiring is hardwired and you do not want to have to remake the connections...

    The green connector in your truck is not the correct plug.

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.

  • Curt Spectrum Brake Controller Showing no Trailer on 2000 Dodge Ram 2500 After Replacing Connectors
    Yes, you are definitely on the right track. If your Curt Spectrum Trailer Brake Controller # C51170 is still not showing a trailer is connected and you have already replaced the connectors, I think it has to be a short either on the brake wiring or the brake magnets themselves. Before replacing your brake assemblies entirely, start by just checking the wires to the brake magnets (if you have not done so yet) and look for wires that may be pinched or otherwise damaged and fix as necessary....

  • Curt Brake Controller Recommendation for 2005 Dodge Ram 2500
    The price for the Venturer controller part # C74VV 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 # C24VV with the install harness # C51332 would be the better option for your 2005...

  • What Is The Blue Connector For In The Glove Box Of The Ram 2500
    I will be happy to explain how why the blue plug would not be installed in the wiring bundle. The blue plug is an adapter that's used to install an after-market brake controller. When installing a brake controller vehicles sometimes already have a plug and play connection under the dash. A plug and play connection is a connection that does not require the brake controller to be hardwired to the vehicle. Some brake controllers like # 90195 will need a plug or adapter like you have the #...
