We have a small car. So our trailer is reasonably light, but the added control is great! The controller works seamlessly with our driving

I purchased the Curt Venturer trailer brake controller to install in my '06 Tundra to tow a 3,000 lb, single axle, travel trailer. The controller was easy to install and I used one of the Curt custom harnesses that plugged directly into the pigtail connector of the truck. No wiring work required; just plug and play.

This little controller does what it claims and will stop the trailer, and truck, depending on how it is set and the road surface. It is a great value. I only with wish it had a rotary adjuster for the brake power level. See next paragraph for why.

There are two sliding adjusters on this controller; (1) for the power level applied to the brakes and (1) for the delay time prior to brake application. There is very little resistance to moving the slide adjuster for brake power level and there is a wide range of power in a fairly short slide travel. Therefore, it requires some finesse to get the power level set where I like it for changing road surfaces; sand, gravel, and asphalt.

Other than taking care to make power level adjustments, I like the value and performance of this controller.

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.

When used with part number C51515, easy install, hardest part of install is deciding where to drill into your new vehicle's dash to mount controller, or just ask your wife :). The included test light makes finding the correct "cold" brake wire a breeze.

I have been very pleased with the products. The installation was easy and they work exactly as I had hoped. I will definitely purchase any towing products I need in the future from

Your company is awesome! I can’t write about the brake controller because my mechanic is putting it on today and it is the one he recommended. What I can write about is the customer service. You made ordering simple and the follow-up is fantastic. Delivery was quick and there were no delays. I will use your company again — and again. Thank you…

The CURT Venturer brake controller works as described in the user guide. It would be better if the display LED segments were bright enough to see in bright light. My installation is different from most. I mounted the brake controller and a trailer 7-pole socket to my Trailer Valet with a magnet and use the controller to operate the electric brakes on my trailer. This is far better than relying on the Trailer Valet brake alone, especially when moving the trailer on a grade.

by: DeannaG01/18/2023

It does the job for the price, but the slightest adjustment makes drastic changes in how my trailer brakes.

by: Tommy J.01/31/2014

With this brake controller and wiring harness installation was a snap in my 2014 Ford F150 STX. The unit is so light I used velcro to attach it to the dash rather then drill holes and use screws with the bracket provided. Easy to adjust the brake sync and braking force. Just a great product for the price.

by: Jose 08/14/2022

Great product work like it should. Don’t forget to Oder the pigtail for the brake controller if your installing it in an older pickup.

by: KENNY09/06/2016

I installed the Curt C51110 along with Plug & Play C51382 into my 2016 Frontier. The installation took me about 2 minutes. I did not drill holes or use the supplied mounting bracket, just Velcro. Works perfectly!

by: Steve T.06/18/2016

Super easy installation on my 99 Dodge Ram. I have only tested this item but I will be using it on a road trip soon. although I believe it will work perfectly. easy installation I recommend purchasing the wiring harness that plugs in under the dash. you can install this in about 10 minutes or less.

by: Roy01/19/2022

Very fast and easy installation

by: Glenn H.08/11/2018

Received product very fast. Everything I ordered was exactly what I got. Plug and play with what i ordered. It was hooked up with in less than 2 minutes then a couple minutes to screw in the bracket screws. Very pleased . I needed trailer brakes because I bought a camper and I did not want to wear out my truck brakes faster than normal. I looked around locally and on internet Etrailer had the best deal .

by: C Fisher10/11/2019

Straight forward installation. Works flawless. Simple and effective. Nearly impossible to find more bang for the buck. Used for hauling a twin axle trailer when loaded with my skid steet exceeds 13k lbs. Set the strength of the braking and rate of application with an emergency whammy switch. I have no reason to get anything else.

by: David03/09/2023

Not consistent always needs a little ad justment

by: G.01/04/2015

simplistic and it works for my purposes. Small form factor to fit to the left of the driver side dash.

For a time based controller its good for my single axle trailer. Eventually I will upgrade to the intertia based controller. Time based cant seem to find a happy medium with the brake intensity at various loads.

I strongly dislike this controller. I have had many trailers and brake controllers and I cannot get this one dialed in! I usually have to turn it completely off so it does not lock up my wheels. I will have to get a better controller next time I need to pull my rig.

by: RJ06/11/2014

Excellent site! Excellent information and How-To videos! Saved several hundred dollars installing myself. Free shipping was a bit slow, but that's expected. Will definitely recommend!

by: Dwight03/17/2023

I ordered thru etrailer twice. Both for brake controller and wire adaptor. Pleased with first shipment as it came fast and packaged well in its own individual package. My second order was fast as well,but the brake controller was in a damaged plastic box and looked like it was opened and crushed. Try to close it and wouldn't close. The wire harness was lose and just thrown in the box unlike my first order, which was in its own packaging as well. All in all I would purchase from etrailer again.

by: Stephen 09/14/2022

Good controller for the price.
I didn't
need a Cadillac version for the light towing in this vehicle.
Easy install.
Great service and delivery

by: Jason01/22/2021

It works, my only complaint is adjustment knobs move to easy so making adjustments you have to be really carefull

Adjustment takes some getting used to and is very touchy but once it is set it is a great controller.

by: Ted L10/13/2018

easy install, but extremely hard to adjust trailer load setting cannot stop trailer from over braking, very hard to drive in traffic. if this is not a defective I would not recommend it

The brake controller has two adjustments. You can adjust both the amount of power delivered to the brakes, and the speed at which that power is delivered. The synch control is located on the side of the controller, try decreasing the aggressiveness of the brakes a bit and see if that helps. Finding the perfect setting for the smoothest possible braking action could take some fiddling around with both the power and the speed adjustment.

No packing material what soever in shipping container. Contents were raddleing like nuts in a box. No physical damage on contents. Have yet to see if controller is functioning! Picture clarity of Sant Cruz dash plug location leaves a lot to be desired, Still trying to find under dash plug!

I do know that the plug is located on the drivers side of the steering column and is a cream colored 4 pin plug. It can be tricky to find. I also wanted to make sure that your 2023 Hyundai Santa does have the tow package included. If you are not sure you can contact the dealer with your VIN number to verify.

I purchased this controller to install in my daughter's 2013 Ford Explorer. It is the exact same model as the one I have in my 2010 Ford F150. The "slide" adjustment on this one does not have as much resistance to adjustment as my original so setting it is requires a very delicate touch. I would probably would have asked for a replacement but I did not have time to make an exchange as she needed to use it right away. However, it appears to be operating fine and did not move from it's position once it was set. I would have rated it as excellent except for this one weakness.

So far it has been working just fine!

I finally got a chance to hook up to a trailer. Everything works fine. I figured it would. I had bought a Curt controller years ago (2006?) And pulled many heavy trails with no worries.
I was dismayed by the packing. There was so little bubble wrap in the box that the controller bounced around so much in its clear plastic that contents of that clear box were spilled out into the shipping box. Room for improvement there.

The controller great!. Works perfectly on my 67 Chevy C10

Sent me a unit that was open, dirty, and had fingerprints on it. Obviously someone tried installing and it didn't work or was incorrect . There responce from the photos I sent were it is a new unit and opened from bouncing around in shipping, and they could tell that from the photos.
I replied send me a return label and crickets from them. I've purchased many items in the past totalling hundreds and hundreds of dollars. Never again if this is how they do business!

Thank you for bringing this to our attention and for reaching back out. I have sent your information to our customer service team and they will be in touch soon.

Received all contents in perfect condition, Ann E was great at her job. All the information for installation is included. And it only took about 8-10 minutes. Have not used it yet so hopefully everything will be terrific when i apply my brakes on my new ozark 1650 bkh RV.

by: Paul07/05/2018

This Curt Discover controller works great. Super easy to install if you get the pigtail for your model truck. I especially like the fact that you can install the bracket under the dash on my new 2018 Silverado using factory screw under the dash. No drilling required. As always wonderful pricing and delivery from E-Trailer.

by: William 03/02/2023

I am very happy with the Brake controll er.

by: Tacoma Stan09/11/2016

Fit nicely under the dash on the left side. Also installed a 7/4 pin connector in the bumper, replacing the blank plug from the factory(etrailer p/n HM40975-11998)

by: Paul03/11/2023

Would of gave a better rate if it had the harness or told me I needed a separate harness I really don't want to cut the connector off.

I do see that this does have plug in options where you dont have to cut off the connector. If you have the factory 7 way on your vehicle, you can use part # C51312

I bought a new car dolly with electric brakes to pull with our motorhome ( Fleetwood FlAIR 2001 ) as all states require brakes on trailers at all different weight levels. I called E trailer and spoke with Danna and after talking with her about different models I choose the C51120 time delay control, as it can be adjusted to work well with the tow vehicle . I received the control with in 3 days of the order and went to put it in and found under the dash wire a harness by Fleetwood which told where each wire on the controller went on the harness. I was able to hook it up sitting in the drivers seat. Completed the hook up and started to test the operation, to find I was not getting the proper readings. I talked with Tom and he said he would bench test a like control and report back to me, at 6 pm he left a message on our phone that he believed the problem was along the blue wire to the trailer on the tow vehicle . I started at the back of the, motorhome and moved forward testing for a brake signal, I found that the butt connector had pulled apart and was not getting current to the plug in at rear of coach. Hooked it back together and re taped the wires and it works like a charm. I want to thank all off you for the prompt and knowledgeable service, I would recommend E trailer to anyone who wants to deal with a great staff and company Thank you

I used this controller to pull ma car dolly to AZ and back through all the mountains and it worked GREAT I am very happy with how it worked Great product
