## Questions & Answers

**Q: Can you press the button and force the brakes on?**
A: Yes. This is required in the event the trailer swaying or jackknifing out of control. The theory is you push the button and it pulls back on your rig this straightening it out to regain control. Not sure we would be quick to remove our hands from the wheel but DOT prefers that the trailer can be controlled separately. This requires the control in an unobstructed location.

**Q: Is it dimmable? Also do the lights on it come on if there is no trailer hooked up?**
A: Yes, the lights on the controller are dimmable, but at the lowest setting they’re still pretty bright. It does flash green lights when you first start up and that lets you know you’re not connected to a trailer. When you brake without a trailer connected, it has a blue light that will come on. Still fairly bright. I put a layer of “Sharpie” over the lights to dim them somewhat more as I mounted my controller where I can see it easily and adjust it if need be. Seems to work well.

**Q: How long is the cable from the control knob to the module**
A: 48 inches....(four feet long)

**Q: Is it compatible with curt 55567 vehicle-side custom 4-pin trailer wiring harness for select mazda 3, 6, toyota camry, fj cruiser ?**
A: The 51170 is a trailer brake controller while the 55567 is a 4 pin connector for trailer lights only (not brakes).  If you have trailer brakes you need a different wiring set up than the 4-pin harness. If you don't have trailer brakes you don't need the 51170 controller

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by F***E on July 30, 2025*

Very easy to install and worked great

### ⭐⭐⭐⭐⭐ Best controller out there!
*by E***L on May 14, 2025*

Best controller I've used in the last 30 years. I've owned allot of brake controllers from every price point out there and this is the best. I set it up the first time, tweaked it once and haven't touched it in almost a thousand miles. No fiddling trying to get a better stop or working out the lurches of the trailer stopping you. I can ease to a stop or punch the brakes hard, and I get the right amount of braking every time without adjusting it again. It looks OEM in the truck and the brightness is plenty adjustable, this coming from someone who will turn his dash lights off to avoid distraction. It does it's thing and I just drive.

### ⭐⭐⭐⭐⭐ Great product and looks factory on my 2008 Silverado
*by B***D on February 16, 2021*

I was looking for a brake controller that didnt get in the way of my knees, old style brake controllers always annoyed me and just plain look bad, so when i found out about this brake controller from curt that only shows a remote knob, i figured i would try it, it is very expensive compared to other brake controllers, but its kinda a specialty for people like me who dont like normal brake controllers, so i was willing to spend the money, first off ill say everyone that had problems with the controller flashing when not in use almost made me not buy it, but i figured i would wire a on/off switch if i had that problem but it never happened to mine, I havent actually hauled a trailer yet, but i did connect to one just to see what happens, nothing different than when not connected, except when i unplugged the trailer i did get the flashing blue lights which mean the trailer was disconnected, those lasted about 10 seconds and then it returned to the normal mode, for my fellow 07-13 silverado owners thinking about buying this, just make sure you order the wiring harness adapter, its like $8 you wire it up to your trucks already pre existing brake controller wires under the dash and then it plugs directly into the module that comes with the brake controller, and then connect the 2 wires to the fuse box under the dash, they are already there from the factory, google should make all that easy, but overrall its super simple to install and super easy to use, i should be hauling a trailer soon, if this is the last you hear from me about this brake controller it means it worked great, if it does not work great i will be back to change my review
