Video Transcript for Dexter Brake Controller 58-8 Review

Today we're going to be taking a look at part number 58-8. This is the Dexter Axle Predator Electric Brake Controller. It's going to come with your mounting bracket and a mounting hardware as well as some detailed installation instructions. This is inertia activated, so the trailer brakes will apply in direct proportion to the total vehicle braking effort. The unit itself is going to control the power output to the brakes of the trailer and it's going to be able to control the braking response from the tow vehicle to the trailer as well. It's also going to help when it comes to setting the controls.

It's going to allow for manual application of brakes with the manual override lever here at the front. This unit is made for up to two-axle trailer brake systems which would be a total of four brakes. It's going to feature a large digital LED display. It's going to display the voltage output and it's going to make leveling quick and easy. The controller display will increase numerically during a stop or when the brakes are applied or more pressure is applied on the brake pedal. Then it's going to decrease or return to the minimum reading when deceleration is no longer detected.

When the tow vehicle brake pedal is completely released, the display will go off, kind of just as it's shown here. You won't be able to read anything on the display when the brake pedal's released. Again, the mounting bracket and hardware is included. This features a versatile mounting range of minus 35 degrees to positive 90 degrees to accommodate a wide variety of vehicle interiors. When it comes to the dimensions of the actual brake controller, it's going to give us an overall width of about 3 inches, an overall length of about 6-1/2 inches, and an overall height of 1-5/8. On this side, you're going to notice this little lever arm here.

This is the deceleration sensor level arm. When the tow vehicle decelerates, the sensor is going to send an electrical signal for the controller to increase amperage to the trailer brakes. This arm is simply going to allow you to set the level of intensity of that signal. Here at the front you're going to have the power adjustment wheel. This is used to adjust the amount of current or power that is sent to the trailer brakes from the tow vehicle. Then, you also have the manual slide lever.

This is used to apply the trailer brakes independently of the tow vehicle brakes, or to override the automatic trailer brakes. Here at the back it's going to expose four wires. Your white wire's going to be your ground. Your blue wire is for the trailer brakes. The red is for the stoplight wire that connects to the non-powered wire of the stoplight switch, or tow package harness. Then your black wire is going to be your power wire. Real quick, I just want to go ahead and connect this to our external power supply. That way you can see the LED display. You can get a good understanding of how bright that is and how easy it'll be to see. So you can see there the reading. That's when we apply our brakes. Then, again, as you press down the brake pedal that number will increase and then as you decelerate the number will go back down to the setting or the minimum reading. Then, when we do the manual override the display's going to come on as well and then when we fully release it, it'll go back to not reading anything. That's going to do it for today's review of part number 58-8. This is the Dexter Axle Predator Electric Brake Controller. .

Dexter Axle Predator Electric Brake Controller - 58-8

Average Customer Rating:  4.7 out of 5 stars   (6 Customer Reviews)



- 58-8

by: Bob J.09/07/2016


I am very satisfied with the Dexter Axle Predator Electric Brake controller. I purchased the Dexter brake controller to be compatible with Dexter car trailer axles on a 16 foot car hauler. The braking unit is very useful when towing in very steep and winding mountain terrain. I feel that the braking is a necessary safety item when towing in a hilly or mountainous environment and the Dexter Predator brake controller provides the great control and driver peace of mind knowing that a heavy load can be managed. The unit installs very easily with the proper adapter. 292121

Just finish installing the brake controller so I have not seen it in operation. Everything that was needed for installation was contained in the package. Due to limited access due to the chosen mounting location getting two of the side screws started took some effort. 199608

Ask the Experts about this Dexter Brake Controller
Do you have a question about this Brake Controller?


  • Location of Brake Controller Connector on 2012 Ram Truck
  • The connector you are looking for will be located taped to another larger wiring harness just to the right and above the emergency brake pedal, as shown in the photo I have edited for you. You can confirm that this is the correct connector by testing it with a circuit tester like part # 40376. One pin should show a constant 12-volt power supply, another should show voltage only when the brake pedal is pressed. Unfortunately, my contact at Tekonsha was not able to shed any light on...

  • Wiring a Dexter Predator Brake Controller, Part # 58-8, in a 2005 Ford F150
  • If your 2005 Ford F-150 has only 4 wires at the bumper (or only a 4-pole connector) and you need to install a 7-way vehicle-side connector, you could use the Hopkins # 37185. If you already have the 7-way connector on your truck, you will need to make the additional wire connections for the brake controller. (The 4 wires you have carry the brake light, running light and turn light signals for your trailer, plus a ground: white = ground, brown = running/brake lights, green = right turn...

  • Trailer Brake Controller Recommendation for a 2014 Chevy Silverado 1500
  • If you are concerned there is no where to mount a brake controller (something that comes up a lot since truck interiors are more and more car-like) then I have the perfect solution for you. You can use the Hopkins InSIGHT # HM47297. But you will also need wiring harness # 3016. You will need to cut off the end that plugs into the controller on the harness and the end of the plug on the controller box and splice the wire color for color. The other end of the harness will plug into the...

  • Wiring a Brake Controller on 2010 Chevy Silverado
  • You are correct, the tow package wiring in your Silverado does not match up color for color with the controller. The red/black tow package wire will connect to the black wire on the controller. The dark blue tow package wire connects to the blue wire on the controller, the light blue tow package wire connects to the red controller wire, and the white tow package wire connects to the white wire on the controller. The orange tow package wire is for an illumination circuit and is NOT needed....

  • Parts Needed To Tow a Towmaster Trailer with Electric Brakes with a Winnebago
  • The Dexter Predator brake controller # 58-8 would be a good fit to power the trailer brakes on your Towmaster trailer. You would need to hard wire the brake controller to the Winnebago, connecting the wires coming from the back side of the brake controller as follows. The brake controller wire functions are: White: Ground, attached to a clean piece of unpainted metal. Black: 12v lead, attached to the positive battery terminal on the Winnebago with a 40amp circuit breaker. Blue:...

  • Brake Controller Installation on 2006 Ford F150
  • The brake controller installation on your 2006 F150 is pretty easy. The connector for the brake controller is located under the dash, behind and to the right of the OBD port as shown in the video I've linked for you. You'll need the brake controller wiring adapter, part # 3035-S. The adapter will plug into the connector, and the bare wires on the connector would wire to your Dexter Predator brake controller, color for color. If your vehicle is equipped with the 7-way trailer connector,...

  • Brake Controller Recommendation and Installation on a 2003 GMC Sierra with or without Factory 7-Way
  • I did a little research and found that the Dexter Predator, # 58-8, is for 2 to 4 brakes. So if each wheel on your two axle trailer has a brake assembly, or just two of them, this brake controller will work. Brake controllers are not vehicle or trailer specific, so you will be able to use the best one for your application. I recommend going with a proportional controller because they offer the best and safest braking, and will reduce wear on both the trailer and tow vehicle brakes. I...

  • Brake Controller for Towing a Trailmaster Trailer with a Harley Electra Glide Classic Motorcycle
  • I have spoken with small tent trailer manufacturers about which brake controllers are best for their trailers with brakes and found that they recommend using a a time delayed brake controller for their trailers. They said that many of their customers have excellent performance from the Activator electric trailer brake controller by Draw-Tite, # 5100. The advantage of a time delayed brake controller on a motorcycle is that it can be positioned in any way, so you can easily find a mounting...

  • Trailer Brakes Lock Up When Brake Pedal is Pressed Even With Controller Turned All the Way Down
  • Have you tried towing the trailer with another truck? Or towing another trailer with the Dodge? This would help you narrow down whether the problem is with the wiring on the vehicle or the trailer. From what you're describing, it sounds like either something's incorrectly wired on the vehicle or trailer, or the trailer connector on the vehicle is damaged or corroded. This is kind of a strange occurrence, so try what I've mentioned above and get back with me. I've also linked you...

  • Surge Brakes or Electric Brake Controller for a Trailer Towed by a Motorcycle
  • Electric brakes and brake controllers do require adjustment when the trailer changes weight due to adding or removing a load. As long as you remember to do that there is no problem with the brakes being too aggressive. Surge brakes require a certain amount of momentum, inertia to activate the trailer brakes. The reason you do not see them on trailers towed by motorcycles is because those trailers are light and it does take a lot of pressure to activate the brakes that just isn't present...

  • Troubleshooting Brake Controller that Won't Work with Brake Pedal
  • If a brake controller is detecting a trailer connected when there isn't one connected that indicates that there is a load somewhere on the brake output circuit that is confusing the controller. Typically this is corrosion on the 7-way and cleaning the pins with fine grit sandpaper will do the trick. If a controller will work with the override but not with the brake pedal that indicates a problem with the red (stoplight circuit) wire of the controller. What you will need to do is check...

  • Can the Predator DX2 Brake Controller Work on a Trailer with 6 Brake Assemblies
  • I have a solution for you, but the Dexter Axle Predator Electric Brake Controller # 58-8 that you referenced can only be used on up to 4 brake assemblies. Instead you would want the Prodigy P2 Brake Controller part # 90885. This controller can be used on up to 8 brake assemblies and would work great for you. This is our best selling controller because of how easy it is to set up and how well it works.

  • Brake Controller for 1999 Chevy Tahoe Towing a 2006 Fleetwood Bayside Camper with Electric Brakes
  • Since brake controllers are not vehicle-specific, you can use any of our brake controllers with your 1999 Chevy Tahoe and 2006 Fleetwood Bayside camper. The Dexter Axle Predator Electric Brake Controller, part # 58-8, is a great choice. It is inertia-activated, meaning you have a lot of mounting options for inside your Tahoe, has an LED display showing voltage output, and works with 1 or 2 axles. If you don't already have a 4-way connector on the back of your vehicle, you will need the...

  • Hazard Lights Locking Up Trailer Brakes and Activating Electric Brake Controller On RV
  • If the red wire from your brake controller is tapped into a wire that has voltage when the hazard lights are activated then this situation will occur. You will need to attach the red wire from the brake controller to a brake signal wire, under the dash at the brake pedal switch, that only has power when the brake pedal is pressed on your RV, so that when the hazards are on your trailer brakes do not lock up.

  • The light blue wire mentioned in the video of the # HM40975-11998 7 and 4-pole trailer connector being installed on a 2002 Silverado is for a camper shell brake light, and is not for use with an electric brake controller. The electric brake wire on your 2001 GMC Sierra is run from the port below the dash into the engine compartment, but it does not continue back to the rear wiring bundle. You will need to finish the connection by running a wire from the 7-Way in the rear of the truck...

  • In my research, the 2013 Chrysler Town and Country with a tow package does come with a wiring harness and should have a 7-way. To install the Dexter Predator # 58-8, you will need to run the wires from the brake controller to the 7-way connector on your vehicle. You are also going to need Draw-Tite # 5506 which gives you the extra length you will need to hook up your brake controller to your 7-way connector.

Black: 12v power wire, connected to the vehicle positive battery terminal with a 40amp circuit breaker, part # 9510. Red: Stoplight switch circuit. This will get run to the wire on your stoplight pedal assembly that sees voltage only when the brakes are applied....

  • Trailer Brake Controller for a 2008 Saab 9-7X with Factory 7-Way Trailer Connector
  • The 24 pin receptacle you are seeing sounds like the OBD2 port and would not be used for a brake controller. You will need to utilize the owners manual or a Saab technician to locate the wires and to determine the functions of those wires. Identifying the wire functions is critical because a brake controller has to be hardwired in since there is no plug and play option available. The wires on a brake controller are as follows: white is ground black is 12 volt power in blue is output...

The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. I have included a link to a video that should help. For the Dexter brake controller, # 58-8 you referenced, you would need wiring harness # 3020-P. To wire in your 7-Way that you have you will need to hardwire...

The vehicle manufacturer installs fuses to protect the OEM electrical components in the vehicle so any aftermarket accessory that is added will need to be protected independently of the factory fuses and circuit breakers.

  • Brake Controller Does Not Have Full Power When Used
  • First, I would go to the 7-way connector and test to make sure you have power. You will want to use a circuit tester, part # 3808 to test the wires. Start by testing the Black wire for power, then test the Blue wire for brake controller output. To test the Blue wire you will need to have a friend help you. With the vehicle in power accessory mode, in park, and parking brake engaged, have them activate the brakes. Next I would check to make sure the Red Stoplight wire is connected and...

Dexter doesn't offer a harness that's compatible with your Ram, so I'd recommend a different controller. The Curt Reflex, part # C51130 would be a compatible controller that would work great for you. You'd also need the # C51453 wiring harness. If you click the provided link, you can see exactly where the...
