In-Line Circuit Breaker - 20 Amp - Perpendicular Mount Bracket - 9506P

Average Customer Rating:  4.9 out of 5 stars   (86 Customer Reviews)


Ordered two curt venturer brake controllers,after calling a local trailer shop that wanted $370-$400 dollars to install them I figured I'd do it myself. After watching videos from etrailer and youtube I installed one in my 2003 Ford Ranger and one in my wife's 2101 Town and Country. Everything was pretty much straight forward, just take your time and follow the video's. Very happy and saved hundred's by doing it myself. Here are some pictures of the two vehicles.


Perfect connector for what I was looking for on my 2019 RAV4. I originally installed it with the L bracket, but later changed it to be flush in the bumper. Looks very clean. The prefab pigtail made install into the car very easy as well.


Needed for my installation. etrailer staff was very helpful in helping me order all the pieces that I needed.


Easy to install. Copper terminal goes to battery. FYI


Excellent quality and strength. Why skimp on something as important as your hitch? I have purchased three of these Draw Tites - I guess a repeat customer will scream about the true quality a company can garner from repeat customers. When you pull show cars worth six figures, you can't afford a poorly made hitch.
Step up, step out, and don't fret what you are pulling.


Ordered a brake controller and an inline circuit breaker. Very happy with both but not the shipping. I selected the least expensive (my bad) shipping because I didn't need it for a few days. I opted for the UPS/US Mail combination shipping, what ever that is. Product shipped same day as I ordered it (Feb 11th) with an expected delivery date of Feb. 15th. Finally showed up on the 20th. I ordered a hitch earlier and in 2 days I had it. A 49lb hitch vs. a pound (maybe) package. Not etrailers fault...but I can see why the post office is going broke with service like that!


Bought several trailer products for our 2013 Explorer, Tekonsha trailer brake, trailer hitch & wiring materials. Excellent fit on the trailer hitch. Shipping timely & well packaged.


Installed the Hopkins InSight brake controller in a 2015 Wrangler Unlimited. Installation was straightforward with no problems. The biggest plus with this unit is the ability to mount the "brain" out of sight and mount the display and the manual control in separate, convenient locations. Very nice. Also ordered a 20A breaker, extra wire and an extra harness connector (for another vehicle). All items arrived on time and well packaged. etrailer gets a big thumbs up!


Met my expectations, good installation instructions and performed well throughout the summer and fall of 2017.


Just what the etrailer video showed to add a Tekonsha Primus IQ trailer brake controller to a Chevy Silverado. ( I could have used a bracket as well ). Super fast shipping!


I ordered everything I needed for wiring and towing with my new vehicle. As in the past, etrailer promptly shipped all that I ordered. A very reliable and helpful company to deal with. UPS was a little less than gentle with the package but the driver waited while I determined that nothing had fallen out of the holes in the box.


Exactly as described and does the job


All parts ordered from retailer have been excellent quality.


Works great. You definitely want to use this and not a fuse for a trailer brake controller. If an intermittent short blows a fuse, you will lose your trailer brakes. This circuit brakes auto resets so your trailer brakes won't be lost.




Great service and delivery


Easy to install (two screws to mount it and two nuts for the wire connectors), well labeled for which wire goes where, and works well. Much nice than a fuse, and essential when protecting a trailer brake circuit!


Products as described. Excellent quality. Fast ship.


Perfect little circuit breaker for 12 volt supply to trailer fridge!


With the good instructions the cb works good .

Working great
James C - 01/05/2018


Looks good and simple to install.


Little details make the differenc!I bought this product for future (1 month) installation in an used van that I purchased. I received the product in a fantastically short period of time. I am very impressed with the quality of the workmanship and materials.


Easy installation and works as expected


Didn't need the post, fuse box on the truck already had them. Everything else worked fine.


Great service, and research given with the representative to order the correct parts needed. I am a returning customer for this reason and will again in the future.

  • Does Circuit Breaker # 9506P Have to Install in a Certain Direction
    Circuit breakers can have current run through them in either direction. The # 9506P just needs be wired between the battery and the 12 volt power circuit of your brake controller. The basically you would run from the black wire on your controller to the breaker and then to the battery post.

  • Can a 20 Amp In-Line Circuit Breaker be Installed Under the Dash of a 2002 Mazda Protege
    Yes, you can install the in-line 20 amp circuit breaker, # 9506P, pretty much anywhere on any vehicle including your 2002 Mazda Protege and including under the dash. I have included a link to a video that, in part, shows this circuit breaker being installed.

  • Amperage of Factory Brake Controller Pigtail on 2005 Dodge Ram
    We have never come across this 15 amp maximum. Take a look to see how that 12V feed is fused. I would consult the owners manual to find the location of the fuses that manage the towing circuits on your truck. They are usually located under the hood. Usually the 12v power feed for the brake controller has a 20 amp fuse for a 2 axle application. If you are concerned about it, you can always run a separate hot lead via a 20 amp circuit breaker like part # 9506 to the battery. For a two axle...

  • Brake Controller Installation on a 2001 Chevy Express 1500 with 7 way plug
    The blue wire you found will need to be run to the blue wire of the Tekonsha P2 Brake Controller part # 90885 that you referenced. If you need a 12 volt accessory circuit on your trailer connector you will need to connect that red wire to your positive battery post. I am not sure what the white wire is for, but you could trace it back to see where it terminates on your 7-way and compare it to the diagram I attached to see what its function is. Since it is white there is a good chance it...

  • Using Inline Fuse or # 9506P 20 Amp Breaker To Install Brake Controller On 2014 Grand Caravan
    You can indeed use an inline fuse holder, but the # 16167-1 fuse holder you mention is meant for 14-16 gauge. If you can find an inline fuse holder that uses 10 gauge wire, that would be fine. The # 9506P circuit breaker does not need to be fastened to the sheet metal using screws, as no ground is needed. You could use zip ties or even double sided tape, if needed. I've linked you to install details as well as an install video showing a brake controller being installed on a Grand Caravan...

  • Wiring The Blue wire on 4-pole to 5-pole Adapter
    The blue wire on the Trailer Wiring Adapter 4-pole to 5-pole is normally used for boat trailer connections where the trailer surge brakes need to be locked out. The blue wire is connected to the vehicles backup light circuit so that when the vehicle is shifted into reverse the surge brake coupler will not activate the trailer brakes when backing up. This adapter, blue wire included, is meant to be connected at all times when towing the trailer. The blue wire could be connected to another...

  • Wiring and Installing an Electric Brake Controller on a 1986 P30 Chassis Motorhome
    Brake controllers are not vehicle specific items so there are not diagrams available for individual vehicles. We do have a help page on installing brake controllers that will walk you through the process, but I will briefly run through the process to give you an idea of what has to be done. Most brake controllers have 4-Wires, typically they are: blue, black, red and white. The white wire is a ground, so it needs to be connected to any solid ground point. The red wire is the stop light...

  • Troubleshooting Trailer Bake and Turn Signals Not Working on Trailer Towed by 2003 Ford F-250
    A pulse preventer would be needed if when towing with the hazards on, the display on the brake controller also flashes. This could then potentially be felt in the trailer brakes if the brake controller is set to a high level. It would not help with the turn signal and brake light problem. In situations like this, its best to start with the easiest possible solutions. First, I recommend cleaning the connectors on both the truck and the trailer. Any dirt or corrosion could cause a problem....

  • What Amperage Circuit Breaker Should be Used for Brake Controller Install
    That will depend on the amount of brake axles your trailer has. . The 20 amp breaker like # 9506P is for 1 and 2 axle brakes, and the 30 amp like part # 38630 is for 3 and 4 axle brakes

    It sounds like maybe your controller isn't applying the brakes if the .c is showing when pressing the brake pedal. You will want to check to be sure you are tapped into the correct brake light wire. This is the wire that is only hot when the brake pedal is pressed. You will also want to make sure you installed the correct circuit breaker per the number of brake applications on your trailer. 20-Amp circuit breaker # 9506P for 2- to 4-brake applications and 30-Amp circuit breaker # 38630...

  • Recommended Circuit Breaker to Use In-Line with Battery Isolation Solenoid for Switched Lights
    Tow Ready Battery Isolation Solenoid # TR118665 is not circuit breaker protected so the power running in and out of it will be different for each vehicle. I recommend using a circuit breaker like the In-Line Circuit Breaker - 20 Amp - Perpendicular Mount Bracket # 9506P to protect your switch and light. This has an automatic reset when over-current is removed and cycles continuously during over-current condition to protect your accessories.

  • Troubleshooting Brake Controller Installation On 2013 Ford Escape
    It sounds like there are some wires installed incorrectly. When connecting the red wire to the stop light switch on your Escape, it should be attached to the purple/white wire. There is another purple wire but it has orange and is not the correct wire for the brake controller. You can also use a circuit tester like part # 40376 to check the wires for function. Then run the 12 V black wire to the positive battery post using a 20 amp circuit breaker like part # 9506P. The blue wire runs...

  • Dim Display When Installing Tekonsha Prodigy On 1999 Dodge Van
    I spoke with my contact at Tekonsha about your 1999 Dodge van and the Tekonsha Prodigy Brake controller. They told me that if you are having a problem with a display being dim, you may have an issue with the ground wire connection. You want to make certain you have a good ground connection or it can cause issues with the display and function of the controller.

  • Installation of the Prodigy On a 96 Winnebago p-30 chev.
    Installation of the Tekonsha Prodigy should be fairly easy with the Winnebago having a 7 -way connector installed from the factory. There should be a wiring harness under the drivers side dash that will have at least 4 wires to connect to the brake controller. I do not have vehicle specific information on the Winnebago wiring location but it should be there if it was a factory option. The wires should provide brake controller functions. If you have a GM chassis then the colors of the wires...

    The wires for the brake output and the 12Volt accessory lead terminate in the engine compartment. They are located under the brake booster, down where the brake lines turn to pass under the cab. They are bundled together and are wrapped in electrical tape, and can be challenging to find. The orange wire would need to be run to the positive battery terminal via a 40 amp.

  • Cirucit Breaker Ratings for Installing Brake Controller on 2006 Toyota RAV4
    When installing a brake controller on a vehicle that is not factory wired, we typically use a 40 amp inline circuit breaker (part # 9510) to protect the 12 Volt accessory circuit that runs from the battery to the trailer connector. The power supply circuit for the brake controller itself is protected by either a 20 or a 30 amp inline circuit breaker (part # 9506P, # 38630). The installation instructions for your brake controller will state which breaker is needed. I suppose the other setup...

    The blue wire should be run directly to the trailer connector. This circuit should continue on to the brake magnets. Each magnet should have two wire leads. One of these leads should be connected to the brake controller output circuit. The other should be grounded to the trailer frame. The black brake controller wire should be wired directly to the positive terminal on the battery with a circuit breaker in-line to protect the brake controller. If you have a 1-2 axles with brakes you should...

  • Where to Install Prodigy P-2 Brake Controller # 90885 on a 2010 Mercedes GL450
    We do not have vehicle specific information for installing the # 90885 brake controller on your 2010 GL450, but as a general rule you will need to be able to mount the unit in an easily accessible location. Usually the brake controller is mounted near the driver's right or left knee, so that you would have access to the emergency brake function if needed. Since no custom wiring is available for your vehicle, you would need to hardwire to install the brake controller. The unit includes...

  • Is a Cover Necessary to Protect Circuit Breakers Once Installed on a 2001 Toyota Land Cruiser
    The circuit breakers do not need to be covered, as they should be mounted in an unobtrusive area under the hood of your 2001 Toyota Land Cruiser, typically on the back wall below the windshield, or inside the driver side fender, near the vehicle battery. No snap on cover is available. If you choose, you could probably put some cap nuts on the exposed posts on the circuit breakers, but if there does seem to be some risk that the posts on the breakers would come into contact with anything,...

  • Dimensions of Straight Mount and Perpendicular Mount Pollak 20 Amp Circuit Breakers
    Both the # PK54520 Straight Mount and # 9506P Perpendicular Mount Pollak 20 amp circuit breaker are 11/16" long. They have a distance of 1-9/16"center to center for the mounting holes, so as long as you have that amount of space you would be able to mount either breaker.
