I ordered this controller and additional parts from Laser. Before committing to buying, I asked him many questions. He answered them all in about a clear and concise way as possible while presenting a picture of how to install the device. It arrived today and I haven't started, but he also emphasized that I could call if I ran into any difficulties. I'll follow up when the job is complete. My experience in this context could not have been better. Michael 696590

I followed the detailed instructions from etrailer’s video to add a 7pin trailer harness and ebrake controller for my 2010 Dodge Dakota Big Horn. I ordered the 30 amp and the 40 amp circuit breakers for the 12 volts and ebrake controller power supply. The order came in with a 30 amp and a 20 amp breakers instead. I contacted etrailer about the mistake and etrailer sent the correct 40 amp right away without hesitation. Etrailer has been a great source of information and they have the best customer service out there. Thank you!! 555546

  • Installing Wiring for Vehicle 12V Battery and Trailer Connection to Charge Trailer Battery
    The wire connected to your 12V (1 o'clock) position on your 7-way should be connected to a 40 circuit breaker like # 9510 and then to your vehicle's positive battery terminal using 10 gauge wire like # 10-1-1. The 12V power at your trailer connector is often connected directly to your trailer battery to provide a maintenance charge while you drive. This is a slow trickle charge based on your vehicle battery charge and your alternator. It is normally around 5-10 amps but this connection...

  • Availability of 40 amp 12 volt Circuit Breaker
    The breaker part number you mentioned is a 40 amp breaker like our part # 9510. You'd want to check with Tioga with the circuit you are referring to get the correct breaker for it.

  • Ford F-250 12v Circuit on 7 Way Trailer Connector is Not Powering Up Unless Truck Is Running
    If your 2016 F-250 has the "smart" tow connector, the 12 volt power circuit on the 7-way has to have the key on to activate. Because of the "smart" tow setup, you have to connect to a trailer and do a setup on the info setup that includes naming the trailer to allow it to be sensed and have the circuit activated when plugged in. In this case easiest solution is run a 10 gauge wire like part # 10-1-1 through a breaker part # 9510 from the 1:00 pin of the 7-way to the positive post of...

  • Where to Get Power Supply for the Auxiliary Connector
    To wire a 12V lead to your trailer connector, you will want to run the wire to the battery, via a 40 amp circuit breaker like part # 9510.

  • Recommendation for Charging Trailer Battery from Towing Vehicle
    You can connect your deep cycle AGM 75AH trailer battery directly to your 7-way 12V power for a small maintenance charge. This normally will only give you about 2-4 amps charge because your vehicle is needing the other amps produced from your alternator to maintain your vehicle functions. Only what is not used by the vehicle is available for the trailer battery. This also will not allow a full charge to your battery but will charge it up to about 80% just like a trickle charger, where...

  • Is a Fuse Needed on 12 Volt Power Circuit of Trailer Wiring
    If you are running a wire from the battery of your vehicle back to the 12 volt power circuit of a 7-way you will need to install a circuit breaker on the circuit like the part # 9510. The advantage a breaker has over a fuse is that it will automatically reset and won't require you to replace anything.

  • Does 40 amp In-Line Circuit Breaker 9510 Reset Itself if it Trips
    Circuit breaker # 9510 is self-resetting. If it trips due to an overload situation it will keep trying to cycle back on until the overload is resolved. So you won't have to replace it or do anything!

  • No Auxiliary Power On a 2015+ Ford F-Series Pickup
    I am not really sure what module that you are referring to but it sounds like you may have a 2015+ Ford Pickup. If that is the case then the 12 volt trailer battery charge circuit is not active on some 2015-2017 models when in park or during gear shifting so it would not be very easy to test this. If you have a 2018+ model then the 12 volt trailer battery charge circuit must first be activated via the in-dash screen. If you need help on doing this you can refer to the owner's manual. If...

  • How to Get 12V Power to 7-Way Trailer Connector on 2019 Ford F-250
    The power to the 12 volt pin on the 7-way of new Ford trucks like your 2019 Ford F-250 is unfortunately a common struggle so you're definitely not alone but thankfully there is a pretty simple solution. All you need to do is run your own 10 gauge wire # 10-1-1 (sold by the foot) from your 7-way through Circuit Breaker # 9510 and to the positive post of your truck battery. This will resolve the issue of you having to start your truck just to turn some lights on.

  • Recommended Circuit Breaker and Wire Gauge for Wiring 7-way Trailer Connector
    For a circuit breaker, I recommend using a 40 amp circuit breaker, like the Pollak 40amp In-Line Circuit Breaker # 9510. The wire that runs to the battery will connect to the gold post, and the line that connects to the junction box will connect to the silver post. Usually, 10 gauge wire is used for the 12V power. I recommend using # 10-1-1. This 10 gauge wire is sold by the foot. To make connections with this wire, you will want to use 12-10 gauge wire ring terminals # DW05705-1 or...

  • Does it Matter Where the 40 amp Circuit Breaker # 9510 is Mounted
    As long as the mounting location you choose for the 40 am Circuit Breaker # 9510 is in a safe area away from the elements and moving parts it would not matter if it got mounted to a frame or a rubber surface.

  • No Power To The 12 Volt Terminal On The 7-Way Vehicle End Connector of 2019 Ford F-150
    In regards to a 2019 Ford F-150, the 12 volt trailer battery charge circuit is not active on certain models when in park or during gear shifting. It is also not active until the trailer is plugged in. The 12 volt trailer battery charge circuit must first be activated via the in-dash screen on certain models as well. If you need help on doing this you can refer to the owner's manual. If the 12 volt trailer battery charge circuit is still not active after addressing the above then you...

  • Parts Needed to Add +12V Charge Wire to 7-Way on 2017 Subaru Outback
    All you need to add an active +12V power feed to your existing 7-way trailer socket is 10-gauge wire # 10-1-1, a 40-amp auto-reset circuit breaker # 9510 and ring terminals # 44-5310A. The breaker will install at the battery. Connect the copper-color terminal to the battery and the charge wire to the other terminal. You will want to keep the breaker's 40-amp capacity in mind as you apply a load on the trailer/output end to avoid tripping the breaker. If overloaded it will re-set once...

  • Recommended 12V Trailer Connector Wiring For Constant Power On 2015 Ford F150
    There is a very easy solution, but it means bypassing the Ford electronics. You can run a 10 gauge wire like # 10-1-1 directly from the battery, through a circuit breaker like the 40 amp In-Line Circuit Breaker - Perpendicular Mount Bracket # 9510, and directly into your 7-way trailer connector. This is the pin at the 1 o'clock position when looking directly at the connector from the front, so from the back of the connector it would be the 11 o'clock position.

  • Recommended Trailer Wiring To Charge Battery And Use Solar Panels
    To wire your vehicle battery 12V to charge a trailer battery, I recommend using a 40 amp In-Line Circuit Breaker - Perpendicular Mount Bracket # 9510 along with # 10-1-1 to wire your trailer connection. In order not to drain your vehicle battery, I recommend you use the Tow Ready Battery Isolation Solenoid # TR118665 to only allow the trailer to draw power when the vehicle is running. You will need to use an ignition-controlled circuit in your truck to activate the solenoid. The radio...

  • Brake Controller Wiring on a 2006 Nissan Pathfinder
    The blue wire coming from the 7 way at the rear would connect to the blue output wire coming from the brake controller. Typically this wire would run from the port under the dash to a location somewhere near the rear of the vehicle. Check the driver's side frame rail or behind the bumper for a blue wire that is not connected to anything. The black wire is for your 12V lead, and would run to a 12V power source via a 40 amp inline circuit breaker like part # 9510. The orange lead is either...

  • Wiring Pollak 40 amp Inline Circuit Breaker
    The wire from the power source, which is the battery in this case, will connect to the copper colored terminal labeled BAT. The run to the 7-way connector will connect to the silver terminal, labeled AUX. 12 gauge wire would be acceptable, but 10 gauge would allow for a greater amperage draw without overheating the wire.

  • Is TIPM on 2006 Dodge Ram Causing no Power to Brake Controller
    The TIPM on your 2006 Dodge could be the issue causing a lack of power, though the only way to know for sure is to take the truck to the dealer and have them inspect it. You do have another option, which is to bypass the TIPM by running your own 10 gauge wire # 10-1-1 from your 7-way's 12 volt pin to the positive post of your battery through Circuit Breaker # 9510.

  • Locating Brake Controller Power Fuse On a 2002 Chevy Silverado
    If your 2002 Chevrolet Silverado did not come wired with a 7-Way plug from the factory, you will need to connect the brake controller power wire and the electric brake wire underneath your hood to complete the brake controller installation. Once you are under the hood, you would remove the bracket in the corner closest to the driver. Then, you would pull the top and lower covers off your fuse block. You should see a red wire with a ring terminal, and a blue wire with a plug. Take...

  • Recommended Trailer Battery Charging and Controller for 80 AH Battery
    To run a charge wire from your tow vehicle to your trailer battery, you will want to use 10 gauge wire # 10-1-1 along with a 40 amp circuit breaker # 9510 and run that wire to your 1 o'clock trailer connection pin on your bumper connection. Then you will want to make sure your trailer 7-way also has a wire running to the trailer battery positive terminal that has a diode like the Roadmaster Single Park Light Diode # RM-690 to prevent back feeding power. This combination will give...

  • What Does Trailer Battery Circuit Breaker Really Do for Trailer Wiring
    Circuit breakers are a great way to shut down a circuit if there happened to be an overdraw that would otherwise get the wiring so hot that it would melt or even worse catch fire. They also would save any accessories attached to the circuit from getting damaged as well. For the short term you could bypass the breaker if you need to get the trailer back on the road ASAP but I would recommend replacing the breaker as early as possible. For a 40 amp breaker we have the # 9510.

  • Operation 12V Charge For Trailer Battery On Bravo Enclosed Trailer
    On your 2014 Ford F-150 the wiring is there as well as the connections, so they call it a tow package. There are rare times that they don't put in all the relays and fuses like in your case, but that is not common. The way that your system is wired for the battery to charge while the vehicle is on is really nice. This makes it so that if you leave your vehicle connected to your trailer, the trailer battery won't draw from the vehicle start battery so you end up with a non-running vehicle...

  • Solution to Activate 12 Volt 7-Way Trailer Circuit on 2017 Ford F-250
    The simplest solution will be for you to run a wire directly from the truck's positive battery post through a circuit breaker like part # 9510 with 10 gauge wire like part # 10-1-1 to the 1:00 pin of the 7-way and you'll be set. It can be a daunting task trying to track down factory wiring issues as information is limited and modern vehicles are pretty complicated. Bypassing all of that and running a manual wire will be the most reliable way to get the circuit active.

  • Only One Side of Trailer Brakes Lock Up
    The high-pitched whining noise you are describing is completely normal for electric trailer brake assemblies. If only one side of the trailer brakes lock up then most likely you just need to adjust the tension on the shoes like you mentioned. If you want to get more technical then you can test for power on the wire leading into the magnet. If you don't get close to 12 volts with the manual override applied and controller at max settings then you have a wiring problem but if you are getting...

  • Mounting Location For 40 Amp Circuit Breaker On 2011 Ford Ranger
    The 40 amp. In-Line Circuit Breaker, part # 9510, mounts near the battery under the hood of your vehicle, typically on the firewall. I have linked you to a video that shows installation of a 7-way and a circuit breaker. If you do not have the trailer wiring on your 2011 Ford Ranger, I would recommend the Draw-Tite Custom Fit Vehicle Wiring for the Ford Ranger, 2011, part # 18252. This is not a plug and play option, but the # 18252 is simple to install. Locate the wiring harness behind...

  • No Power To Trailer Tow Charge Circuit In 7-way Connector on 2013 Ford F-250 Super Duty
    It is possible for the trailer charging output to activate on the 7-way even if the trailer does not have brakes. Usually on Fords with integrated brake controllers the 12V power circuit is not activated until the trailer is plugged in, the truck's ignition is on and the brake pedal is depressed. You should get a "trailer is now connected" message on the dash in the truck per Ford's tech bulletin. You may need to check the fuses if you are not getting power to the 12V circuit. I took...

    Your camper has the standard 4-way colors which are for the taillight circuits plus an additional circuit. The white is ground, green is right turn/stop, yellow is left turn stop, and brown running lights. Now the red circuit can be a few things but on a camper trailer typically the extra circuit is for charging a battery so you'd need the 5-way adapter part # 20036 installed on your vehicle wiring and would need to run the extra wire of this adapter to the positive post of the battery...

  • Recommended Circuit Breaker for 12v Power on 7-Way
