• Can Hydraulic Brakes of Demco Tow Dolly be Converted to Electric Brakes
  Since Demco uses 3,500 drum brake assemblies part # DMSB24429M and # DMSB24428M what you'd need is similar 3,500 electric brake assemblies like the etrailer part # AKEBRK-35L-SA for the left hand side and # AKEBRK-35R-SA for the right hand side. To wire these up you'd just need 10 gauge wire like the part # 10-1-1 which we sell by the foot. Then to add a 7-way the easiest way to do that is with the 7-way junction box # e99011.

• Parts Needed to Add Brakes to 3,500 lb Trailer Axle
  Since we know you have 3,500 lb axles we can pretty easily pick out the correct parts you'd need to add brakes to your trailer. You'd need new hubs that have integrated drums like with the part # AKHD-545-35-EZ-K which have the very common 5 on 4-1/2 inch bolt pattern. Then you'd need to add matching brake assemblies with the part # AKEBRK-35-SA and you'd be set aside from 10 gauge wiring like part # 10-1-1 which we offer that you'd want to wire up the assemblies with. This is sold by the foot.

• Bypassing Factory Brake Controller and Installing Aftermarket Model on 2018 GMC Sierra 3500
  There isn't anything like an autonomous controller that would step up if the factory controller fails. I'd simply bypass the existing factory brake controller. The GM ITBC, although it works better now than the earlier models has been problematic enough that Tekonsha who provides many of our aftermarket brake controllers has a technical bulletin that specifically addresses how to bypass the factory controller. Let's just say you aren't the only one that's had problems with the factory...

• Bypassing OEM Brake Controller of 2008 Chevy Silverado Recommendation
  Hey Mike, I really like the Prodigy P2 part # 90885 for a replacement brake controller for the OEM controller of your 2008 Chevy Silverado 2500 as this is the most reliable and best performing brake controller so it will work great for you. The wires needed to install this controller on your truck are already there under your dash and you will need to wire them directly to the P2. The wires are located under the dash between the emergency brake and the brake pedal, and the harness will...

• How to Make an Adapter to Go from Semi Truck 7-Way Round to RV Style 7-Way Blade on Trailer
  Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make an adapter to get it to work with an RV 7-Way. For that you would need a trailer side 7-Way round, # PK11702, a converter, # RM-732, and a vehicle side 7-Way RV style, # PK12-707E. A semi-7-Way has separate circuits for the brake lights and...

• How to Bypass Factory Integrated Brake Controller on 2015 Chevy Silverado 2500
  Installing the P3 brake controller # 90195 on your 2015 Chevy Silverado 2500 with factory integrated controller will actually be very simple. What you will do is use harness # 3016 which plugs into a port on the truck already. But you will need to remove the blue wire from the end that plugs into the truck. You will then take a length of wire, # 10-1-1, and connect it to the blue wire you removed from the connector. Route the blue wire through the firewall, under the truck, and to the...

• Which Axle Should Electric Brakes be Installed on with Tandem Axle Trailer
  When installing electric brake assemblies on just one axle of a tandem axle trailer, you will essentially want to choose the axle that is going to be seeing more weight. Typically on utility trailers, most of the weight will be in front of the axles so the brake assemblies will be installed on the front axle. For boat trailers, where the motors are at the rear, you will usually see brakes on the rear axle. I have attached a great article that details everything you will need to install...

• Troubleshooting Voltage Drop from 12V to 7V When Trailer Brakes are Installed
  It sounds like you may have a poor ground connection which is causing low voltage when you are testing. Sometimes it may look like we have a really good ground point but some paint or debris is getting in the way and causing issues. What I recommend doing is taking your trailer brake ground wires and running them up to your main trailer ground location. You will likely need more 10 Gauge Wire # 10-1-1 and I recommend using Heat Shrink Butt Connectors # DW05745-5 because they hold up much...

• Can etrailer Electric Jack e74GV be Used with 7-Way of 2025 Ford F-250
  Hey Jeff, on a lot of newer trucks the 12 volt accessory circuit of the 7-way isn't active until it senses an actual trailer on the wiring which would then mean that a jack like the part # e74GV would not work BUT if this is the case you can bypass the 12 volt circuit by running 10 gauge wire from the positive post of the battery to the 12 volt circuit of the 7-way and it would be active all the time. We offer 10 gauge wire by the foot with the part # 10-1-1 and you'll also want a breaker...

• Replacement Brakes and Axle for 1997 Magic Tilt Boat Trailer
  Hey Michael! I would add hydraulic surge brakes since it is a boat trailer. Dealing with the hydraulic lines and fluid I would say a little more involved upfront, but the better option overall. You will need the following: -Demco Hydraulic Brake Actuator # DM72VR -Hydraulic Trailer Brake Kit - Uni-Servo - Free Backing # AKFBBRK-35 OR -Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet # AKFBBRK-35-D (if you're worried about corrosion) -Demco Hydraulic Brake Line Kit for Tandem...

• Do Electric Brakes Need to Share Ground Wire?
  To wire your electric brakes you will want to run 10 gauge wire # 10-1-1 to one of the brakes and run it to the other brake, using butt connectors like # 05732-2 to connect them. The grounds will not be spliced, each brake assembly should have its own ground; please see the accompanying photo which is from our help article on adding electric drum brakes which I have linked for you.

• How to Charge a Trailer Battery Through a 7-Way Connector
  You can put a maintenance charge on your trailer battery with the 12 volt accessory circuit of the 7-way. The 1:00 position of your 7-way carries this circuit. You would just need to run a length of 10 gauge wire like part # 10-1-1 (sold by the foot), from this pin to the positive terminal of the battery. You should note that this won't charge a dead battery, but it will keep the battery topped off when you are towing the trailer.

• Parts Needed to Add Brakes to Ranger Boat Trailer
  Hey Eli! The first thing you want to do is make sure you have brake flanges on those axles. You also need to take a look at the axle tags and find the axle capacity. More than likely they're 3,500 lb axles so I'll answer based on that. If you have a different capacity you can let me know in the comments. You will need the following: -Trailer Hub and Drum Assembly # AKHD-545-35-K -etrailer Electric Trailer Brakes # AKEBRK-35-SA -etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box...

• Activating 12 Volt Accessory Circuit of 7-Way on 2023 Hyundai Santa Fe
  Hey Danny, we can definitely help but we don't have just a kit for what you need. What you'd instead need is to run a 10 gauge wire like part # 10-1-1 through a breaker like the part # 9510 from the positive post of your battery to the 12 volt accessory pin of the 7-way.

• Can I Use a 7-Way to 12 Volt Power Adapter to Run a Cooler Off of an In Bed 7-Way While Towing?
  Hey Joe, welcome back! How much power draw does your cooler have? The circuits that power your 7-ways are often fused with a 30 amp fuse/relay. The factory and aftermarket options like item # C57010 are ran off of the same circuit. You'll want to make sure you don't overload that circuit and blow the fuse when using the Pollak 7-Way to 12 Volt Power Outlet Adapter item # PK11896. Another option would be to install the Furrion 12 Volt Socket with Waterproof Cap item # FR36XD in the bed...

• Parts Needed to Install Trailer Brakes on a Load Rite Trailer Model UT6512
  Looks like your Load Rite trailer UT6512 has a 3,500 lb axle. Most likely it's a standard 3,500 lb trailer axle but first you have to check to see if the axle has brake mounting flanges. If you can get back to me with whether or not you have brake flanges and the brand of your axle (most likely Lippert or Dexter) I can see which kit we have that may work. Check out the link I attached to see a guide to use for adding brakes to your trailer.

• Recommended 7-Way Wiring And Wireless Brake Controller For A 2022 Toyota Highlander
  Hi Vijay, Since you're wanting to go with a wireless brake controller you can use the Curt Trailer Connector Adapter # C57672 you were looking at and just cap off both the yellow and blue wires with some electrical tape. These can be saved for use later on if you want a hardwired brake controller or have a boat trailer with a reverse lock out solenoid. You'll need to pick up some 10awg wire # 10-1-1 to run from the black wire up to the battery and a 40 amp circuit breaker # 9510 inline...

• Hydraulic Drum Brake to Electric Drum Brake Conversion for 8-247 Hubs
  To convert your 8-247 Dexter hubs # 84546UC3 from hydraulic to electric, you can simply use the same hubs if they are in good shape. If you don't need to replace them, I recommend updating the bearings and seal since you have them apart. For your inner bearing you want # L68149, for your outer bearing # L44649, and then grease seal # 58846. Then for the brake assemblies, I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3.5K # 23-468-469...

• Using 7-Way 12V Power Circuit to Power Trailer LED Interior Lights
  Yes, you certainly can use the 12V auxiliary power circuit on your 7-way wiring setup to power trailer lights. If you refer to the linked photo of a vehicle 7-way connector you will note that the 12V power circuit is carried on the contact at the 1:00 position as you look at the 7-way socket. This is noted by the yellow arrow. An easy way to access this 12V power circuit is to tap into it by using a junction box like # HS381-9000. This box gives you a handy place to install a ring terminal...

• Brakes for Second Axle on Horse Trailer
  Hey Robert! Ideally you're going to get 12V all the way back to the brakes but that typically doesn't happen. What exactly is the issue? Are they not working at all? At 8-9V I would expect them to have most of their functionality to a point you probably wouldn't notice. Are you saying you have 11V at the brake assemblies when you use the jumper pack? Do you have full 12V coming off of your vehicle when you use the manual override on your brake controller? Some typical issues with low voltage...

• Troubleshooting Red Flashing Light on the Curt Venturer Trailer Brake Controller # C74VV
  If you check out the picture that I attached you can see that your Curt Venturer Trailer Brake Controller # C74VV that you installed is detecting an overload or short on the brake circuit of your 2008 GMC Sierra. The wiring adapter # C51515 that you also installed is the correct adapter so now we need to determine if the problem is on your Sierra or your trailer. If you have another trailer with brakes handy then you can simply hook up to that trailer and see if the same thing happens. Whether...

• How To Install a Battery On a Trailer for Use with Electric Jack
  I have attached a photo for you that shows how a 7-way trailer connector is wired. If you take a look at the trailer side trailer connector you will see a terminal labeled "12V Power". If you were to run a wire part # 10-1-1 (per foot) from this terminal on the 7-way trailer connector to the positive terminal on the battery that would then provide a maintenance charge while the trailer is attached and the vehicle is running or the key is in the ACC position. This will depend on how the...

• LED Light On Curt Echo Not Lighting Up Or Pairing To Phone
  When the LED light on the Curt Echo part # C51180 does not illuminate that means the brake controller is not getting power from the 12V pin or the ground is bad. On a 7-way trailer connector, the 12V power function does not need to be connected for the other functions such as clearance lights, taillights, stop and turn lights to work properly so it makes sense that your trailer lights are still working properly. The Echo does need 12V power from the 7-way and will not pair to the phone...
