All items arrived, except for one missing bolt for the Electric Jack. Additionally, the wheels arrived with numerous scratches on the surface of the mag wheels, indicating they were not adequately packaged. Proper protective material should have been placed over the wheels to prevent them from moving and getting scratched inside the packaging. I am going out of town or I would have had them replaced.



by:

Product showed up on time as promised.



by:

This is almost all of what's needed to install the Autowbrake. I rated 5 stars because the essentials are there, and provide guides when running to the hardware store to buy more ring terminals. The box itself is well built. I didn't use any of the weather-tight crimp connectors. The lack of mounting screws I can understand, because different ones are needed for mounting on metal than wood. I used 1.5" long self-tapping metal screws to mount onto my trailer's tongue.

This box has plenty of room to mount the Autowbrake wiring and the wiring from two 7 way cables. I chopped off the existing 7 way plug and purchased a new plug/cable to have enough wire for installation.

Good kit, but maybe some more ring terminals instead of the weather tight crimp connectors would be nice.

etrailer is an amazing company. This was the very first time I placed an order with etrailer and it was way above and beyond my expectations. Everything I needed for my trailer was in stock. I placed my order on a Sunday night and it was shipped for FREE the following day. My order was delivered 4 days later in excellent condition with the correct items that I ordered. It was easy to track my order from the warehouse to my front door from the shipping email that I received from etrailer. Thanks for the great experience! You will always have my business!! God Bless!

  • Installation Kit For Autowbrake Electric Brake Controller
    The Autowbrake # 3430001 installs on the trailer side so you would generally just utilize the 7 way plug already on the trailer. We do recommend using a junction box to connect the Autowbrake wiring harness. We actually make an installation kit specifically for this purpose with part # 3430001-JBK. This will include everything you need for installation.

  • Parts Needed to Install Electric Brakes On a Tandem Axle Trailer With 3,500 Torque Axles Salt Water
    With your trailer being in an environment where it is exposed to both salt water and fresh water I would highly recommend going with a disc brake setup. There are much fewer components on the brakes to become damaged from the elements with disc brakes. You will need 4 of the DeeMaxx Disc Brake Assemblies # DE89YR with a Hydrastar Electric-Hydraulic Actuator w/ Line Kit # CAR-HBA16-2. You will most likely need a Adapter Module # HBA-CAM for your factory brake controller but be sure to check...

  • Parts Needed For Installing Electric Trailer Brakes Onto a Trition UT16 Tandem Axle Utility Trailer
    It would appear your Trition UT16 utility trailer will have axles using the standard #84 spindle dimensions. You will want to verify this is what you have by disassembling one of the hubs and measuring the spindle, see image below. The spindle will be 1.063" in diameter for the outer bearing, 1.378" in diameter for the inner bearing and 1.719 in diameter for the grease seal. You will also need to measure the mounting holes for the brake flanges. The mounting holes should be spread 2-13/16"...

  • Parts Needed to Add Reverse Function for TecNiq LED Trailer Tail Light
    To add the reverse function on your trailer you need a 7-Way connector and enough wiring to run from the front to the back of your trailer. Here are the parts you need to get the wiring from your tow vehicle back to the TecNiq LED Trailer Tail Light # TN33XR: - Junction Box Kit # 3430001-JBK - 7-Way Molded Trailer Wire Connector # H20043 - 16 Gauge Wire # 16-1-1 - Butt Connectors # DW05744-10 - 3-Wire Pigtail # A45PMB (per light) - 2-Wire Pigtail # A42PMB (per light)

  • Parts Needed To Add Electric Brakes Onto a 3,500LB Dexter Axle Without Brakes
    The Dexter Electric Trailer Brake Kit # 23-26-27 is the correct kit for your Dexter 3,500lb torsion axle studs. This includes both the left and right hand side brakes for one axle. It does not include a hub. I do recommend looking at the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-468-469 instead as the brakes adjust while you drive saving you on having to adjust the breaks as they wear. This also maintains a more constant brake feel with less adjustment required on the vehicle...

    We do have a separate Junction Box # 3430001-JBK you can combine with the Hopkins 7-Way Molded Trailer Wire Connector # HM20048. This harness is 11' long which will give you approximately 10' of cord outside the junction box.

  • Converting a 1995 Jayco Eagle 12 UDK To Use Electric Trailer Brakes
    First you will need the Electric Trailer Brake Kit # 23-47-48 to replace your hydraulic assemblies. We have the Dexter Trailer Hub and Drum Assembly # 8-173-16UC3 to get you a 4 on 4 mounting pattern. You will need to disassemble one of your hubs to verify it will fit the new hub as your axle is produced before they maintained records for their axles. This hub uses inner and outer Bearing # L44649 which is 1.063" inner diameter. For the wiring you will go from the Hopkins 7-Way RV Style...

  • Parts Needed to Switch a Trailer From Surge Brakes To Electric Over Hydraulic Brakes
    First you are going to need either a Drum # DH54FR or Disc # DH94FR brake actuator depending on what type of brakes you have. Also be sure to check with the local laws where you live as many states are now requiring all trailer axles to have brakes if over a certain weight. If this is the case I would need to know what axles/brakes you currently have. You will also need a Breakaway Kit # 3802311, Junction Box # 3430001-JBK, and 7-Way # H20046. You may also need a Flexible Brake Line #...

  • Electric Trailer Jack Recommendation for a 7,500 lb Boat Trailer
    Hey Ryan, thanks for reaching out! The only true electric trailer jack made to fit a standard boat trailer with a pole tongue is the Fulton XLT Powered Drive Trailer Jack # F141401. Even though this is the only option available, Fulton has added some provisions (like the ZMax finish and stainless ACME screws) to help make it more durable and built to resist corrosion from water. A properly loaded trailer will have a tongue weight that is 10-15% the weight of the fully loaded trailer so...

  • Replacement Trailer Brakes For 2000 Damon Camplite Pop-Up Camper With AL-KO 8440 7" Drum Brakes
    Your AL-KO 8440 drum tells me you have a 7" brake drum with a 5 on 4-1/2" bolt pattern. This will need 4 of the Easy Grease Trailer Hub and Drum Assembly # AKHD-545-2-EZ-2K if you are needing to replace the drums themselves. For the brake assemblies you will need 2 of the Brake Kits # AKEBRK-2. We do have the Mounting Hardware # BRKH7 for the brake assemblies as your hardware may not be in the best condition with the age of the 2000 Damon Camplite pop up camper. We have 12 Gauge Wire...

  • Parts Needed To Wire a Tandem Axle Trailer With a 7-Way and Full Length Ground Wires
    What you are looking to do is acceptable. Here are the parts I would use working on this type of project. The 25 Ft 4-Way Trailer Wiring Harness # A25W2GWB has full length ground wires which will run down the side of each frame and carry the wiring for the tail lights and running lights. You will be able to cut off the 4-way and attach the wiring to a Junction Box # 3430001-JBK. The junction box includes ring terminals for connecting all the wires for the lights, brakes, and a 7-Way Cable...

  • Parts Needed To Install Electric Drum Brakes On a PWC Trailer With 3,000LB Axle
    Thank you for the pictures Matt. I do see you have the backing plate for the brakes so you are most likely going to have #84 spindle since your axle has a 3,000lb capacity. You can verify this by removing one of your hubs and measuring the landings for the grease seal(1.719"), inner bearing(1.378") and outer bearing(1.063"). If this matches what you have you will want the following parts. Electric Drum Brakes # AKEBRK-35-SA Hub/Drum # AKHD-545-35-G-EZ-K Qty 2 Junction Box # 3430001-JBK...

  • Autowbrake Electric Brake Controller VS Tekonsha Prodigy RF Wireless Trailer Brake Controller
    Both the Autowbrake Electric Brake Controller # 3430001 and Tekonsha Prodigy RF Wireless Trailer Brake Controller # TK94FR are great options to add a brake controller to the trailer. This is ideal if you have one trailer that you need to use the brake controller for. The Autowbrake will require you to wire in the module to your 7-Way Junction Box # 3430001-JBK. If you do not feel comfortable with wiring the Tekonsha simply plugs in line on your trailer 7-way. Both controllers are proportional...

  • Parts Needed For Adding 7-1/4 Brakes To Trailer With 2,000LB Axle
    The Easy Grease Trailer Hub and Drum Assembly for 2K Axles # AKHD-545-2-EZ-1K includes the 1" inner diameter Bearings # L44643. The Assembly # AKHD-545-2-EZ-2K includes the 1-1/16" inner diameter Bearings # L44649. To determine which ones will fit your axle you will need to remove the grease cap and spindle nut to find the number on the outer bearing. If there is not one of the bearing numbers stamped on your bearing you will need to measure the spindle using a Digital Caliper # PTW80157....

  • Recommended 7 way Connector for 2017 Dodge Grand Caravan Using Autowbrake
    The Autowbrake # 3430001 is a great choice! To add a 7 way to your 2017 Dodge Grand Caravan you'll want to use the # ETBC7L, since it doesn't require the wiring of a brake wire into the vehicle like the # ETBC7. You will still need to run a wire for the 12v power, but other than than it's going to be really easy to install since it plugs into your existing 4 way. To complete installation of the Autowbrake I recommend using the Junction Box and Installation Kit for Autowbrake Trailer-Mounted...

  • Parts Needed to Install New Trailer Plug and Junction Box on Trailer
    I have a solution for you, and it sounds like you're maybe looking for some sort of plug and play option that you can use as an extender into the junction box, but that does not exist. Your best bet is just to cut the plug on your trailer off and wire the loose wires directly into the junction box; you'll then run a new plug out of the junction box to add the new trailer wiring plug.

  • Parts Needed For Installing Trailer Brakes On a Yacht Club Single 3,500LB Axle Pontoon Boat Trailer
    The best option would be to go with Disc Brakes # DE66YR. These are the best option as they repel water better than other trailer brakes and will offer superior braking. This will require the Zinc-Plated Brake Actuator # T47457107K and Brake Line Kit # HS496-251. The brake actuator uses a electric lockout so you will need a 5-way for your tow vehicle. If you have a 7-way then you will need an Adapter # A75TB or a Kit # C57187 can be used to change a 4-way to a 5-way. You could also go...

  • Parts Needed To Give A Dexter 3,500LB Idler Axle Electric Drum Brakes
    You can use the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-468-469 as long as your Dexter Axle does have the Brake Mounting Flange # 4-35, otherwise you will need to have those welded on. These brakes are great as once you have them initially set you will not have to adjust them periodically. They will automatically adjust which improves braking quality and life. The Dexter Trailer Hub and Drum Assembly # 84556UC3 does use the common Bearings # L44649 and # L68149 that come on...

  • Parts Needed to Add Electric Brakes to a 6x10 Trailer
    There will be a few parts needed to add electric brakes to your trailer. First, you will need to have a flange on the axle that a brake would bolt to. If you do not currently have this flange, you will need to add something like the Brake Mounting Flange # 4-35. This is designed for a 2 3/8" axle and will have a standard bolt pattern for a 3,500 pound braking set-up. With that being said, the etrailer.com # AKEBRK-35-SA will bolt directly to the # 4-35 with the # BRKH10B mounting hardware....
