10 Gauge Primary Wire - Blue - per Foot - 10-1-1

Average Customer Rating:  4.9 out of 5 stars   (76 Customer Reviews)


Exactly what I needed to re-wire my trailer. Fast shipping and good price.


Was larger gauge than I needed but worked just fine. This 10 gauge wire is blue but my stock wiring was about 14 gauge but since the used a circuit breaker to cross connect it was not a problem.


Very heavy good gauge wire for supplying 12VDC power to my trailer.


Fast delivery - Ordered on 9/29/17 - Received on 10/4/17
Excellent heavy gauge wire!
NOTE for etrailer managers. I am a technical person by nature and speaking only for myself, when I buy and pay for a specific amount of something, I expect to get that amount. I'm not pinching pennies with you here; BUT, I bought 30' of this wire and when I received it, I measured it twice and came up with 29' 9". Most places I've dealt with in the past where I buy wire, angle iron, etc.. would give you a couple of inches or more than you ordered versus a couple of inches shorter than what was ordered. Very stingy in my opinion and not fair to your customers.


Easy install and works great.


Order accurately filled, (I even called back to add some items). The order even came more quickly than I expected. Quality of the parts appears to be excellent!

Thank you!

Working fine. No problems.

Excellent brake controller. etrailer was prompt in shipping and service outstanding. Would definitely buy from etrailer again.

This brake controller is working great. Would recommend it Easily adjustable for driving conditions
Gerald - 12/09/2018


Ordered a pair of Dexter electric brake kits for my trailer. Everything arrived within a few (3) days in good shape. Installed on the trailer, everything works as advertised. I have ordered from etrailer several times over the past few years. Always great service and prices. Customer service and tech assist is especially good with these folks. I would send pictures but the trailer is out working.


The wiring harness set is flawless and the installation went smooth, even for this less than electrically inclined guy. A couple hours or work and I was on the road towing with confidence


Couldn't be happier. Bought a couple of 4 to 7 way adapters, some 10 gauge wire and a couple of 40a breakers. Recommendations from etrailer were thorough and well done.
All installed on both vehicles ... both working just great.


The wire itself seems okay, although the packaging wasn't great. Ordered 75 feet of wire along with a coupler. The wire was coiled in the bottom of the box, with the coupler sitting on top of it in direct contact. I noticed some nicks in the wire insulation as a result of the coupler edges hitting it during shipping.

eTrailer did a great job of shipping quickly! Order packaging needs some serious attention.


Not installed yet


The wire was perfect for the application (electric trailer brakes). The sales person, William, who helped me, was most helpful.


ettrailer was extremely helpful with adding brakes to my utility trailer. This wire was just one component in the upgrade. Thank you etrailer. I would definitely recommend them.


This served its purpose for installing a trailer battery charge line. It was nice that I could order a specific length from retailer since I didn't need a whole roll.


Very happy with the wiring. Works well, easy install. less memory then I expected. Nice having power from my tow vehicle to my trailer.


Ordered several electrical connectors,wire and a wire tester .. all items came in good condition ,looking forward to using the tester as soon as I can I am sure it will do the job.


Nice thick sturdy wire, I used it to run 12v power supply from battery to circuit breaker then to to 7 way plug.


Good price, and just what I needed for carrying the heavier loads needed for charging the trailers on board battery, and running the refrigerator/freezer.


It's been a long while since I've ordered anything from etrailer, but, as usual, you folks came through in flying colors. The package was boxed well, shipped on time and the correct products, that's a real plus in today's internet shopping zone.


Great service as always!! Fast delivery! Etrailer has it all covered with product and install information, they make it easy!!


Seems like quality wire. Good insulation. Highly recommend.


Product arrived as promised and everything works great. The staff at etrailer I worked with was fantastic. Thanks, Brian


I just now got it and don't plan on installing for a while. thanks hugh

Very good

It's been a little over a year since I used this to wire brakes for my trailer and no problem thus far.

  • Troubleshooting Electric Drum Brakes That Do Not Grip Despite Functioning Magnets
    Based on your troubleshooting efforts so far I suggest that you test the trailer brakes without using a vehicle and brake controller; you can test the trailer brakes directly by applying +12V power and ground to the appropriate contacts on the trailer plug. Please refer to the linked photo. A set of jumper cables and 10-gauge wire like # 10-1-1 or # 10-2-1 make it simple enough to "hot wire" the brake circuit with the full power from your vehicle battery or a well-charged spare. If you...

  • Gauge Wire Recommendation for Wiring up Trailer Brakes
    I'd recommend using 10 gauge wire like part # 10-2-1 (sold by the foot) for the brake power and ground wires as this will be more than adequate and will ensure you get plenty of amperage to activate the brakes.

  • Troubleshooting Error Codes SH and OL on a Tekonsha Prodigy Brake Controller
    The first error code, SH, you are seeing on the Prodigy Brake Controller (instructions linked below) means the brake wire sees a short circuit during idle condition. The second code, OL, indicates an overload condition during operation. For the first code, SH, the most likely problem is a pinched wire or at some point the wire insulation has cracked or been worn to the point where the copper wire inside is making contact with the trailer frame or another metal part. To find the problem,...

  • Is the 10 Gauge Blue Primary Wire # 10-1-1 UV Outdoor Rated
    I spoke with my contact at Redline and he informed me that this 10 Gauge Blue Primary Wire, part # 10-1-1, is rated for general outdoor purpose and would be considered UV exposed outdoor rated. You would not have to worry about UV damage to this wire if you were to use it in an outside application.

  • Troubleshooting Error Code 0.9 on a Tekonsha Prodigy Trailer Brake Controller # 90185
    Even without the trailer connected, the 0.9 error code on the Tekonsha Prodigy Brake Controller is indicating that there is a ground problem to the brake controller along the white wire. Depending on the vehicle, the wire could be connected through tow package wiring, a factory plug or port, or hardwired directly to the negative battery terminal. If it is connected to tow package wiring that you had to splice into, check the connection. If it is intact, make sure it is the ground wire...

  • How Does a Trailer Receive Maintenance Charge From 7-Way Connector
    Basically all you would need to do is run 10 gauge wire like part # 10-1-1 from the 12 volt pin of your 7-way to the positive side of your trailer battery and it will receive a maintenance charge while it is connected to your tow vehicle.

  • Wire Gauge Recommendation for Wiring Up Brake Output Circuit on Trailer
    The heavier gauge the wire the better. We recommend 10 gauge wire like part # 10-1-1 (sold by the foot), for wiring up the brake output circuit. Since the wire is so long it's important to go with a thicker wire to reduce resistance even though the brake magnets use thinner wire. Especially since the wire gets teed off and ran to multiple brake assemblies.

  • Ineffective Braking on Car Hauler Trailer Towed By 2008 Lincoln Navigator
    There are a few things that could be causing your trailer brakes to preform poorly. As a start, make sure your trailer is not overloaded. If it is a 2 axle trailer with brakes only on one axle, you might consider adding brakes to the second axle. Even though the weight carried on the trailer might not be exceeding the trailer axle capacity, one braking axle might not be enough to efficiently stop the trailer when it is loaded. It is possible that your brake output wire is of too small...

  • Is the Deka 10 Gauge Primary Wire # 10-1-1 19 Strand Wire
    Yes, the Deka 10 Gauge Primary Wire, # 10-1-1, is 19 strand wire. I pulled a piece of wire from my warehouse to verify this.

  • Availability of 10 Gauge Wire
    We do sell a 10 gauge wire by the foot designed for 12 volts. For that you would want the part # 10-1-1. You'd need to order the quantity of this in the amount of feet you would need.

  • How to Charge Trailer Battery with Power from Trailer Connector Socket
    On your trailer's 7-way the pin in the 1:00 position is the 12 volt power circuit and would be what you'd want to run to your trailer battery. Basically this circuit would get ran to the positive terminal of your trailer's winch battery and it would help keep it topped off when you're towing. It wouldn't be able to recharge a dead battery though. I'd recommend 10 gauge wire for this like part # 10-1-1 which is sold by the foot. Then your winch would get powered off of that battery by running...

  • How Does a Trailer Battery Get Power from Trailer Wiring
    To connect a 7-way to a 12 volt battery all you would need to do is run a length of 10 gauge wire like # 10-1-1 (sold by the foot), from the 12 volt accessory post of the 7-way (the 2:00 position), to the positive terminal of the battery. If you have a trailer jack that uses a 7-way style of connector for attaching to the trailer you could easily cut the wire from that connector and run it straight to the battery.

  • Does There Need to be a Fuse Wired in to the Blue Wire of a Brake Controller
    It is not necessary to wire a fuse inline of the brake controller circuit blue wire. In fact, if you did install a fuse and the fuse would somehow blow while your are in transit, you will loose your trailer brakes. The amperage that is sent to the brake magnets on this wire is very low. There will be no issues with amperage overload on the blue wire.

  • How to Make Ground Jumper Wire for Trailer Lights
    You would need to take a section of wire like the part # 10-1-1 (sold by the foot), and on one end run it to the main ground circuit on the trailer connector and then from there run it to each of light assemblies. This will bypass using the aluminum frame for grounding which doesn't work well because aluminum does not conduct electricity well.

  • Does Brake Output Circuit of Trailer Wiring Connect to Brake Magnet Wiring
    I believe you are referring to the graphic I attached to this page that has both wire colors you mentioned. The blue wire would be the brake output circuit that comes from the trailer connector. The black wires represent the leads for the brake magnets of the assemblies themselves. So both wire colors do connect to each other.

  • Troubleshooting RV Electric Brake Assemblies Receiving Different Voltage when Brakes Applied
    It's possible that the brake magnets on the underperforming assemblies are bad, as you mentioned in your question. There are a few ways you can test the magnets which are detailed in the article I have attached for you to review. I also recommend looking at the wiring that is going from one side to the other on your trailer. Depending on what gauge wire you are using, switching to a higher gauge like # 10-1-1 might help. Check for any pinched or damaged wires and fix them as needed. The...

  • Troubleshooting Brake Controller That Doesn't Power Up on 2000 Ford F-250
    The black wire of the controller is the one that carries power, and the white is the one that carries ground. Those two wires are the ones associated with powering the brake controller up. Most likely you have a blown brake controller fuse or relay under the hood of your truck. Check all fuses related to that and I bet you'll find it's blown. Other option is to run 10 gauge wire like part # 10-1-1 from the positive post of the controller to the black wire of the controller to bypass all...

  • Can Trailer Battery Be Charged Through Trailer Wiring Connector
    The gauge wire used for the 12 volt pin of a 7-way is light enough that you'd never be able to charge a dead battery on a trailer with it, but if you were in a situation where you had a battery with a solid charge on it that needed to be kept topped off while traveling charging it through the 7-way will work just fine for that. Basically the amperage is so low that it can't really put a heavy enough charge on it to bring a dead battery back to life, but after some light use on a charged...

  • Troubleshooting Boat Trailer Wiring Issue Where Light Go On And Off When Safety Cable Is Moved
    Since when you move the safety cable the lights come on and off, it is a dead giveaway that the ground wire connection on your trailer is bad. I recommend cleaning that connection and making sure you have a bare metal on metal ground without corrosion or debris. You may need to relocate the ground for your wiring if you can't solve the issue by cleaning up the location of the current ground to the trailer frame.

  • Troubleshooting Voltage Drop from Vehicle Connector to Trailer Battery
    Since you are still getting 13V at the trailer battery, it's unlikely that the voltage drop is caused by any incorrect wiring connections. The voltage drop you are experiencing from the 7-Way on your vehicle to the trailer battery is instead likely due to the gauge of the wire itself that is being used. To reduce this voltage drop, I recommend going to a thicker 10 gauge wire like # 10-1-1, which is sold by the foot. A thicker wire will result in less of a drop and will carry more current,...

  • Hopkins Impulse Brake Controller Reading E1 When Manual Override Is Engaged
    I reached out to my contact at Hopkins and it sounds like everything is functioning correctly except for the E1 code when you hit the manual override. That tells us that there is a problem somewhere on that blue controller output wire. There is a short somewhere to ground. This could be a nick in the wire insulation or it could be corrosion at the connector. I recommend cleaning all your contact points and tracing your wire if that doesn't solve your error code to check for issue....

    You would need to run a length of 10 gauge wire like part # 10-1-1 (sold by the foot) from the 12 volt accessory circuit pin of the 7-way to the positive terminal of the battery. This will put a maintenance charge on the battery but it will not charge a totally dead one.

  • How to Activate Trailer 12V Power Feed on Factory 7-Way in 2016 Silverado
    Some trucks do need an under-the-hood connection of wiring to activate the 12V trailer power feed and the trailer brake controller power input feed. This process is outlined and illustrated in the linked article, in the section titled "Finalizing Connections for the Brake Controller". The ring terminal for the 12-volt power lead for the 7-way trailer connector is located to the left of the power distribution box. It is taped to a wire harness under the power brake booster.
