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

Average Customer Rating:  4.9 out of 5 stars   (75 Customer Reviews)


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


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.


Easy install and works great.


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.


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.

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


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

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


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.


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.


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.


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.


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.


Seems like quality wire. Good insulation. Highly recommend.


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


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


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

Everything is as expected! Top quality and rapid delivery. If You need trailer products this is the place!


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.

  • Can Ground Wires for Trailer Lights Run Back to Ground of Trailer Connector
    What you described will work well for grounding your lights. You can run the ground wires of each of the lights back to the ground wire of your trailer connector and your lights will work great. It's the other acceptable way to ground the lights other than through the trailer frame like you mentioned.

  • Troubleshooting Trailer Wiring Where Prodigy Brake Controller Shows OL and SH Code
    I wish I could tell you exactly where the short is, but you're going to have to start basically at the connector on the trailer and then work your way back to the brake assemblies looking for any additional frays so that you can fix as needed. It is also possible your brake magnets are damaged and they are worn down to the point that the windings are exposed. I attached a help article that details how to troubleshoot brake magnets as well.

  • How to Make Jumper Wire for Testing 12 Volt Trailer Lighting
    The easiest way to get a 12 volt power wire test wiring is to use a jumper wire from a 12 volt battery. One for the positive terminal and the other for the ground. We have 10 gauge wire like part # 10-1-1 sold by the foot which would work well.

  • 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...

  • Troubleshooting 12 Volt Accessory Circuit Not Active on 2002 Chevy Silverado
    On your generation of GM truck the 12 volt accessory circuit wasn't/isn't always active. Under the hood there are a few connections that need to be made to allow that circuit to be active so that you can charge the trailer battery. If you check out the help article I attached you can see exactly what it would take to activate the circuit.

  • Should Wiring for Trailer Brakes be On Front or Rear of Axles
    It's probably smartest to have the wiring that goes to the trailer brake assemblies on the back of axles to prevent rocks and debris from bouncing up and possibly damaging the wiring. Now will your setup technically work? Yes, it will but to be the most cautious I'd consider moving the wiring to the rear of the axle.

  • Can Towed Vehicle have Battery Charged From Tow Vehicle Through Tow Bar Wiring

  • Troubleshooting Weak Trailer Brakes
    Have you tried taking the brake controller's gain setting and putting it all the way up to the max setting and see if the brakes are still weak. If so, then most likely the issue is that the brakes are out of adjustment or the wiring for the brake output circuit is too thin. 10 gauge wire like part # 10-1-1 is the correct gauge to use which you might check to see if you have this. Check to make sure the adjustment wheels of your assemblies are putting a light drag as you turn the wheel...

  • Ford Van TCM Won't Supply 12 Volts to Trailer Jack
    There isn't a way around Ford's wonky 12 volt issues that will allow you to plug in and use your trailer jack, as there isn't a way to fool the TCM, so to speak. The only real solution I can think of - depending on your trailer jack - is to wire it directly to a 12 volt power source with 10 gauge wire # 10-1-1.

  • Trailer Brakes Lock Up with Brake Pedal on a 2007 Dodge Ram 3500
    If the trailer brakes lock up when towing with your 2007 Dodge Ram 3500 on different trailers then the issue is with the brake controller and or vehicle most likely. If the brakes lock up with the pedal then there is probably a sort on the brake output wire that runs from the brake controller all the way back to the trailer connector. If you were to test the brake output pin on the 7-way with the brake pedal depressed are you getting a full 12 volts? If so then this indicates a short in...

  • Troubleshooting Voltage Drop to Trailer Brake Assemblies
    I believe you almost solved the problem when you swapped the wiring, but in reality you needed to use 10 gauge wire like part # 10-1-1 (sold by the foot). You are experiencing a voltage drop due to the long distance of wire that's not thick enough. Replacing all of the wiring on the power circuit and the ground circuit will allow the brakes to have the amount of voltage to apply. I'd run all of the ground wires back to to the main ground harness of the trailer wiring as well. It's also...

  • Trailer Wiring Fault Message on Tow Vehicle and Brake Controller Shows Trailer Disconnected
    For starters, you are correct in that the wires on the braking assemblies are non-polarity specific so that basically means you can use either for power or ground. Now with that being said, it really sounds like you have a short on the brake output wire that runs from the braking assemblies all the way up to the trailer connector. This is going to cause intermittent brake function as well as tricking the vehicle/brake controller into thinking the trailer has been disconnected. The only...

  • Weak Brakes on Multiple Trailers with Same Tow Vehicle
    The issue that you presented points to signs of a short on the brake output wire (usually blue) that runs from the brake controller all the way back to the 7-way trailer connector. My question to you would be where you tested the wire at and got 11.4 volts? If it was directly behind the brake controller then that means the brake controller is in working order. However, the remaining part of the brake output wire that runs from the brake controller all the way back to the 7-way trailer...

  • Should Only Driver's Side Trailer Brakes be Connected to Brake Controller Circuit
    Just to be clear you are saying that only the brakes on the driver's side of your trailer are connected to the wiring for your brake controller? That shouldn't be the case at all as the braking on one side will cause that side to pull on your tow vehicle so at higher speeds your trailer will turn a bit when braking. Double check the brakes on the right side of your trailer to see if they are actually connected to the brake controller circuit. You actually should be able to hear the brakes...

  • Troubleshooting Trailer Brakes That Stopped Working After Parking Trailer for a Few Months
    If the lights on the trailer are working currently and it's just a problem for the brakes I'd recommend just replacing the brake output circuit wire for the trailer with new 10 gauge wire like part # 10-1-1 which is sold by the foot. Most likely in one of the several splices on this circuit there is a short or an incomplete connection which is causing the problem. You could probably mess with the wires enough to get the connection to at least become intermittent. Also try improving the...

  • How To Fix No Electric Brakes On Trailer
    If your trailer has standard electric brakes then the first thing we are going to need to do is test the brake controller.

Once you have power at the max settings have a friend apply the manual override which is usually a bar or button on the exterior of the unit and then test the 1 o'clock pin on the 7-way.

  • Will Trailer 7-Way Charge Line for Trailer and Camper Battery Affect Alternator
    The wire that will carry the 12 volt power circuit from your truck battery to the camper and trailer battery will be small enough you wouldn't be putting too heavy of a charge on either battery to really tax your alernator enough to prevent charging the truck battery. The charge on those two batteries would be at most a maintenance charge and would not top of a dead or depleted battery. We do not have any triple hitch setups at this time.

  • Can Two 6V Batteries be Wired in Series with 7 Foot Distance Between Them
    The 7 foot wire between your two 6V batteries may result in a bit of a voltage drop on the output. The exact amount, if any, will also depend on what wire gauge you are using on the batteries. I do recommend using a thicker gauge wire for your application, as this will present less resistance to the current flow to help with this distance. You can use 10 gauge wire like # 10-1-1, which is sold by the foot.
