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.


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.


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.

This brake controller is working great. Would recommend it Easily adjustable for driving conditions

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.


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.


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.


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.


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.


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


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.


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


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

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.


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

  • 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 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...

  • 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.

  • 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...

  • 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 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 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...

  • 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...

  • One Trailer Brake Assembly Locks Up On Trailer
    If only one braking assembly on your trailer is locking up with the trailer connected then this could point to signs of a wire short. The first thing I would do is check the ground for the assembly that is locking up. The ground should ideally be removed, the surface should be sanded down, and then reattached with new hardware. Once the ground is checked you will then need to turn your attention to the power wire. I recommend you trace the power wire from the splice point to the problem...

  • What Size Wire Is Needed for the Fulton XLT Powered Winch
    The correct gauge of wire that will need to be used to rewire a winch will depend on both the amount of amps the winch draws as well as the distance between the winch and power source. If you can provide me with these two key metrics then I would be glad to provide you with the proper gauge wire that will need to be used. For example, the Fulton XLT Powered Winch with Rugged Strap 500621 that you referenced has a max amp draw rating of 200 amps. In order to use this winch or one similar...

  • Brakes Engage On Grand Design Momentum While Hooked Up To Shore Power
    The shore power circuit for your trailer should not have anything to do with the trailer's brakes as they are on completely different circuits and use an entirely different type of current (AC vs. DC). However, if you have a short on the AC power circuit and the circuit is sending power to the trailer frame/body which is commonly referred to as "Hot Skin" then that could then cause the brakes to engage via the ground wire. Therefore, I recommend you disconnect shore power and see if the...

  • Troubleshooting no Power to Some Pins on 2000 Dodge Ram
    The good news is you have narrowed it down to the issue being on your truck and have done some good troubleshooting already. If you are not going getting power to the electric brake pin and running light pin, the very first thing you want to do is take a look at your owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order and replace if needed. If those are fine the issue is likely a short in your wires going to those pins from your truck...

  • Would Battery Charger for Trailer Battery Connected to Truck Also Charge Truck Battery
    If the 12 volt accessory circuit on your truck's 7-way is active all the time then yes the charge that is put on the trailer battery will also charge the truck battery since they are connected. Most likely due to the length and gauge of the wire it wouldn't put much of a charge on the truck battery.

  • Troubleshooting Chevy and GMC 12V Wiring on 7-Way Connection for Towing
    Under the hood of many Chevrolet and GMC vehicles there is a connection required for activating the 12V auxiliary power feed on the 7-way. 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. Cut the tape to release it from the harness. Then run the wire to the front of the power distribution box and hook the ring on the right post. You can refer to...

  • Connecting the Blue Wire to a Brake Controller Installation on a 2016 Ford F-150
    You'll just need some additional wire to connect up to the front end of the truck, available as part # 10-1-1. You'll use the wire in this bundle to connect the blue wire up to the blue wire on the brake controller to complete the circuit. Some models do have a pre run blue wire and a pre run orange or red power wire, but they're a little hard to get to.

  • 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.

  • Can I Power Lights On My Horse Trailer With a Small Battery Installed on Trailer
    The location of where to install the battery really depends on the trailer. Typically it's installed in the tack room area in the front of a horse trailer but it really only matters that it's out of the direct way of the weather and is a place you'd be able to reasonably install the battery. For wiring you'd want to use 10 gauge wire like part # 10-1-1 which is sold by the foot. I'd recommend routing the wire in the same way from your trailer connector along the gooseneck of the trailer....
