  • Recommended 4-Way Trailer Connector Installation On 2013 Ford F-150
  • If your F-150 has a 4-way connector it is typically located near the rear license plate. It can be tucked back up behind the bumper and may even be taped or zip tied to other wires or the frame of the truck. If there is no trailer connector, you will need to use the Draw-Tite 4-Pole Hardwire Kit, part # 18252, and locate the correct circuits behind the vehicle taillights for installation. The kit includes a circuit tester and the quick-splice connectors needed. I have attached a...

  • Repairing Cut-Off Trailer Connector on 2011 Ford F350
  • I'm assuming you're speaking of the factory tow package harness located behind the rear bumper. Ford might offer a harness that would allow you to plug in further up the truck bed, but the best bet we offer would be # PK11998 pigtail or if you're also missing the trailer connector, part # HM40975-11998. The pigtail would need to be connected to the cut wiring, so I'd recommend using a circuit tester like part # 40376 to determine which wire carries which circuit. Have a helper activate...

  • Recommended 7-Way for 2012 Ford F-150 XLT Without Factory Tow Package
  • The Bargman 5th Wheel and Gooseneck 90-Degree 7-Way Pigtail Harness # 51-97-407 is a general-purpose wiring harness kit that is not vehicle-specific. This is intended for hardwired installation to the vehicle's existing wiring using the pigtail leads. Do note that the function carried on each wire is noted in the products specs. Matching wire functions is the best way to install a harness since wire colors are not 100-percent standardized. If you do not have any tow wiring on the truck...

  • Troubleshooting 4-Way Flat Factory Connector Only Testing for Power on Turn Signals
  • Since you have a factory tow package wiring, I recommend checking the tow package fuses to be sure none of the fuses are blown. If the fuses are fine, next you will want to check the wiring behind the bumper for any damage. There may be a short from a cut or pinched wire that is causing problems with the 4-Way connector. Next you can test the functions of the 4-Way with the tester grounded on the ground pin of the connector. Using the 4-Way connector's ground will ensure that the...

  • 7-Way Trailer Wiring Connector Recommendation for a 1999 Ford F-250 with Factory 4-Way
  • To wire in the # HM40975-11998 would require a couple fuses and relays. Your best option is going to be to get the # 118243 instead as it comes with the fuses and relays needed. It also has a square connector that will mate right up to the trailer wiring connector you have on your truck already. Trying to install the harness you have would be quite a headache. I would strongly recommend you get the part # 118243. I attached an install video for this harness for you to check out as well.

  • Trailer Wiring Recommendation for a 2004 Ford Escape without Tow Package
  • For your 2004 Ford Escape you would actually need a powered trailer wiring harness like the part # 46255 that uses the power from the vehicle battery to power the trailer taillights instead of the taillight circuits of the vehicle for the trailer taillights like the # 119178 does. A powered harness will have a wire that runs up to the vehicle battery and then uses the wires run to the vehicle taillights as signal wires. If you use the # 119178 on your vehicle you may end up shorting...

  • Brake Controller and Wiring Harness for a 2016 Ford F-150
  • If your new Ford F-150 came with the factory installed brake controller then you would not have to add an aftermarket one to activate the trailer brakes. If the truck does not have the factory controller and you need to control the brakes then you will need one. For a brake controller I recommend the P2, # 90885, because its easy to set up and use and it is reliable. You will also need the appropriate wiring harness to plug the controller into the truck. You did not mention the year...

  • Should an Electric Trailer Jack Run Off of a Trailer Breakaway Battery
  • The trailer jack should very much NOT be powered by the breakaway battery. That was likely done by the previous owner for convenience. The breakaway battery is a dedicated battery for the breakaway system only. It needs to be able to apply the trailer brakes on full for 15 minutes. If the jack was to run down the battery then the breakaway system would not be able to power the brakes for long enough. Also, a breakaway battery is too small for the power needs of a jack. Most breakaway...

  • Replacement Trailer Connector for a 2012 Ford Super Duty
  • The harness you see pictured in connector # HM40975-11998 plugs into the back of that connector so it would look like the opposite of what is on the back of the connector. If you do not need the wiring harness part then you would just use # HM40975 or # 20119. If you do need the harness it will have to be wired into the trucks tow package wiring by function by testing the vehicle wiring using a circuit tester such as # 3808 to determine the functions. The wire functions of the harness...

  • Troubleshooting Brake Controller Wiring On 2003 Ford F-250
  • You should not show power to the brake output wire unless the brake controller is sending it. You may have something wired incorrectly at the 7-Way. You want to make sure your connector is wired the same as the attached photo of a 7-way connector. If not, then you want to change the wiring and place the wires in the right order. You can also check to see if any of the wires are touching each other inside the 7-Way. Check for corrosion or dirt and clean it up as that can cause shorts...

  • Using a Switch and Trailer Mounted Battery to Power Interior Trailer Lights
  • What I recommend is to wire up the lights via a switch installed inside the trailer and connected to the battery. You can mount the battery where needed but 10 gauge wire will be too large for lights. A lot depends on the lights and how much power they draw but 16 gauge wire such as # 16-1-1, sold by the foot, would likely be all you need. For a switch you could use something like # PK34513. It is a basic on/off toggle switch rated for 10 amps. Another option is # PK33300 rated for...

  • Replacing the 7-Way/4-Pole Trailer Connector on 2010 F-350 Super Duty-King Ranch
  • Your F350 should have come with the factory tow package. You'll need to figure out if the connector you currently have is damaged, or if the problem might be further down the line. Follow the wiring for the existing trailer connector until you find the round US car connector. Unplug that connection. On the vehicle side of the connection, use a circuit tester like part # 40376 on the connector as a helper activates each taillight function. If you're getting signal for the running lamp, right...

  • Troubleshooting Trailer Connector When Trailer Brakes Lock Up When Connected To Vehicle
  • To test the connector on your 7-way you would need a circuit tester like part # 3808. Test the pins on the vehicle side to determine what the pin functions are. You would need to determine which pins show power when the brakes are pressed on the vehicle. They would be your left brake, right brake, and the brake controller pin. If you have a proportional brake controller there will be very little power on the brake output pin. You would need to test the pin by using the manual override on...

  • Aftermarket Trailer Wiring Recommendation for a 2014 Ford Escape to Bypass Factory Wiring
  • If you wanted to bypass the Ford trailer wiring on your 2014 Ford Escape you could pretty easily do that with the Tow Ready wiring harness part # 118566 as it has been confirmed as a fit for your vehicle. I attached an install video. What you described is pretty bizarre. When the lighting is behaving strange you can test the voltage of the 4-way with a circuit tester like part # 3808 to see if the vehicle or the trailer is at fault. I attached a video that demonstrates how to do this.

  • Trailer Lights Not Working When Connected to a 20014 Ford F-150
  • On a vehicle side trailer connector the brake lights and turn signals are on the same circuits (one each for the left and the right) because that is what the trailer uses. So it is not unusual that the tester you are using showed power on the turn signal indicators when the brake pedal was pressed on your 2004 Ford F-150. They should also come on when the turn signals are used. Assuming that all the functions work on the truck side, the problem must be on the trailer side. It could be...

  • Fifth Wheel 7-Way Trailer Wiring Recommendation for a 2008 Ford F250 Super Duty
  • I can't recommend the installation of 7-way trailer wiring in the stake pocket of a truck. Your best bet would be to install it near the wheel well like it is intended for. Having a 7-way mounted facing up like what you are interested in doing wouldn't be a great idea because even though this connector has a flap on it water would still end up getting trapped in the connector.

  • Recommended Trailer Wiring Harness for 2014 Ford Explorer Without Tow Package
  • Your Explorer might have the rectangular plug located to the right of the muffler on the passenger side of the vehicle (see linked video). If it does, you could use the # 118540 harness from Tow Ready. The harness is a plug and play install, pretty easy. If you do NOT have the connector, you'll need to hardwire the trailer connector in place using the # 119147KIT wiring harness. I've linked you to a video showing that harness being installed on a different vehicle. The procedure would...

  • Recommended Taillight Converter for 1993 Ford Mustang
  • It seems like you've diagnosed your problem. You'll need a taillight converter installed on your vehicle because of its separate taillight system. As you surmised, the converter takes the three signals from the right turn, left turn and brake and combines them into two signals, one for right turn and brake and one for left turn and brake. A converter like the # 119178 is exactly what you'd need. You can simply cut the plug off your existing 4 pole, and attach its yellow, green, brown...

  • Will Curt Upgraded Circuit Protected Wiring Harness # 56146KIT Fit 2015 Ford Escape
  • If you are looking for the most economical way to add trailer wiring to the 2015 Ford Escape that you are purchasing, you can use the Curt 3 Wire to 2 Wire Converter, # C56190. The Escape is going to require a heavy duty converter like the one in part # C56190 so we can not recommend reusing the wiring harness, # 56146KIT, from your 2012 Cadillac SRX. You may want to consider going with a plug-in option like the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118566....

  • 7-Way Trailer Connector Needed for 2015 Ford F-150
  • I recommend using the Hopikins Adapter 4- to 7-Pole and 4-Pole # 37185. This connector will work with the existing 4-way connector on your vehicle. Using this adapter, you will be able to tow trailers with 7-way connectors or 4-way connectors. There are a few additional parts we used when installing this connector. When connecting to your existing 4-way connector, dielectric grease # 11755 will help to protect the connection. We recommend securing this connection with a zip tie and...

  • What is the Wire Gauge Used in Curt 5th Wheel/Gooseneck Wiring for 2015 Ford F-250
  • I spoke with my contact at Curt about wiring harness # C56070. He said that there are 12 to 14 gauge wires used. The 12 volt and ground wires would be the larger 12 gauge. Hardwire harness # 51-97-407 uses 10 gauge for the ground and 12 volt circuits. But the difference between 10 and 12 gauge wire for this application is not going to be a problem so I would stick with the custom harness # C56070.

  • 7-Way and 4-Way Recommendation for a 2007 Ford Expedition
  • The only 7-way/4-way we offer that would do what you are looking to do would be the # HM40975-11998 that has a connector that plugs into the back of the 7-way. The benefit to this style of connector is that it if you ever need to replace the 7-way you wouldn't have to rewire the whole thing and you could just replace the connector. If you have the round plug already all you would really need is the part # HM40975 though.

  • Running Lights Not Working With Reese Trailer Connector Adapter w/ LED Circuit Tester # 78118
  • Since you mention that the LED light on the Reese Trailer Connector Adapter, # 78118, isn't illuminating for the tail lights, it sounds like the issue is with the truck but this could be something as simple as dirt or corrosion in the 2013 Ford F-150's 7-way connector. If the pin looks clean then the issue may very likely be a blown fuse or faulty relay. If everything checks out to be fine and the running lights on your trailer still aren't functioning properly, please feel free to...

  • Parts Needed to Install Brake Controller on a 2004 Ford F-150 Heritage with 4-Way
  • The part # 37185 will convert your 4-way to a 7-way for the trailer light functions, but it would require a few more things to also function your trailer brakes. Instead of the # 37185 you would want the install harness part # 3035-P to install a Tekonsha brake controller and then the part # 118242 to convert the 4-way with a 7-way. You will also need a brake controller. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling...

  • Troubleshooting Trailer Taillights that Flicker and Turn Signals Don't Work
  • First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # 3808 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are clean...

  • Adapter Availability to Allow Both Trailer Sockets on 2012 F-350 to Be Used at One Time
  • If your truck connector looks like Hopkins # HM40975 where the two socket covers back up to one another then your options are to remove one of the covers, to use a hardwire replacement socket like # HM48470 which allows both to be used at once, or to install a 5th wheel inline plug-in wiring harness like # 50-97-410 at the back of your existing 7-way. This would let you use the existing socket for your trailer's 5-pole and provide a 7-way for your camper connection. Unfortunately there...

  • 7-Way Recommendation for a 2013 Ford Explorer to Replace 5-Way
  • A 5-way round connector like the part # PK11501 is a fairly uncommon trailer connector. I would recommend you remove that connector and replace it with a 7-way to match your trailer since that is a very popular trailer connector. For that I would recommend the part # 50-87-002. You will want to use a circuit tester like part # 3808 to test the wires to determine their function and then wire them accordingly to the 7-way.

To install a brake controller like the part # 90885 in the truck you will need the correct install harness, part # 3034-P. If the vehicle had a 7-way from the factory that is all you would need to install the controller. If instead the vehicle had a factory 4-way you would need to then make a few connections under...

  • Recommended 7 Way Wiring Harness for 2010 Ford F-150
  • To add a 7-Way trailer connector to your 2010 Ford F-150 with a factory 4-Way you will need # 37185. This is a partial hardwire installation but on your truck it will be easy. I have linked a video that should help. Go to about the 10 minute, 50 second mark and forward to see the process of accessing the additional wires to make the 7-Way fully functional. You will also need additional length of wire. Part # 10-1-1 should work to reach the wires on the truck. You may also need butt connectors...

  • Which Pin of a Trailer 7-Way is the Ground Circuit
  • Most likely your trailer has a 7-way and the reason you referred to it as a 6-way is because you didn't count the center plug. But either way I can help if you have either a 6 or 7-way. Since not all trailer connectors will use what is considered the standard wiring setup you would need to check out both of the connector diagrams I attached to determine which wire would be the ground circuit on the connector of your trailer.

  • Trailer Turn Signals and Brake Lights Not Working with a 2012 Ford F-350
  • A lot of Ford trucks use fuses and relays for the tow package wiring. Use the owners manual to locate all of the relays and fuses associated with the tow package wiring. Also, there can be tow package fuses in both the power distribution box under the hood as well as in the in-cab fuse panel. Checking fuses is easy but checking relays can be more difficult. the easiest way to test a relay is to use a known good relay in place of a potential bad one.

  • Can 12 Volt Wire from 7-Way Trailer Connector be Used as an Input on CTEK D250 Battery Charger
  • You could use the 12 volt circuit from your 7-Way trailer connector to one of the inputs on the CTEK battery charger # CTEKD250S. The inputs accept 10 to 22 volts DC power. But even if the voltage is in that range there might not be enough amperage on that 12 volt circuit for the charger to be effective (depending on what you are charging). The longer the distance the power has to travel and the smaller the wire gauge the lower the amperage will be that makes it to the charger.
