• Parts Needed To Add Hopkins 7/4 Pole Connector To a 2020 Ford F-150 With Factory 4-Way
  I have a couple ways you can install the 7- and 4-Pole Trailer Connector Socket # HM40975 on your 2020 Ford F-150 with a 4-way flat factory connector. The first is going to be the easiest but is more costly. You will use the harness from the Curt 7-Way # C56413 and connect to the connector you found. The Curt harness will connect to the factory wiring as seen in the installation video I have linked near the bottom of the page. Otherwise we do have the Hard Wire Connector # 20147 which...

• How to Activate the Factory Trailer Towing Package on a 2000 Chevy Silverado
  The wiring will already be run on your 2000 Chevy Silverado. There will be 1 of 2 wiring situations on your truck. The wiring for the 7-Way will be located above the spare tire. If it is just bare wires with no plug, you will need to hard wire one in. The harness we have for this wiring situation is Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket, # PK11898. If your truck has a plug, then you will need to use a connector like the Replacement Multi-Tow...

• 7-Way Wiring Configuration for Slide-In Truck Camper
  Your slide-in truck camper does not have electric brakes so the blue brake circuit wire from its 7-way connector is not used. All other lighting functions as well as 12V auxiliary power will be maintained on the other circuits. Please refer to the linked photo for the standard wiring/function configuration for RV-style 7-way connectors.

• Installing 7-Way and 4-Way Connectors on a 2015 GMC Acadia
  The Hopkins # HM40975 that you referenced plugs into a US Car Connector (see attached picture). This typically will replace a factory 7-Way on a vehicle so if your 2015 GMC Acadia didn't come with a 7-Way you might not have that connector. If it does exist though it will be located somewhere around the trailer hitch. If you don't have the US Car Connector but you would like fully functioning 7-Way and 4-Way connectors then we do have a solution for you. Simpy install the T-One Vehicle...

• Recommended Trailer Hitch for a 2020 Ford Ranger
  The trailer hitch that I recommend for a 2020 Ford Ranger is the Curt Trailer Hitch Receiver part # C13417 which is a custom bolt-on fit that does not require any cutting or drilling. The process should actually only take you around 20 to 40 minutes. I have attached an install photo for you as well. For a trailer wiring harness, the T-One Vehicle Wiring Harness part # 22124 is your best option as it does not require any splicing therefore is almost entirely plug and play. I also recommend...

• Is There a Difference Between Hopkins 7 and 4-Way Kits 40974 and 40975
  Basically they are the same connector with just a slightly different part number. We carry the part # HM40975 and if you ordered the 40974 from someone else (not recommended haha) you'd get the same thing which just a different part number on the box. I attached an install video for this kit for you to check out as well.

• Troubleshooting Danger Notification and No LED Light on Curt Echo Brake Controller
  Sine the LED does not light up on your Curt Echo # C51180, that means there's no power getting through to it. Given the fact that the Echo was receiving power and working properly at one point, chances are you're dealing with a poor ground issue. I would start by checking the power and ground circuits on your Ram's trailer wiring. These will be on the 1 o'clock and 7 o'clock positions, as shown in the attached diagram. You can use a 12V probe-style circuit tester, like # PTW2991 to check...

• Installing a 7-Way Trailer Connector on a 2013 Ford E-250 Van
  I checked with Tow Ready about 7-Way connector # 118261 and it is not a confirmed fit for the 2013 Ford E-250 van. Since there are no other options and since you have some factory wiring already, I recommend using 4 and 7-Way connector # HM40975 with harness # PK11998. You will need to test the wiring on the vehicle end with a circuit tester such as # PTW2993 to determine the functions. Then you can install the harness accordingly: Red - Left Turn and Stop White - Ground Blue - Electric...

• How Does Trailer 12 Volt Accessory Circuit of 2019 Ford F-150 7-Way Activate
  The 12 volt accessory circuit on your 2019 Ford F-150 activates in a pretty unique way. You first have to connect the trailer to the truck and then using the dash display let the truck recognize the trailer. Also once this is done the circuit is still only active when the vehicle is in drive. Or you could bypass all of that and run your own wire for this circuit with 10 gauge wire like part # 10-1-1 (sold by foot) through a breaker from the positive battery post to the 1:00 pin of the 7-way.

• Troubleshooting Electric Trailer Brake System on Trailer Towed by Chevy 2500 Series Truck
  Discovering why the trailer brakes are not getting power will be a process of elimination. I am not aware of what you have and have not checked, so I will describe the whole troubleshoot process. Start with the brake controller itself. Is it properly adjusted and leveled (if necessary) according to the instructions? Is it getting power? To determine if the controller is receiving power, you can use a circuit tester like part # PTW2993 on the black wire that feeds the controller to ensure...

• Location of Factory Wiring Connector for 2021 Ford Explorer Limited
  Hello Ken; what wiring harness are you trying to install? Do you have the factory tow package on your 2021 Ford Explorer? If you don't have the factory tow package there won't be a wiring connector at the rear of the vehicle. If you have the factory tow package there will be a plug behind the bumper that attaches to the # HM40975. If you do not have the factory tow package you need to install the Curt 4-way # C56093 which plugs into the connection points in the rear cargo area as seen...

Then, you will want to check the wiring on the trailer, start at the 4-way connector and visually inspect the wires for any cut or exposed wiring.

• Troubleshooting Damaged Trailer Wiring Connector on 2002 Ford F-350
  If the in-bed 7-Way on your 2002 Ford F-350 was damaged then you likely need to replace the entire wiring harness with something like the Hopkins # 41157. It would be best to inspect the connectors for any damage as well. As far as fuses go, if you turn to page 162 in your copy of the owner's manual you should see that the fuses in locations 6, 38, 101, 115, and 305 are for the various trailer functions. Aside from this if you're still having issues you'd need to take your pickup to a...

• Parts Needed to Add 7-Way to 2017 Jeep Wrangler with 4-Way
  Hey Chester, to convert the 4-way of your 2017 Jeep Wrangler to a 7-way you would want the part # 37185 unless the trailer has brakes. If the trailer does have brakes you'd instead need the part # ETBC7 with a brake controller like the P2 part # 90885. There isn't a direct plug in 7-way option that fits your Wrangler unless it came with a 7-way already.

• Troubleshooting GMC Truck that Left Turn Signal on 7-Way Stopped Functioning
  Since you have isolated the problem down to the left turn signal on the 7-way on your vehicle the problem is most likely a blown fuse under the hood of your 2006 GMC Sierra 3500. GM vehicles tend to blow fuses easier than the other manufacturers. Check the fuse box under the hood of your engine on the driver side for the trailer related circuits and replace as needed. I attached a couple help articles for you to check out as well.
