• Wiring Needed To Use Rampage Light Strip On 2012 Toyota Tundra
  The Rampage SuperBrite LED Tailgate Light Bar part # RA960134 does connect to a 4-pole flat trailer connector on the Tundra. For that I recommend Curt T-Connector Vehicle Wiring Harness for Factory Tow Package part # C55774 which will allow you to plug into the factory tow port under the bumper and gives you a 7-way plug and a 4-pole flat to plug your light strip part # RA960134 into. You can use both the 4-pole and 7-way functions at the same time as long as you don't overload the circuit...

• Towing Capacity and Parts Needed to Tow Trailer with 2015 Jeep Grand Cherokee
  I was able to track down the online owner's manual for your 2015 Jeep Grand Cherokee Overland and for this vehicle you are looking at a maximum trailer weight of 6,200 pounds if you have the 3.6L engine or 7,200 pounds if you have the 5.7L engine. In either case you will still have a healthy safety margin between the loaded weight of the Nomad 186B Trailer and your Jeep's limits. I do still recommend verifying this information in your copy of the manual or by checking with a local Jeep...

• Troubleshooting Lost Power on 7-Way Trailer Connector on 2018 Ram 1500
  I'd start by making sure that your 7 way didn't get disconnected from the US car connector it's plugged into. If a fuse was blown, it would normally only effect the circuit that it's tied to, so I don't believe that would be the cause of your issue. For everything to completely shut off would lead me to believe that something has either become loose or disconnected completely. If that isn't the case, it might be possible that something overloaded the 7 way connector and fried it. You...

• Parts Needed to Add 7 Way Connector to 2013 Ford F-150 XL
  It sounds like you may already have the factory towing package wiring present, so to install a 7 way connector on your 2013 Ford F-150 XL you can use the Curt # C55774, which will plug into the same port your 4 way is plugged into. I do recommend checking to make sure that you've got a round, US Car connector port there that your 4 way is plugged into to determine if this will be compatible. If you don't have that connector it means that your 4 way was added after purchase. If that's the...

• Replacing 6-Way of 2014 Chevy Silverado for 7-way
  From the factory your 2014 Chevy Silverado should have came with a factory 7-way and not a 6-way so most likely your 7-way was swapped out for a 6-way. To then swap a 7-way back in we have the # A10-7072VP listed as a fit or if you want the style of 7-way and 4-way like a lot of Silverados came with you'd want the part # HM40975. I attached an install video for this on a similar 2015 Silverado for you to check out as well.

• Fuse and Relay Locations for Trailer Lights on a 2008 Ford Super Duty
  Starting on page 303 of the owner's manual for a 2008 Ford Super Duty it looks like there are relays in positions 20 and 21 for the left and right stop/turn trailer signals. Then on page 305 there is a fuse in position 34 for the stop/turn relay and in position 42 there is a fuse for the park lamp (running lights) relay. Page 306 shows a relay in position 55 for the park lamps and a fuse in position 63 for the back-up lamps as well. Let me know if you are still having problems and I can...

• Will Installation of Curt 7-Way on 2012 Jeep Grand Cherokee Require Computer Flash
  It is possible the wiring is already active on your 2012 Jeep Grand Cherokee, but you won't know until you install the # C55774. Once installed, test the connection to see if it is working. If not, you will need to go to the dealer and have them re-flash the computer to activate the tow package wiring circuit.

• Troubleshooting Trailer Turn Signals and Reverse Circuits on 2013 Ford F350
  If the fuses aren't blown, there could be some corrosion in the trailer connector on the truck preventing the signal from getting through. If you can see green or white corrosion on the pins, there's a chance the corrosion has spread to the interior of the connector and damaging it. Try testing the wires feeding the connector itself to ensure that power is reaching the connector when the turn signals are activated, which would confirm or rule out the connector as being the problem. If power...

• Fixing Factory Trailer Wiring On 2004 Nissan Titan That Has Been Cut Off
  Depending on how far they cut back at the factory tow package, you may be able to just a 7-Way plug like part # C55774. If they just cut off the 7-way plug but not the OEM connector port under the bumper this will work. I have attached a photo of what you will need to look for. You did say that your truck came with a factory wiring harness but if you do not have the two relays behind the panel on your dash board to the left of your steering wheel then you will need to add those from the...

• Adding a 7-Way Trailer Connector to a 2015 Ford Expedition
  First check under your 2015 Ford Expedition for a round connector, perhaps in the vicinity of the frame rail or spare tire, that could plug into the round connector on 4- and 7-Way # C55774. If that connector is present under the vehicle then you just have to plug it into the 20119 and then mount the connector. If you do not have that connector but have a 4-Way then you will have to hardwire in the 7-Way and brake controller using # ETBC7.

• No Power At OEM Trailer Connector On A 2013 Jeep GC Laredo
  I would start by inspecting your connector for corrosion or debris that could affect your connection points. If they need cleaned, I would give that a go and try the connector again. Next, I would check your ground connections for corrosion, stacked rings, or if it's loosely mounted. A wire brush, reset or tightening down would be in order. If that has not helped, using a circuit tester like # PTW2993 to test the pins on the connector where the wiring harness plugs into the truck is...

• Adding a 6- and 4-Way or 7- and 4-Way Trailer Connector to a 2004 Ford F-150 Crew Cab 4x4
  The instructions for Curt 6-Way Round and 4-Flat Connectors # C55664 is listed only for certain GM vehicles and some imports (see instructions link for the list) but not for a 2004 Ford F-150. However, it should still work because it has the same connector to plug into the factory harness as # C55774 which is a 7- and 4-Way that is listed as a fit for a 2004 Ford F-150 that came with a factory 7-Way. If your truck came with a 4-Way then you would not be able to use either connector but...

• Replacement OEM 7-Way Connector w/ a 4-Way
  Yes, you can. Both the Curt T-Connector item # C55774 and the Mighty Cord Replacement 7-Way item # A10-7072VP use the USCAR 7-way socket. These are what every vehicle that comes from the factory with a 7-way connector has. Since your 2023 GMC Canyon came from the factory with a 7-way connector, you can use the Curt item # C55774 to replace your broken one. This will provide you with both a 7-way and a 4-way. I have linked an installation video below.

• Is the 7-Way for a 2010 Ford F-250 Different Than One for a 2011 Ford Ford F-250
  Most newer vehicles utilize what is called a USCAR connector which is essentially an industry standard pinout for trailer connectors. Therefore, so long as you have the USCAR connector you can use pretty much any 7-way. This will be the case for a 2010 Ford F-250 and a 2011 Ford Ford F-250. For example, a bumper 7-way like the Curt T-Connector Vehicle Wiring Harness part # C55774 will fit both a 2010 Ford F-250 and a 2011 Ford Ford F-250 as will an in-bed 7-way like the Curt 5th Wheel/Gooseneck...

• Installing Brake Controller on Farm Tractor For Moving Trailer Around
  I'd be happy to help you with that. Since it's a tractor, there's likely a few differences from what would be seen on a standard passenger vehicle. You very likely won't need to contend with turn signals and taillilghts, and you won't be traveling at highway speeds or speeds typically seen on-road, so the installation will be somewhat simplified. For a brake controller, a simple and inexpensive time delayed controller like the Tekonsha Power Trac, part # 39523 would work well. The controller...

• Trailer Hitch and Towing Accessories for 2017 Ford Flex with Dual Exhaust
  For the dual exhaust-equipped Flex, you'll want to use the Curt Class III, part # C13110, as the # 13551 isn't a fit for models with a dual exhaust. If you'll be towing with your hitch, you'll also need a trailer wiring harness like part # C55774, a ball mount like # 40346 used in the rise position, a pin and clip like # PC3 and a trailer ball. For a 1-7/8 inch ball, use # 19260 or # 63845 for a 2 inch ball.

• How to Easily Install 7-Way on 2018 Ford F-150 that Has 4-Way
  The wires are ran to the rear of your 2018 Ford F-150 that you'll need to wire up a 7-way but they stop at a connector that's in the frame rail of the truck. So the adapter you need is the part # 37185 which your 4-way will plug into and then depending on what 7-way functions you need will determine how much of the truck's wiring in the truck frame you'll need to access. The blue wire of the adapter would need to run to the blue wire pointed out in the harness if you have a brake controller,...

• Recommended Trailer Wiring Harness For 2015 Jeep Grand Cherokee With Factory Tow Package

• Replacement 7-Way Trailer Connector for a 2003 Chevy Silverado
  The 7-Way trailer connector on the back of your 2003 Chevy Silverado should have a round plug behind it that plugs into another harness that continues up to the front of the truck.

Or you could use # PK11916 that you referenced if you just want the 7-Way. Both options are assuming none of the wiring was damaged. You can use a circuit tester like # PTW2979...
