Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End

See what our Experts say about this Pollak Trailer Wiring

• Trailer Brakes Only Work when Interior Light Switch is On on Horse Trailer
  With trailer wiring, you can't make any assumptions. The wires have to be tested to determine the functions. An easy way to do this would be to use a separate 12 volt battery and apply power to each wire on the trailer and then see what turns on. Then wire up the trailer connector accordingly. There may be breakaway system that is wired in with the 12 volt circuit from the trailer connector so when the switch is off it basically closes off that circuit. That would explain why the brake...

• Replacement 7-Way Vehicle Socket for 2005 GMC Sierra
  The 7-way socket you referenced, Pollak # PK11893, connects to your vehicle with a round standard U.S. Car connector. This is an exact OEM replacement for the GMC Sierra. If you wish to have flexibility to connect to trailers that use a 4-pole flat connector you can instead consider one of the 4- and 7-way connectors shown on the link provided. These plug in to the truck in the same way but provide two connector options. Several include a length of wiring, such as Curt # HM40975, which...

• Replacement 7-Way Trailer Connector for a 2003 Chevy Silverado 2500HD
  I actually recommend that you use the Hopkins connector, # HM40975, because it comes with a 7-Way and a 4-Way and also comes with a bracket. The connection at the back is made to fit the factory harness on a 2003 Chevy Silverado that came with a factory 7-Way. I have included a link to a video that shows a typical installation for you. If you want to go with a regular 7-Way use # PK11893 and bracket # PK12711U.

• Both Turn Signals Blinking at the Same Time on Trailer Towed by 1999 Chevy Silverado
  What you are experiencing is one of the classic symptoms of an insufficient ground connection. Check that the ground connection for the trailer connector on the truck is securely grounded to clean metal. If the connection point is corroded, disconnect the ground wire and clean the metal and re attach. Do the same with the ground connection on the camper. Typically the ground connection is located on the trailer tongue. Because the vast majority of trailers use the trailer frame to complete...

• Troubleshooting Boat Trailer that Can't be Backed Up with New Truck
  Sounds like your trailer has surge brakes that have an electric reverse lock out which is supposed to allow the trailer to be backed up, but since your new truck isn't activating the solenoid that tells me that the reverse light circuit of the trailer wiring isn't active. So what you can do is run a wire from the center pin of the 7-way to tapped into your vehicles reverse light circuit and it will work like it needs to.

• Wiring Pattern for a 7-Way RV Trailer Connector on a 2001 Chevrolet Silverado Without Factory Wiring
  To install a 7-Way wiring connector at the rear of your 2001 Chevrolet Silverado without a factory 7-Way or a factory 4-Way connector, I recommend using the 7-Pole and 4-Pole Trailer Connector Socket and wiring harness, # HM40975-11998. You can the wire most of the circuits needed to the wiring harness that is located above the spare tire along the driver side frame rail. The wiring above the spare has a yellow wire for the left turn and brakes, dark green wire for the right turn and brakes,...

• Pollak 5th Wheel and Gooseneck Trailer Connector Recommendation for a 2000 Ford F350
  I spoke with my contact at Pollack and he informed that the Pollak 5th Wheel and Gooseneck Trailer Connector Wiring, part # PK11932, would be the harness that you would need for your 2000 Ford F-350. The wires of the # 12-705 should wire up color for color to the # PK11932, and as long as take your time and use plenty of electrical tape to insulate the wires after you connect them you should not have to worry about damaging any components. When I spoke with my contact at Pollack he strongly...

• Where to Find Third Brake Light Circuit for Camper Shell on a 2015 GMC Sierra 2500
  There is a dedicated brake light only wire located up under the dash and to the left of the steering column. It is with a wire bundle held together with a white tag. There should be an orange wire that is the center high mount stop lamp wire (CHMSL) that you could use. You would need to attach wire to the end of it, route it through the firewall, under the truck, and over to where it needs to go.

• 7-Way Recommendation for 2016 Chevy Silverado 3500 for Fifth Wheel
  If your 2016 Chevy Silverado has a round connector ran near the wheel well of your truck all you would need to install a 7-way would be a connector to attach to that harness. For that you would need the part # PK11893. If instead you only had a 7-way at the rear of the vehicle near the bumper you would need the part # 41157 to allow you to splice into it and install a 7-way up near the wheel well.

• Troubleshooting Right Side Trailer Lights Not Working, Left Side Working Correctly
  Most trailer wiring problems are the result of a bad ground. What I would do is start with the connectors. Maker sure the connectors on both the trailer side and vehicle side are free of dirt and corrosion and that they are properly grounded. Next, I would move on to testing the vehicle side connector using a circuit tester like # PTW2993. Since the right side is not working, you will want to test the pins of the connector for right turn and brake. If looking at the face of the connector,...

• Troubleshooting Trailer Lighting that Stops Working When Headlights are On
  Your main problem is an insufficient ground for the trailer wiring. Try improving the connection of the main ground wire of the trailer wiring harness. Make sure it is attached to a clean metal surface. Or you can run all of the trailer wires back to the main ground. This is actually the ideal solution. But you can also check the current grounds for the lights to make sure they are making a solid connection to a clean metal surface. What you described is the classic insufficient ground...

• How to Test Brake Switch to Find Circuit to Use for Brake Controller Installation
  The easiest and most reliable way to determine which wire of your brake switch wire is the correct one to use is to use a circuit tester like part # PTW2993 to test all of the wires for voltage when the brakes are applied and none when released. It sounds like you are wiring up a brake controller so I attached a help article on brake controller hardwiring for you to check out as well.

• Brackets for Installing 7-way Trailer Connector on 2004 Chevy Silverado
  To install a 7-way like part # PK11893 on that generation GM truck, we typically use a mounting bracket, part # C57202 that mounts to the crossbar of the hitch using a band clamp. Part # 18138 is used to connect the 7-way to the bracket. Many times folks are tempted just to screw the bracket directly into the crossbar of the hitch. Adding holes to or modifying the hitch in any way can weaken it structurally and will void its warranty. If there is a suitable mounting point under the bumper,...

• Availability of 7-way Round Pin to 7-way Blade RV Style Trailer Connector Adapter
  So you're needing a 7-pole round to 7-way RV (blade) style connector adapter, is that right? We don't have an adapter like that (due to the fact that the 7-way round pin connector is pretty rare these days), so the easiest thing to do would be to replace the existing 7-way round pin connector on your vehicle with a 7-way blade style connector like # PK11893 and a # PK11998 7-way pigtail. Or, if it's still needed, you could leave the existing 7-way round pin connector in place and tap the...

• Trailer Running Lights Keep Blowing Fuses when Turned On
  It sounds like there is a short circuit that is overloading the running light circuit in the tow package wiring on your tow vehicle. The most likely culprit is a dirty or corroded trailer connector on the vehicle or trailer if not both. The first thing I recommend is to make sure the truck and trailer side connectors are clean and free of corrosion inside, where the wires attach, and outside on the pins. You can also check for any damaged or pinched wires on the truck and on the trailer...

• Does 1996 Jeep Cherokee with Factory Tow Package Need a Trailer Tail Light Converter
  If the trailer connector you currently have is factory installed, you should be good to go. The signals going to that connector should already be converted, so you will not need # 119178KIT, which would be needed if the vehicle was never equipped with a trailer connector. It sounds as if you have a 7-way trailer connector, like part # PK11893 that has 6 blade-type pins with a contact in the center. You can use a circuit tester like part # PTW2993 to test the connector to ensure it is...

• Do Changes Need to be Made to Switch From Prodigy RF Brake Controller to Standard
  You should not have to make any changes to switch from the now-discontinued Prodigy RF brake controller to the factory brake controller on your 2008 Ford F-350. Of course you will not want to use the Prodigy RF's module on the front of your trailer, you will want to remove that and simply plug your trailer's 7-way into the 7-way on your 2008 Ford F-350, which will be the same plug as the Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End # PK11893.

  There is a power distribution box under the hood of the 2007 GMC Sierra that has two power posts that can be used for power to a brake controller and 12 volt power to the 7-Way RV connector at the rear of the vehicle. If your truck is equipped with a factory 7-Way and the 12 volt power circuit is not functioning you will need to check the 40 amp fuse nearest the forward most power post in the power distribution box. See photo at right. If you do not have a factory 7-Way on your vehicle...

  Sounds like you have the correct 7 way connector and the correct pins, but you are missing the wire that runs from the power posts to the connector. First let's make sure. In the under hood accessory fuse block there are two power posts on the engine side of the block.
