• Trailer Lights Stay on Once Vehicle Ignition is Shut Off
  I suspect your problem is caused by a damaged or corroded trailer connector. Take a look at your trailer connectors, both the socket on your truck as well as the plug on the trailer. Look for green or white corrosion on the pins or sockets of the connectors. If corrosion is visible, there is a strong possibility that the corrosion has spread to the interior of the connector. The terminals that each individual circuit connects to are very close together, if corrosion builds up on the terminals,...

• Adding a 7-Way Trailer Connector and Electric Brake Controller to 2011 Jeep Wrangler Unlimited
  Since your 2011 Jeep Wrangler Unlimited has the factory tow package there should be a square plug for the Pollak # HM40975-11933 to plug into. This will work well to supply a 7-way trailer connector. If you need to run wiring to install a brake controller use # 5506. If you don't have the square connector you'll first need to add a 4-way using # 118416 and then convert that 4-way to a 7-way using our # ETBC7 kit. This includes the 7-way and everything you need for an electric brake...

• Where is the Running Light Fuse for Trailer on 2013 Ram 1500
  From what I could find, the fuse is in the underhood fuse box next to the battery. Check the yellow 20 Amp fuse in location F29. That should be for the trailer running/parking lights. If I were you, then I would also check the Pink 30 Amp fuse in location F30. That is for the trailer connector itself, so it wouldn't hurt to make sure it is okay as well. There is also a 15 Amp Blue fuse in location F79 for your truck's clearance lights. This fuse shouldn't have any bearing on the trailer's...

• Locating OEM Plug for 7-Way on 2022 Ram 5500 Cab and Chassis
  The OEM plug that would allow you to use the # HM40975-11933 should be found at the rear of your 2022 Ram 5500. Everything indicates that your truck has the rectangular factory plug that would allow you to use this wiring harness. Typically this would be found behind a cover for the 7-way but I don't have an exact location for a 5500 cab and chassis. If you still can't find it you could check for a brake controller port. This would have the brake output wire that runs back to the 7-way...

• How To Install a 7-Way Trailer Connector On a 2004 Dodge Ram 1500
  Yes, it is very possible to install/fit a 7-way trailer connector on a 2004 Dodge Ram 1500. I first recommend looking under the vehicle for a square ten pin connector. This (if present) will be located behind the rear bumper near the spare tire and will match the end of the 7- and 4-Pole Trailer Connector Socket part # HM40975-11933 which is what I recommend using if this connector is present. If you don't have the above square ten pin connector then you will need to start with a 4-way,...

• Replacement 7-Way/Wiring Harness for 1998 Dodge Ram 2500
  If your 7-way was factory installed (you can tell by looking for the Mopar logo of the cover for the 7-way), it will have the rectangular connector used by the # PK11933 which would plug into the factory connector. For a replacement 7-way connector, use part # PK11893, or as an alternative that includes a 4-pole connector, you could use # HM40975-11933 which includes the 7-way as well as the # PK11933 harness and a mounting bracket.

• How to Install 7-Way Connector on 2005 Dodge Ram 1500 with Factory 4-Way
  I do have a solution for you, but the # HM40975-11933 will not work since your 2005 Dodge Ram Pickup did not come with a factory 7-Way trailer connector. If what you're looking to do is upgrade your factory 4-Pole connector to a fully functioning 7-way, then what you need is the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation # ETBC7. This will allow you to run your brake output, reverse light and 12V power wires, which aren't pre-wired from the factory on your truck.

• Adding a 7-Way to Bumper and Bed of a 2012 Ram 2500 that Originally Came with a 7-Way
  Usually when there is a question on the function of a wire the solution is to test that wire. But you indicated that you have tested the wires and still cannot figure out the functions. But you didn't say why that is. Were you getting conflicting readings from the meter? A meter might be a little too sensitive for this test. Really all that is needed is a circuit tester such as # PTW2993. Two of the wires will show power when the brake pedal is pressed. And one of those wires will also...

• Which 7-Way Trailer Connector Fits a 2007 Dodge Ram with Factory Tow Package
  The Pollak Custom Fit Vehicle Wiring, # HM40975-11933, will fit your 2007 Dodge Ram, but will need to be mounted using the included bracket to a location under the bumper.

• Replacement Trailer Connector for 2007 Dodge Ram Cab and Chassis and How to Wire in Camper Lights
  First, if your 2007 Dodge Ram cab and chassis model came with a factory installed 4/7-Way then you can use # HM40975-11933 to replace it. It plugs into the factory wiring harness under the truck. What I would do is to wire the camper light wires to either a trailer side 4-Way or 7-Way connector, depending on what all functions are needed, and plug that into the trucks trailer connector instead of hardwiring it in. For a 4-Way you can use # HM48110. White is ground, brow is running lights,...

• No Power to 12 Volt on 7-Way of 2020 Ram 3500
  It is very likely the fuse if you are not getting the 12 volt auxiliary power at the 7-way of your 2020 Ram 3500, so you'll want to check your owner's manual to see where that fuse is located or your local Ram dealer can tell you. If it's not the fuse then it is going to be your 7-way connector so you'll want to use Circuit Tester # PTW2979 to check the 12 volt wire going into the 7-way connector at the plug, and behind where the 7-way plugs into the factory wiring. If there is no power...
