  • No Function on any Right Side Lights on Trailer Behind 2010 Subaru Forester
  • I have found the best way to find a bug in an electrical system is by process of elimination. Eliminating possible sources will eventually lead to the right spot. First thing I would do, is check the 4-Way connector on your Subaru Forester. Using a circuit tester like part # PTW2993 or a 4-Way tester like part # F5CT or part # I26. The white wire is ground, the yellow wire is left turn and brake, the green wire is right turn and brake, and the brown wire is taillights. Chances are, the...

  • Trailer Lights Do Not Light Up When Connected to 2007 Subaru Outback with Working Wiring Harness
  • Since the new wiring harness on your 2007 Subaru Outback has power the issue must be on the trailer side. It does sound like a ground issue. There are numerous grounds on a trailer so there are a few places to check. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free...

  • Troubleshooting 2011 Subaru Forester Tekonsha T-One Wiring Harness
  • The T-One Vehicle Wiring Harness # 118467 for your 2011 Subaru Forester has a mini fuse you might want to start off checking to ensure the module is getting power, and then there is also a fuse (I believe in position 1 of your fuse box but you need to verify that on your end) on your Forester that would be worth checking to make sure it is in good shape to send power back to the trailer light functions. Aside from that the next best thing is to test the various pins for light and power...

  • Troubleshooting Running Light Not Working On 2011 Subaru Outback Trailer Connection
  • It sounds as though there may be a damaged pin connector in the wiring. I recommend going to the connector on the 2011 Subaru Outback where the Curt T-Connector Vehicle Wiring Harness # C56040 connects. Pull apart this connection and check to ensure that all he pins on the harness are securely in place. You can also check the voltage coming into the connector to ensure that there is not something wrong with the fuses or wiring on your Outback.

  • Troubleshooting Hoppy Trailer Harness Part 33855 on a 2001 Subaru Forester
  • Use a circuit tester and go to the plug on the vehicle that you connected the harness to. Disconnect the trailer harness. Look at the picture I have linked below. In the picture, the pin on the top left corner should be the left blinker pin. Test this pin on the vehicle connector. Have someone activate the left blinker. If your circuit tester flashes with the blinker, then the Hoppy harness is probably bad. If your circuit tester does not flash, then there is a problem on the vehicle....

  • Trailer Lights on 2 Different Trailers Do Not Work When Connected to a 1999 Subaru Forester
  • It is possible that there is an in-line fuse somewhere back from the 4-Way end on your 1999 Subaru Forester. You will need to follow the wiring back as far as you can to determine if there is indeed a fuse. If you cannot find one, then consult the vehicle owner's manual for all of the fuses/relays in the vehicle associated with the wiring harness. Some vehicles have wiring fuses under the hood and inside the in-cab fuse panel. If you have an aftermarket harness like # 33855 then you can...

  • Troubleshooting Jensen Stereo LED Display Faintly Lit When Powered Off
  • More than likely the dimly lit display you're seeing is from the voltage taking a while to dissipate. It doesn't take much power for the LED display to show up. Give it a few hours and check again to see if it is still lit. Even if it is, the power draw isn't enough to drain your battery. It may also be from the separate power wire running from the battery to the stereo system for memory. This small amount of power allows your AWM965 to keep the settings, just like the stereo in your...

  • Brake Controller Install - 2019 Subaru Crosstrek Causing Traction Control/Hill Assist Warning Lights
  • I suspect you're using the incorrect wire from the brake switch. According to the information I've found, the circuit you're wanting to tap the red brake controller wire into is a white/brown striped wire, not a solid brown. Once you tap the red controller wire into that circuit, everything should work fine for you. The wire you're looking for should show power only with the brake pedal pressed.

  • Troubleshooting Toad Wiring on 2017 Subaru Crosstrek with 3 Wire System
  • The Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 was a great choice for your 2017 Subaru Crosstrek. You did have a connection mistake as the amber blinkers should not be lighting up when the brakes are applied. You simply connected the wrong vehicle wire to the diode. You want to tap into the tail light wire with that diode and not the turn signal wire as the system coming from your motorhome will have the brake and turn signals combined. Your vehicle has a 3...

  • Fixing Excessive Sway when Using Curt Trailer Hitch 13390 on a 2012 Subaru Outback
  • I am not sure what you mean. The hitch itself should not be swaying at all. If you are talking about trailer sway while towing then the aerodynamic differences between the vehicles could the reason for the trailer to sway more with one vehicle than another. You would only need a friction sway bar, # 83660, and ball mount bracket # RP26003 for 2 inch hitches to stop the sway. If you have a bike rack or cargo carrier with excessive movement then a simple anti-rattle device such as # MPG908...

  • Where is My Connector Plug on My 2022 Subaru Outback Wagon?
  • As far as the harness, based on your recent searches, I believe you are referring to the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Connector # HM11143885 for your 2022 Subaru Outback. I confirmed with my research that the plug is located under the rear trim panel on the passenger side, just inside the rear storage compartment on your 2022 Subaru Outback. I went ahead and attached a video that shows where the plug is located using another 4-way wiring harness. The installer...

  • Will RAB be Disabled When Installing Trailer Hitch on 2019 Subaru Ascent
  • I took a look at the online owner's manual for a 2019 Subaru Ascent and it looks like the Reverse Automatic Braking System (RAB) can be disabled if the rear bumper has been removed and then reattached, which is what is required when installing the Draw-Tite Max-Frame Trailer Hitch # 76253 on a '19 Ascent as opposed to a hitch like the Curt # C13400 which sits under the bumper.

  • Left Trailer Taillight Malfunctions When Headlights Are Switched On
  • What you describe is a classic symptom of a poor ground connection. Everything works fine, until the vehicle headlights or running lights are switched on. When this happens, the maximum amperage load is being drawn which is when a ground problem rears its ugly head. You'll want to check the ground connection for the trailer connector on the tow vehicle, the main ground on the trailer tongue and the ground connection for each of the trailer taillights. Make sure the ground connection is...

  • Troubleshooting Trailer LED Lights Staying on With Vehicle Off
  • It sounds like you're needing to install the Load Resistor Kit # DI34ZR so the Hopkins Wiring Kit # HM11143885 on your 2016 Subaru Outback Wagon is able to read the trailer lighting system properly. What these basically do is pull a little more power for the trailer lights which makes it easier for the vehicle to recognize the trailer is connected. I recommend installing the resistors closer to the trailer connector rather than the lights so you don't have to get a resistor for each individual...

  • Trailer Turn Signals Not Working After Installing Curt Wiring Harness in a 2013 Subaru Impreza
  • You can test Curt trailer wiring harness # 56061 on your 2013 Subaru Impreza to determine if the converter is faulty. The first step is to test the wires leading into the converter box from the vehicle using a circuit tester such as # PTW2993 or a meter if you have one. Have someone sit in the vehicle and go through the lighting functions while testing the input wires on the converter. If everything works as normal on the input side, then move on to testing the output side (4-Way end)....

  • Trailer Connector Has Current All The Time After Being Moved From 2000 To 2006 Subaru Outback Wagon
  • The Tow Ready Custom Fit Vehicle Wiring, part # 118461 is designed to fit both the 2000 and 2006 Outback Wagon as long as it is not a Sport model. After connecting the T-One harness you should not show any current on any of the pins unless they are activated like stepping on the brake or using the turn signals. If you have all of the connections secure and the key is off and you are showing current on one of the trailer connector pins, there is probably a short in one of the circuits of...

  • Troubleshooting Wiring on a Trailer with Separate Brake and Turn Signal Lights
  • There are two things that may help to solve your predicament. The easier one is the converter. The converter that you used, part # 118158, is not compatible with LED lights. So, even if the wires all lined up where they needed to go, it wouldn't have worked anyway. We don't currently carry a 2-to-3 converter compatible with LEDs. As for the wiring, that's a little harder to figure out. From what I can tell, you might be using a wishbone 4-way harness on your trailer. These differ from...

  • Why Is The Draw-Tite Trailer Hitch DR73RR Not Fitting My 2020 Subaru Outback Wagon?
  • I would be happy to help! The Draw-Tite Trailer Hitch Receiver # DT73RR you ordered through us is a confirmed fit for your 2020 Subaru Outback Wagon. Due to the size and weight of hitches it is not uncommon for the mounting flanges to get flexed during shipping causing some weird fitment issues like you are having. What you will need to do is follow the included help article that goes over identifying exactly how much your hitch flexed and how to correct it. I also included a video...

  • Replacement Water Lines and Fresh Water Inlet for Pop Up Camper
  • We do have water inlet fittings, like the Valterra Water Inlet for RVs # A01-0176LFVP, that would replace the entry fitting on the outside of your pop up camper if you decide to replace that fitting. To replace the water lines inside/under your camper, typically PEX pipes and fittings are used to make those connections. We do not have these available for purchase, but they are usually available at your local hardware store.
