• Wiring a 2007 VW Eos 3.2 with Multiplexed Wiring for Towing a Trailer
• The 2007 Volkswagen Eos has a Multiplexed wiring system that requires wiring the Upgraded Heavy Duty Modulite Circuit Protected Vehicle Wiring Harness, item # C59496, for a trailer connector. There are 3 ways of wiring depending on how your vehicle is wired from the factory. In the instructions, at step 9 (see link), it explains that you may have a two wire system that requires the red stop wire to be grounded along with the white wire. If you have the 3 wire system (most likely) with amber...

• Will the Hitch Lock part # S64029 Stick Out Pretty Past Pin Hole of Hitch
• As long as the 3 inches of the hitch pin that extend beyond the pin holes of your trailer hitch do not interfere with anything you would be totally fine. This is a pretty long hitch pin lock so what you described is pretty normal for people who use it. I attached a picture we got from a customer that shows it sticking pretty far out to the side of a hitch opening.

• No Trailer Lights Using TowReady T-One Vehicle Wiring Harness for 2008 Volkswagen Jetta
• There are several potential causes for the problem you are having with the trailer lights not operating. The best method to troubleshoot is to first determine if the problem is on the vehicle side or the trailer side. You can start by disconnecting the Jetta from the trailer. Apply a circuit tester such as # PTW2993 to the pins on the vehicle 4-pole connector while a helper activates the various lighting functions one by one. Please refer to the linked photo that shows the functions carried...

• Troubleshooting Factory 7-way Trailer Connector On 2015 Volkswagen Touareg Not Having 12v Power
• From my research it looks like there is a fuse missing or blown in your 2015 Volkswagen Touareg TDI causing the 12v auxiliary power pin to not have the power needed to power your Curt Echo Wireless # C51180. I was not able to find the specific fuse, but it should be in the engine bay fuse box. It did see some reports that the 12v power pin was actually not connected any fuses, in which cause you would need to use # 10-1-1 with a 30 amp circuit breaker # PK54530 to run from the 1 o'clock...

• Troubleshooting Whistling with Rhino-Rack Vortex Roof Rack Installed
• The most common cause for the whistling you are hearing with an aero-bar roof rack installed like the Rhino-Rack # RR23QR is an open channel where the rubber inserts install. You did mention verifying that the strips are in place so this doesn't appear to be the issue. If you notice that the whistling is coming from near one of the connection points between the crossbar and mounting feet, check to make sure that the fit is secure between the two components. You can try repeating the...

• Curt Trailer Wiring Harness for 2004 Volkswagen Golf has No Left Turn Signal at the 4-Way
• The wiring system on the 2004 Volkswagen Golf is a complex system. It should have combined brake, tail, and turn signal functions on one wire. This means the red and brown wires are grounded and the yellow wire attaches to the combined brake, left turn signal, and tail light wire and green connects to the combined brake, right turn signal, and tail light wire. If this is how you have it set up and there is still no left turn signal on the output side of harness # C56175 then that indicates...

• Troubleshooting Curt Echo Brake Controller Not Working 2019 VW Tiguan and New Tear Trailer
• It is very possible that your issue is that the power wire isn't connected to a power source that can provide enough amperage and that's the problem. I would assume that the fuse for this circuit would have blown by now and the controller wouldn't even power on or show in the app. I would use a circuit tester like part # PTW2992 to test the brake output of the controller when the manual override is activated. Or you should be able to hear a click a the wheels when you do this as well...

• Troubleshooting Curt T-Connector # C56403 With Power Always On Green Wire/Right Trailer Light
• First you will want to use your Test Light # PTW2993 to test for power going into the Curt T-Connector # C56403 on your 2018 Volkswagen Tiguan. This will allow you to determine if the module is somehow getting a signal or if the module itself is defective. If you do not have power on the green wire going into the module but have power on the green wire coming out of the module you know the module is defective. If the green wire does have power you will want to check the connectors to...

• Wire Functions On LED Trailer Not Working Properly With 2004 VW Touareg V8
• I think a simple adapter may solve your problem. Since your trailer with LED lights has a 4-Way flat connector, you will need the 7-Way to 5-Way and 4-Way Trailer Adapter for VW, Audi and Porsche Towing Trailers with LED Lights # C35FR. This adapter has load resistors that provide additional power draw so the vehicle thinks there are incandescent lights on the trailer. If the adapter doesn't solve it, there is most likely a wiring issue. I've attached an article to help you troubleshoot,...

• ZCI Trailer Wiring Short on 2015 VW Golf SportWagen Causes Lights to Blink & Trailer Lights Stay On
• Based on your description of what has occurred I believe that there is a short somewhere that is causing the problems. But the converter box alone from # 119250KIT cannot be replaced by itself because it is not offered. It would require a whole new complete harness.

• Troubleshooting Install of Trailer Wiring in 2005 Volkswagen Jetta Where Stoplights Don't Work
• The problem is the red wire of the Curt trailer wiring harness part # C59236 that you referenced. This needs to be connected to a circuit that only sees voltage when the brakes are applied. This is why the kit isn't activating the brake lights like it needs to.

• Troubleshooting Air Springs Leaking on 2004 Volkswagen Passat
• I'm sure that is incredibly frustrating. It sounds like an extremely slow leak so keeping soapy water around for a few hours is really the only way to determine where the leak is taking place. Most of the time the issue is with the tubing not be cut perfectly straight using a tool like # AL10530. Sometimes scissors or other cutters can change the shape of the tubing just enough to cause a leak. I recommend securing the fittings and then using a cutter on your Firestone Coil-Rite Air...

• Troubleshooting Trailer Tail Lights That Stay On with Tekonsha ZCI Wiring Harness on 2016 Golf R
• We know from Tekonsha training on their universal-fit ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT that this item is very sensitive to the initial setup process, which must be followed exactly for correct operation. My technical contact at Tekonsha advised that the magnetic sensors in this kit are directionally sensitive. If one of these were clamped on in reversed orientation it would not function correctly. He suggested that you pull the fuse to let the circuitry power down...

• Troubleshooting Taillights for Trailer Wiring on 2012 Volkswagen Touareg
• I have attached the installation instructions for # 118668 below. I do recommend using a Circuit Tester # PTW2991 for testing your connections. This will help ensure your ground connectors are working properly as well. I do not see a black wire with green tracer coming out of the black box. The black wire is the 12V constant power. Your output wires are green for right turn/brake, yellow for left turn/brake, brown for running lights and white is ground. I hope this will help you identify...

• Troubleshooting Turn and Brake Lights not Working with Running Lights on, 2009 Volkswagen Rabbit
• With a 3 wire system: If your Rabbit has combined stop and tail lights AND has an additional tail light wire independent of the stop light wire, here is what you will need to do. Attach the red stop light wire from the harness to the combined stop and tail light circuit. Then attach the brown wire from the harness to the independent circuit. Turn signal functions will need to be tapped into at the front of the vehicle at the headlight assemblies. If the vehicle has a 2 wire system: The...

• Troubleshooting Furrion Back Up Camera Signal Issue On A 2021 Volkswagen Atlas
• Newer model vehicles transmit a signal that can cause interference between the camera and model. Furrion is currently developing a new adapter to resolve this problem. What you could do in the meantime is to hardwire the camera of your Furrion Vision S Wireless RV Backup Camera System w/ Night Vision - Rear Mount - 4.3" Screen # FOS43TASF to the 12v system of your RV battery to boost the power running to it and thus the signal.

• Troubleshooting Right Trailer Turn Signal on Trailer Wiring that Does Flash
• First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # 3808 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are clean and...

• Troubleshooting Driver and Passenger Turn Signal On Tekonsha T-One 118668 Not Working
• I would start with checking the white ground wire that got grounded to your 2014 Volkswagen Touareg, as this is a pretty common issue when a ground does not have a good connection. Make sure the ground is secured to clean corrosion free metal. Next remove both of the tail lights on your vehicle, and check that the pins inside of the connectors of the # 118668 are not bent or damaged. If all of those check out, use your circuit tester to check the yellow and green wires coming into the...

• Why Is My Roof Rack On My 2019 Volkswagen Jetta Allowing Water Inside?
• The first thing you can do, is double check the instructions and ensure that the feet are installed correctly. Something as simple as the feet being improperly spaced, or if everything is not tightened down completely, could lead to the issue you're having. If you've checked that that is all good, then you can put a strip of duct tape like # PT23ZR over the base of the foot to give it a tighter seal. However, realistically if the dealership installed this roof rack, they need to be the...

• How to Block Entry of Water Into 2011 Volkswagen Golf Equipped with SportRack SR1010
• Semi-custom roof racks like the SportRack # SR1010 are designed to be cost-effective and to fit reasonably well on lots of different vehicles so in some instances the fit may not be quite as good as with a custom rack meant just for your particular car. But we can help you with your leakage issue. I suggest you apply some weather-stripping tape like # WS1412 or # WS1434 to the area where you're finding moisture entering the car. This self-adhesive type of foam tape is springy and should...
