• Troubleshooting No Power on 12V Wire for Brake Controller on 2004 Volkswagen Touareg
• Aside from trying to swap out the fuse for the 12V wire with one that you know is good, the only other thing I can really offer is to route some 10 Gauge Wire # 10-1-1 from your battery through a 20A Circuit Breaker # PK54520 and then splice it into the 12V wire for a brake controller on your 2004 Volkswagen Touareg using Butt Connectors # DW05745-5. This will bypass all of your OEM wiring and will get you that 12V power you are needing. I have attached a diagram of how you would hardwire...

• Trailer Signal Lights Malfunctioning After Installing Optronics Tail Light
• From what I can see in your question, it seems like the most likely cause for the signal lights on your trailer to be malfunctioning after installing the Optronics Sealed Stop, Turn and Tail Light # STL78RB is the ground connection on your trailer. You mentioned grounding the white wire from the new light to the metal body of the door hinges. I strongly recommend finding a more suitable ground on the main trailer frame for this wire. A weak or bad ground can certainly lead to many different...

• Troubleshooting Curt Echo Trailer Brake Controller Not Comin On 2011 VW Touareg
• I sounds like you may not have power going to the charge line circuit on the 7-way for your 2011 Volkswagen Touareg. You can use a Test Light # PTW2993 in your junction box to ensure you are getting power from your charge line on the 7-way. You will need to test it at the junction box(remove 7-way wire from trailer battery connector) since your Touareg has the smart trailer wiring. The Curt Echo # C51180 receives its power from the charge line which does not send power to your trailer lights....

• 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 Brakes that Only Lock Up When Powered Straight From a Battery
• What gauge wire do you have run to your brake assemblies? If it's thinner than 10 gauge you might want to try upgrading the wiring. We sell it by the foot, part # 10-1-1. Since the brakes seem to work when operated straight from a vehicle battery (which will have more amperage than a controller), but not from a brake controller it almost sounds like your brake magnets could be weak or the grounds/wiring isn't quite sufficient. Try testing the brake magnets. I attached an FAQ on how this...

• Trailer Brake Controller Shows 3.5 Volts Output with No Trailer Connected
• If no trailer is connected and you test the brake pin on the 7-Way, there should be only be a tiny amount of voltage because that is how the controller senses if there is a trailer. But 3.5 volts sounds too high. If this is occurring without the brake or manual override engaged then there is something drawing power on the blue wire (short to blue wire). If this happens when you use the manual override, then the power sent back will only go as high as it is set. To determine if the brake...

• Troubleshooting BackUp Sensors Bulb Out Message with Bully LED Hitch-Mounted Step On VW Touareg
• It sounds like your back up sensors deactivate when you plug in trailer wiring. This would be to prevent the sensors from going off all the time while in reverse because of them detecting the trailer behind you. The best solution I can provide would be to install a second 4-way that bypasses the factory one of your 2014 Volkswagen Touareg. For that you would want the part # 118668. The error message you are receiving is a common problem on German vehicles when they are connected to a...

• 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...

• Trailer Wiring Harness Shows No Power After Installation on a 2007 Volkswagen Touareg
• Trailer wiring harness # 118509 is a powered converter that requires a direct connection to the vehicle battery. If you did not make the connection to the battery or the fuse is missing or blown then it would not show any power on any of the circuits (when activated). If the connection to the battery is good and the fuse is inserted then check the ground connections (white wire). It must be attached to a clean and corrosion free bare metal surface. No paint or anything. And it works best...

• Furrion FR74FR 7-Way Power Adapter for Vision S Camera System
• The easiest way to see if the # FR87PR adapter will work for you is to use a multimeter like # PT89ZR on the running lamp pin on your 7-way (pin in the 11:00 position) while the running lamps are switched on. If there isn't at least 300mA coming from that pin, then in that case the # FR87PR would fix your problem. If you're getting enough power on that pin, then something else is causing the issue. I'd recommend ensuring that the antennas are fully screwed in. If they are, try repositioning...

• 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,...

• Curt Triflex Brake Controller Always On Installed in a 2006 Volkswagen Touareg
• Installation of a brake controller on a 2006 Volkswagen Touareg is a little more complicated than on many other vehicles. It requires some special parts from Volkswagen and you will likely need a 12 volt normally open relay to avoid erratic displays and trailer braking problems. I have included a link to a help article detailing the process. It is critical that it is followed exactly. I know this method works with Tekonsha controllers like the P2 # 90885 and P3 # 90195. I cannot confirm...

• 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...

• Troubleshooting SH Error Code of Tekonsha Prodigy P2
• The SH code on the Prodigy Brake Controller, # 90885, indicates that while idle, the brake controller is sensing a short in the brake wire. Most likely this is due to corrosion on the trailer connector pins so I would recommend cleaning them to see if that helps. If that doesn't fix it you need to look for cut or exposed wire on this circuit most likely on the trailer side of the wiring and clean up as needed. If it's blank now check under the hood for the fuse or relay associated with...

• Troubleshooting Trailer Wiring Kit On a 2011 Volkswagen Touareg that Blew Fuse and Stopped Working
• What you will want to do is test the wires going into the box of the converter box for voltage with a circuit tester like the # PTW2993 to see if there is voltage going into the box when the taillight functions of your vehicle are applied, and then test the output side of the box to see if the current is making it through the converter. If not then the problem is that the converter box has shorted itself out and would need to be replaced. Before you replace it you will want to inspect...

• Troubleshooting Issues with 2012 VW Touareg 7 Pin Trailer Connector
• If your trailer or tester utilize LED lights that is likely the issue. The factory 7-way on your 2012 VW Touareg wasn't designed to function with LED's without the adapter # C57003 which has integrated load resistors to allow LED's to not trigger lamp out sensors. This also helps with the emergency flashers. If your trailer and tester are not LED, then you may have an internal issue with your 7-way and you can use either # A10-7072VP or # HM40975 to replace it. Before replacing, I...

• Why Wouldnt Curt Echo Mobile Brake Controller Power On When Plugged into 7-Way
• Yes, since the Curt Mobile Echo part # C51180 is not powering on that would indicate that the 12 volt accessory circuit is not active on the 7-way. It's actually pretty common that this circuit isn't active so what you will need to do is run 10 gauge wire like part # 10-1-1 through a breaker like part # 9510 and you'd be set.

• Testing 7-Way Socket on 2015 VW Touareg for Active Trailer Lighting & Power Circuits
• A 7-way trailer socket like # 37185 on a vehicle includes a 12V auxiliary trailer power circuit that is intended to maintain a charged battery installed on the trailer while you drive. This power feed cannot charge a depleted battery but it can maintain one that is already well-charged. If you refer to the linked photo of a 7-way vehicle socket you will note this circuit is carried on the pin at the 1-o-clock position as you view the socket. Some vehicle electrical systems will have this...
