Installing the Curt Powered Wiring Harness # C56200KIT on a 2009 Mercedes-Benz C300
I do have some information that will help you install the Curt PWM Powered Wiring Harness, # C56200KIT, but it is important to remember to test each of the wires using a circuit tester, like the Quickee Tester # 3808, before cutting or splicing into your vehicles wires. According to my contact at Curt you will see 7 wires in a row on the back of the driver side and passenger side tail light assemblies. The wire colors and functions are as follows - Driver Side Brown Wire - Ground Black

Finding the Running Light Wire to Install Trailer Wiring Harness on a 2004 Volvo XC70
If the running lights are on all the time, even the rear tail lights, then it should be easy to find the one wire that is hot all the time. So what you would do is basically find the wire you think it might be when the vehicle is on. Then turn the vehicle off and remove the key. If the tester also goes off when the car goes off but comes back on when the car comes on then that must be the running light circuit. You can use the video I have linked as a guide. It is on a 2011 Volvo XC70 so the

Can you Route a 4-Way Trailer Connector Under the Vehicle on a 2009 Volvo XC70
Many vehicles will have grommets somewhere in the rear cargo area that will allow you to route wires to the underside of the vehicle. The grommets are typically found behind the rear trim panels, in the spare tire well, or under the threshold. When we installed the Curt Wiring Harness Kit, # 56146KIT, on a 2011 Volvo XC70, we found a grommet just under the spare tire (see photo). The 2011 XC70 is the same generation as your 2009 XC70, so you should have this grommet as well. Sometimes the gro

Powered Wiring Harness Recommendation for a 1985 Peugeot 505 Sedan
The correct powered wiring harness for your 1985 Peugeot 505 sedan is the Curt Powered Wiring Harness, # 56146KIT. This is basically the same wiring harness as the # C56175 that you referenced except it has the additional power lead for the vehicle battery. The # 56146KIT is the harness that I would recommend for your vehicle. Using a powered converter box will keep the additional power draw off of your vehicles tail light circuits and will provide more power for trailer lights. This kit als

Will the Tow Ready Wiring Harness # 119179 Fit on a 2006 Volvo XC70
The Tow Ready Modulite Wiring Harness, # 119179, is the correct wiring harness for your 2006 Volvo XC70 wagon. This harness was designed not to interfere with any bulb warnings or sensors on your vehicle. This harness uses power from the vehicle battery to power the lights on a trailer, so it will not draw any power from your vehicles tail light circuits. The wiring harness simply uses the signal from your tail light circuits to tell the converter box when to send power to the trailer connector.

Will the Curt Wiring Harness # C56175 Work on a 1999 Saturn SL2 with LED Tail Lights
If your 1999 Saturn SL2 came with factory LED tail lights, then we do have a wiring harness that will work, however, the Curt Wiring Harness, # C56175, is not the correct wiring harness for you. Instead, you will need a wiring harness with a powered converter box like the Curt Powered Wiring Harness, # 56146KIT. Vehicles that come with LED tail lights do not have enough power on the tail light circuits to power lights on a trailer. A wiring harness with a powered converter box is required be

Trailer Wiring Harness for 1999 Lexus RX300
PWM stands for Pulse Width Modulation, which is a particular wiring system that some vehicles use. Instead of having a single wire for each different circuit, PWM will use the same wire for two or more circuits by using varying pulses for different functions. PWM is a fairly recent technology, your RX300 uses a more traditional wiring system.

Trailer Wiring Recommendation for a 2013 Chevy Express Van
What I would recommend you get is a Curt Custom Fit Vehicle Wiring # 55540. This wiring kit plugs inline with the tail lights of your vehicle and will activate the trailer lights of your small trailer. Curt has determined that you do not necessarily need a powered unit like the Hopkins Converters # 46255 or # 46365 and since your trailer only has two lights on it I think the # 55540 would work well for you. The main difference between the # 46255 and the # 46365 is that the # 46365 can han

Trailer Wiring Harness Recommendation for a 2012 Kia Sorento
The main difference between the Curt Modulite Wiring Harness, # 56146KIT, and the Curt T-Connector Wiring Harness, # C56163, is that the T-Connector harness, # C56163, simply plugs into the factory tail light connectors at the back of the tail light assemblies. The Modulite Harness, # 56146KIT, will need to be hardwired into your vehicles tail light circuits. I would recommend using the T-Connector Harness # C56163 because you will not need to cut or splice into your vehicles tail light wire

4-Way Trailer Connector on 2002 Ford Ranger Does Not Fit Trailer Side 4-Way Connector
If the two connectors look exactly the same then they are not going to fit. They should be mirror opposites of each other.

How to Hard Wire a 2013 Ford Fusion for Towing a Trailer

What are the Functions of a 5-Way Flat Trailer Connector with 8 Wires
On a 5-Way trailer connector, usually found on boat trailers, the pin on the end furthest from the ground pin is used on an electric reverse lockout on the trailer coupler.

Troubleshooting Trailer Taillight Malfunction Connected to a 2006 Volkswagen GTI
It sounds like you might have a ground problem on the trailer side of the wiring. Nearly every time there is bizarre behavior on the tail lights of a trailer its because of a faulty ground.
