• Installation of the Positive Connection from Wiring Harness To Battery on My 2005 Dodge Magnum
  If you installed the power line from the converter to the battery you should have power to the trailer lights. The terminal under the hood is fused so it would provide an extra layer of protection, but is not necessary as long as the inline fuse is used. If all the other wiring is connected properly to the connection points behind the taillights. You may have a bad ground somewhere or the fuse may be bad if you did not remove it before installing the power wire. If you did not install...

• Why Does Power Wire of the Trailer Wiring Harness for 2005 Dodge Magnum Need to be Run to Battery
  The reason you want to run the power wire all the way up to battery is so that you bypass all of the delicate wiring of your vehicle. The power wire is required on trailer wiring harnesses for some vehicles because the electrical system on those vehicles cannot handle the amperage draw associated with trailer lights. Powering the converter box with a power source that doesn't come from the battery would defeat the purpose. I attached an FAQ article on routing the power wire for you to...

• Troubleshooting Trailer Wiring Harness on 2007 Dodge Magnum with Always-On Left Brake Light
  You did indeed purchase a trailer hitch from etrailer back in January of this year but I did not find a record of a wiring harness purchase. In any case the problem you describe is most likely caused by either a damaged wiring harness or by a bad connector at the vehicle or trailer. I suggest you first check that the ground wire is firmly attached to a clean bare metal surface. A bad ground can cause all sorts of weird issues. If this does not help next disconnect the harness connectors...

• Why Would Going with Larger Fuse in Tariler Wiring Cause it to Burn Up
  The higher fuse you installed is the reason the harness burned up. The rating of the fuse is designed to kill the connection if a short is present that would cause damage. By going with a higher rated fuse you essentially allowed the connection to stay in tact beyond the amperage rating of the wiring so it ended up burning itself. The fact that you were blowing the properly rated fuse indicates that you had a short or were overdrawing the harness which should have been what was addressed...

• Parts Needed to Install Brake Controller in 2005 Dodge Magnum
  You will need to start with a 4-way (if you do not have one). For that you would want the # C55562. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake...

• Recommended Curt Receiver Hitch for 2005 Dodge Magnum RT
  Curt offers two different receiver hitches for your 2005 Magnum, the Class II you mentioned, part # 12240 or a Class III, part # 13465. Although both receivers would work great on your vehicle, I always recommend choosing a Class III with a 2 inch receiver opening over the Class II with the 1-1/4 inch opening whenever the option is available. The more common Class III 2 inch receiver will provide a better selection of hitch mounted accessories like bike racks or cargo carriers. If you...

• Troubleshooting Trailer Wiring that has Blown Up Two Tail Light Converters
  Although taillight converters, just like any other electronic device have a set lifespan, losing two of them in rapid succession tells us that something is going on. The two most likely causes are a short circuit in the trailer wiring and overloading the converter. First, check the wiring on your trailer. Beginning at the trailer connector and working your way back to each lamp, closely examine the wiring. Wire insulation can become brittle over time, look for any cracked or worn wire...

• Trailer Lights Do Not Turn On but Wiring Harness on 2006 Dodge Magnum Shows Power
  Sounds like the wiring on the 2006 Dodge Magnum is working since you have tested it. But, make sure that the main ground for the converter is attached to a bare metal surface. Moving the ground might help as well. Sometimes, when there is very little load on a system with a bad ground, like using a tester, the problem will not show up until there is more power draw. I also recommend trying out the trailer on another vehicle if possible. After checking that, that leaves the trailer. Most...

• Troubleshooting T-Connector Vehicle Wiring Harness # C55562 on 2007 Dodge Magnum
