• Does Vehicle Have Fuse for Running Lights
  I am not sure what truck you have but it is very common for vehicles like trucks that have factory trailer wiring to have fuses for the various trailer taillight or vehicle taillight functions. So it could be a blown fuse or it could be as simple of a fix as cleaning off corrosion that has developed on the pins of the trailer wiring. If you grab the owners manual there will be a section that covers all of the fuse box positions.

• Does T-One Vehicle Wiring Harness 118384 have Combined Brake Light and Turn Signal Functions
  Tow package wiring on a vehicle is already converted to combine the brake and turn signal lights onto the same circuit which is what trailers use. Wiring harness # 118384 Tees in line with the factory 7-Way wiring and provides a 4-Way flat connector in addition to the factory 7-Way so when using it the brake and turn signal lights will also be on the same circuits.

• Troubleshooting Running Lights and Left Brake Blinker Not Working on Trailer
  First thing you should do at this point is test the 7-way of the wiring harness with a circuit tester part # PTW2993 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. Since it's one side of the trailer not functioning...

• 2013 Nissan Xterra 7-Way and Trailer Running Light Solution Fix
  Since the solution for no running lights on your 2013 Nissan Xterra is a missing relay and you also want a 7-way kit your best solution would be the part # C56226. You already have some of the relays but you'll be able to use one of the extra blue relays to fix the running light circuit and you get everything needed to install the 7-way. This relay is traditionally found under the dash to the left of the steering column. There is a socket there to plug in the relay that will activate...

• All Lights Work But Trailer Showing Not Connected on 2013 Ram 3500 with Factory Brake Controller
  You're likely correct that this issue is with the truck, and I know that with the first generation of the factory integrated brake controllers on the Ram trucks there were a lot of issues like this that people have seen. You also mentioned that you changed the 7 way connector on your truck, so corrosion on the connection isn't going to come in play since it's new. I would start by checking the ground wire connections on the trailer and your vehicle's 7 way connection. You'll want to make...

• Class V Trailer Hitch for a 2014 Ram 1500
  Yes, you can install a Class V trailer hitch on your 2014 Ram 1500. Curt hitch # C15572 is rated a Class V, but it has a 2 inch receiver. The tongue weight capacity is 1,500 pounds, and the gross trailer weight capacity is 15,000 pounds. You will need to stay within the capacities of the truck though since it is rated lower than the hitch. I have included links to the instructions and a video showing a typical installation for you. I also recommend etrailer ball mount kit # EBMK2416. it...

• Installing Trailer Wiring Harness on 2013 Nissan Xterra w/out Tow Package
  If your Xterra was not equipped with the factory tow package the port under the vehicle where the 4-pole trailer connector like part # C55441 plugs in will NOT be fully active. There is a jumper harness and relays that are needed to activate the tow package. The Curt # C56225 that we offer includes the 4-pole that plugs into the connector along the drivers side frame rail alongside the spare tire, as well as the jumper harness and relays. The relays plug into the jumper harness, which...

  First, unplug the # 3050-P connector from the rear of the controller, and use a circuit tester like part # PTW2993 to test the pin fed by the black wire. If you're getting power, make sure the pin is correctly aligned.

• Troubleshooting Service Brake Controller Message on Ram 3500
  Here's what I was able to find for error messages similar to what you listed for a Ram truck: SERVICE TRAILER BRAKE SYSTEM: This message will display when there is a problem with the ITBC system. If this message continues over multiple ignition cycles, there is a problem with the ITBC system. Have the vehicle serviced. First thing I would check though is for corrosion on the trailer wiring connector as that's the most common cause of brake controller issues. Clean the pins with sandpaper...

• Adding Extra Tail Lights to a 2002 Chevy Silverado with Tommy Lift Gate
  If your 2002 Chevy Silverado does not have a 7-Way trailer connector at the back then check up around the spare tire for a wiring harness. The harness will either be just blunt cut wires or there will be a round connector.

• Can The Curt C62VR Wiring Harness Be Used On A 2018 Jeep Grand Cherokee With Factory Tow Package
  Though it is perfectly fine to use the Curt # C62VR even if your 2018 Jeep Grand Cherokee has the factory towing package, I don't necessarily recommend it. Reason being, if your vehicle was set up with that package, it will have wires run that are specific to it. These tie into the vehicle's computers for diagnostics and other technical what have yous, but they are there to make life easier. Something like the Tekonsha # 118384 (whos harnesses I prefer due to them lasting longer) will plug...

• Troubleshooting Trailer Wiring with Lights Not Working Completely
  I think I can help but it still sounds like a ground connection issue. Here is why...whenever some functions work and others do not, it is either a connector issue, a short in the wire, or a weak ground. Since everything works on both the trailer and truck when tested independently, and when you partially plug in the system it seems to work better than fully plugged, it definitely sounds like a ground issue. Since you have already cleaned up your grounds, I recommend moving them. Make...

• Can TIPM of 2011 Ram be Bypassed so that Trailer Running Light Circuit Can be Repaired
  It's probably controlled by the TIPM which requires a dealer visit to reset which is super annoying. To bypass this you could wire in a universal 4-way to your taillight wiring which you could then run to your current 7-way. For that you would need the part # 119178KIT.

• How to Troubleshoot Intermittent Malfunctioning Left Turn/Brake Signal on Trailer
  Because it sounds like you're describing an intermittent issue, you're most likely dealing with a poor ground connection. It's lot likely the main trailer ground on the trailer tongue is the problem since it's only happening on one circuit, but it's worth checking to make sure the ground wire from the trailer connector is securely fastened and isn't corroded. The ground for the left turn/brake lamp is where you'll most likely find the problem. Trailer taillights either ground by their mounting...

  If your service trailer brake system indicator light comes on then there are a few common things to check.

This could be a a loose or corroded ground connection on the trailer or a short in the output wire for the brake assemblies.
