My F150 had an OEM 4 pin trailer plug and hitch. The 118242 - 7 pin connector with wiring harness is the ticket. The hardest part of the install was dropping the spare tire. The plugs connect directly to the factory plugs and the harness length is the correct length. The 3035-P brake controller connector harness was just as easy. Plugs right in to the OEM plug next to the ECM connector and the other end into the brake controller. The PK12711U-26 - 7 pin bracket and hardware kit fastens directly the OEM bracket that is on the hitch. My truck had an OEM 4 pin trailer towing set up with the hitch. The OEM hitch had the bracket welded on it to attach the 7 pin mounting bracket to it. These kits make this install very easy and professional looking. If I have one complaint, the hardware kit to attach the 7 pin connector bracket is set up to fasten the bracket directly to the bumper with 2 - self tapping screws provided in the kit. The kit also includes 4 #12 machine screws with toothed washer nuts to attached the 7 pin connector to the bracket. This is fine if your truck hitch doesn't have an attaching bracket welded to it. The kit should included in it 6 #12 machine screws and nuts along with the 2 self tapping screws. Since my OEM hitch actually had a bracket welded to it to attach the 7 pin bracket to it, I had to use two other #12 screws and nuts to attach the 7 pin bracket to the OEM bracket on the hitch. Not a big deal, just a thought. It took me about 2 hours, start to finish to install the 7 pin connector, trailer controller, and add the two relays in the OEM relay/fuse box under the hood. I highly recommend these kits. 322337

  • Trailer Lights Acting Funny Is It a Ground Issue
    Everything you are describing here - the turn signals going slower, some lights activating when you activate certain light functions - points to a poor ground with your truck. The fact you have used the trailer with other trucks and have not had the same problem points to the ground being an issue. You will want to check your harness ground and need to make sure your grounds are attached to bare metal surfaces and free of any paint, dirt or corrosion. I have added links to help articles...

  • Troubleshooting Trailer Running Lights Not Working With 2019 Ram 3500
    Typically when parking or clearance lights stop functioning, the issue is a poor ground connection so I'm confident that's the problem here. What you'll need to do is make sure your grounds are attached to bare metal surfaces and free of any paint, dirt or corrosion. The other potential problem are your connectors. You will want to check the trailer connector on your 2019 Ram 3500 and trailer for corrosion, which can be green or white in color. A build-up of corrosion can interfere with...

  • Boat Trailer Brake Lights Do Not Work when Running Lights are On
    If your brake lights do not work only when the running lights are on, my best guess is that you have a poor ground causing the issue. So you'll want to make sure your grounds are attached to bare metal surfaces and free of any paint, dirt or corrosion. This issue could have happened as you were putting new lights on, with the other possibility being that if your brake lights were LED and you switched to incandescent, maybe you have an overload though that seems less likely. I have...

  • Best Trailer Wiring Harness for 2003 Ford Escape
    The trailer wiring harness I recommend for your 2003 Ford Escape is the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118343 because of its reliability and ease of installation. This harness does not require running a hot lead to your Escape's battery, unlike other wiring harnesses for vehicle, which is going to make it much simpler to install. I have added a link to a video install for you on a 2003 Ford Escape of the T-One Vehicle Wiring Harness # 118343. If...

  • Trailer Brakes Not Working On A 2016 Chevrolet Silverado 3500
    The first thing you will want to do is check the inside of both the vehicle's and trailer's connectors for debris or corrosion. If corrosion is present, you will then want to spray some electrical parts cleaner on the inside of the connectors to clear the debris. The next thing you will want to do is test the 5 o'clock pin at the back of the vehicle's trailer connector to make sure it is receiving power when the manual override on the brake controller is activated, you will need to have...

  • Electric Brake Compatibility on a Boat Trailer
    Electric brakes on a boat trailer are able to be used without much issue at all. There obviously is an issue with water and electricity, so it is recommended to disconnect the trailer connection when your trailer is being submerged for launch. A few seconds after pulling out of the water, you can connect your wiring without any issues and have the functioning braking system that is easier to maintain. Many boat trailers are moving to electric systems. I do recommend using dielectric...

  • Trailer Disconnected Error Message
    The most common cause for a trailer brake controller to display the 'no trailer connected' error message is a damaged or corroded connector on the trailer. Corrosion can occur inside a connector too so you'll want to re-inspect both the external contacts and the back/inside of the connectors if possible for signs of any corrosion. Even slight greenish or whitish discoloration can indicate a corrosion issue, and certainly it can also happen that there can be severe corrosive build-up...

  • LED Trailer Light Voltage Loss
    It sounds like you did it the right way this time! To track down this voltage loss, I would recommend a few things. First, make sure that your trailer and vehicle side are properly grounded to clean, bare metal. Secondly, double check all of your connections, from the trailer connector on back, checking for pinched wires. Using some dielectric grease, like part # 11755 on all of your connections, including the trailer connector, to protect against water and corrosion. LED lights actually...

  • Trailer Warning Lights Flash in Vehicles Message Center
    The trailer warning lights flashing in your message center sounds like either a ground issue on the trailer or a corrosion problem between the trailer connectors. I would first start off by disconnecting the trailer connectors and using a bit of electrical spray to clean the pins. Once done, I would also use a bit of dielectric grease like part # 11755 between the two connectors before mating them back together to prevent future problems. Before you move onto the trailer wiring, I also...

  • Can Butt Connectors Be Used in Place of Quick-Splice Connectors for Installing LED Trailer Lights
    Yes, since all the running/clearance lights on your trailer will be fed by the same circuit you can use butt connectors rather than quick-splice connectors to enable a longer-lasting and more water-resistant connection. Wiring the lights as you described is fine. I also suggest using dielectric grease # 11755 in/on all connectors to prevent entry of water and contaminants that could eventually cause connectivity issues.

  • Trailer Keeps Blowing Fuses on Tow Vehicle
    You are correct, if you know that your trailer is causing an issue with your fuses blowing then you will want to check the connector, wiring, and the grounds. Make sure that the connector is free of any debris or corrosion. Clean it anything out that might be there and apply Dielectric Grease # 11755 in the connector to help keep it clean and in proper working order. To check the wiring you will want to look for any places where the wire has been bent, damaged, corroded, or has exposed...

  • Intermittent Trailer Braking Signal From Brake Controller
    An intermittent trailer brake signal is generally caused by one of two things. The first of which is the easiest to check and will be the ground circuit. You will want to ensure that the ground is securely attached to a bare metal surface on the frame. The other possible cause of this problem could be a corroded trailer connector. You will need to clean inside both of the trailer connectors looking for dirt and debris. Use the Dielectric Grease for Electrical Connectors part # 11755 before...

  • Troubleshooting Pulsing Brakes when Blinkers are On
    The right turn blinker circuit of your trailer is shorting out to the brake output circuit (signal that carries the brake controller voltage) and that is why you are experiencing the pulsating. Starting at the trailer connector on the trailer you will need to trace the wiring back from there to the brake assemblies looking for any cut or exposed wire and fix as necessary. I attached a help article on brake controllers for you to check out as well.

  • How to Correct Weak Ground Connection on Vehicle and Trailer
    A hitch ball does not make a good ground connection for trailer lighting functions. The fact that the lights work for a bit after you hit a bump with the hitched trailer tells us that somewhere in your trailer and vehicle wiring there is an intermittent ground connection. This kind of problem usually has a fairly simple fix. I suggest you locate the tow vehicle's wiring harness ground wire. This white wire needs to be firmly attached to a clean bare metal surface on the vehicle. On the...

  • How to Prevent Corrosion on a 4-Way Trailer Connector
    For a cover designed to fit over standard 4-way connectors we have the # C58200. Another very helpful idea will be to put dielectic grease on the pins of your 4-way. This will actually be your best way to fight the corrosion. For that you would want the part # 11755. Basically you will need to apply a liberal amount of it all over the pins of the connectors before you put the cover on the 4-way and you will not have to worry about corrosion.

  • Troubleshooting Blown Fuses on Running Light Circuit of 7-Way Socket
    The easiest way to troubleshoot your trailer lighting functions is when it is not connected to the tow vehicle. Apply 12V power from the truck's battery or a well-charged spare if you have in the garage directly to the contacts on the trailer plug. Direct power input to the trailer plug lets you test the trailer running/clearance/license plate light function in isolation, without any possible interaction with the vehicle. A set of jumper cables and two short lengths of 10- or 12-gauge wire...

  • New Trailer Brakes Pulse In Rhythm with the Left Hand Turn Signal
    It sounds like the brake controller is picking up some of the current from the blinkers. Installing a Pulse Preveneter, part # 5501, should remedy the issue. A pulse preventer essentially filters out the fluctuations created by the blinkers so that only the constant signal of having the brake pedal applied will activate the controller. I have added a link to the part below.

  • Troubleshooting Right Trailer Brake Light & Trailer Brake Controller Not Working
    Thanks for providing the details on your trailer wiring issue. Since you have three trailers that all show the same issue when connected to your 2004 Chevrolet Silverado odds are good that the problem is in the truck wiring. The first thing to check is the ground connection on the vehicle wiring harness. This wire's ring terminal must make a clean metal-to-metal connection in order to allow for all functions to operate properly. Corrosion can build up and cause issues. Try removing...

  • Possible Causes for Dim Trailer Lights
    Most often the root cause for issues with trailer lighting is a weak ground. Strange as it may sound, a loose or rusty/corroded ground can cause a vehicle's trailer wiring harness to badly misbehave and shut down some functions. It may also just limit the amount of current that can flow to the lights and this will result in dim illumination. The easiest way to check the trailer ground is to disconnect it from the vehicle and apply 12V power (from a well-charged 12V battery) directly...

  • How to Secure 7-Way Wiring Harness to 7-Way Socket With Broken Locking Tab
    If your 7-way harness' locking tab broke you could replace the wiring harness if you wanted to or you can simply snug it up with a zip tie. I suggest that you disconnect the plug from the 7-way, clean the contacts as needed, apply a protective coating of dielectric grease # 11755 to block moisture and contaminants from entering and secure the harness to the 7-way with a zip tie, something like # 853-3194-02. Wiring kits for your truck are linked, for reference.

  • When is it Recommended To Use Dielectric Grease When Wiring
    We want to thank you for your recent purchase! You wouldn't need to use dielectric grease with a butt connector such as part # DW05714 (view video at the 1:16 mark) as electrical tape will work great. Heat shrinkable tubing such as part # DW05451 will help protect against the elements. It works with 14-18 gauge wire. Most trailer light wiring is 16-gauge. Once you have your wire inside the tubing you can use a heat gun, blow dryer and/or lighter utilize the heat shrinkable tubing....

  • Troubleshooting P.L. Error on Prodigy Brake Controller 90185 Installed on a 2005 Yukon XL
    I would actually check the connection between brake controller and your factory port. Often you would see the P.L. if the connector wiggled slightly loose from where it is plugged into your junction box, especially if it is only happening once in awhile. Try unplugging the brake controller from the junction box port and let it sit for three minutes. When you plug it back in, make sure the connectors are firmly clicking together. You will need to reset the controller brake power and...

  • Troubleshooting Running Lights on Trailer Towed by 2014 Nissan Armada
    Most of the time, when trailer running lights do not work but all other lights do work properly the cause is a weak ground connection. Since running lights stay on continuously, unlike stop/turn lights, they draw more current and a weak ground may allow the other functions to operate correctly but not pass enough continuous current for the running lights. The fix is simple in this case. Find your trailer's main ground wire (and do the same thing on the wiring harness on the Armada) and...

  • Installing Dielectric Grease on 7-Way Plugs to Prevent Corrosion and Keep Electrical Connection
    Dielectric grease is basically just applied in a thin coating to the connector plug. You can use # 11755 or # LT37534 if you prefer a smaller amount. I've attached a video to assist. Just like the connection on the back, you can add this to the trailer pins on the front of the connector as well to keep moisture and debris out to prevent corrosion. I've attached an article to help as well.

  • Trailer Marker Lights Are Too Bright Suddenly
    I think you hit it right on the head when you mentioned the grounds. That is very often the cause of all sorts of odd lighting issues - and lights suddenly getting brighter is definitely one of them - so I recommend ensuring those grounds are good as I suspect that's the issue. I have also added a link to a help article on wiring troubleshooting which may be helpful.

  • Tail Light Fuse on Truck Keeps Blowing When Trailer Wiring is Connected and Then Trailer is Coupled
    There are a few things that you will want to check since your tail light fuse keeps blowing when you couple your trailer. Start off by checking the connector on your truck and your trailer. Make sure that it is clean and free of debris and corrosion as that can cause power from other circuits to bleed over to the running lights. Using dielectric grease like part # 11755 on your connectors can help prevent water damage and corrosion. If the connectors look good then you will want...

  • Troubleshooting The N.C Code Flashing On Brake Controller
    The NC means not connected, so your brake controller isn't seeing your trailer because there isn't a power draw on the brake controller output wire. Often this is because of corrosion at the connections or a bent pin. Check and clean your connections and add a little dielectric grease # 11755 to help that connection. Sometimes there needs to just be a little more of a amperage draw on that brake wire for the controller to see connection. You can use a circuit tester like # PTW2993...

    The intermittent trailer disconnected message that is appearing on your 2012 Ram 1500 is generally caused by corrosion in the trailer connectors but since you have already checked that we can eliminate that possible cause. I will say that although it may not appear that corrosion is present, you will still want to spray each end with some electrical cleaner and then use some dielectric grease like part # 11755 before mating them back together. Once you have cleaned and greased the inside...
