Video Transcript for LubriMatic Wiring 11755 Review

Today we're going to review part number 11755. This is the Lubrimatic Dielectric Grease for electrical connectors. This is a 2 ounce tube. This will help prevent any electrical failures caused by corrosion and moisture. It is a water resistant formula that will shed the moisture and it will not wash away. It is used to protect bulbs, sockets, T connector plugs, and trailer connectors. It comes in this 2 ounce bottle.

It does have a dropping point of 550 degrees Fahrenheit. Basically using this dielectric grease will increase the liability and the life of the connection by preventing corrosion and sealing that connection. I got an example here of a 3-prong plug that would go into the back of a light on a trailer. Basically all you have to do is take some of the grease, put it right on there. That would seal it from any type of moisture or corrosion. That should do it for the review on part number 11755, the Lubrimatic Dielectric Grease for electrical connectors in the 2 ounce tube. .

The t-one harness for my Mazda pu truck was just what I needed to haul a 4 point trailer.The transistion wire harness from a 4 point to a 7 point made it a lot easier to haul a trailer with a 7 point hookup.The installation was very easy for both.I have no doubt this way will solve easy hookup from 4 or 7 point hookup.I am well covered for either. 362771

Dielectric grease is the best lubricant for your electrical contacts on fuses, plugs, etc. Once the contact has been cleaned and dielectric grease applied the contact's will not corrode nor does it inhibit or degrade the flow of electricity thru the contacts. This grease is also very water resistant. This product is a full 2oz which is unusual as most auto supply shops etc. only carry the smaller, much smaller sizes.......and I alway's seem to run out. Etrailer was very quick with delivery of the product......as alway's. 28508

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

Being a new boat owner I was quickly overwhelmed by what I didn't know. Re-wiring, re-lighting my trailer was my first project. etrailer has a wide range of products, but most important to me, was their added product information and instructional information which helped me make the right selections to get this done. Add to that is their very competitive prices. etrailer will be my go to source for my future trailer needs. 313877

I use this to maintain excellent electrical connections between my trailer's electrical cable and my truck. It also maintains a solid connection when I hook up my camping trailer to the pedestal at the campground. I carry a tube of this in my tool box and keep a spare tube in my trailer so that I can maintain "peace of mind" while camping and not have to worry about whether I have a good connection or not. I highly recommend this product! 896943

The shipping box was assembled and built like a tank! It fully protected the heavy hitch and accessories. It was shipped quickly and received from UPS. Unfortunately for me, I don't have the means to install the hitch and wiring, so I'm paying the local Ford dealership to install them. I did have an issue/question on the wiring harness. My vehicle is a 2019 Ford Transit Connect. It appears that the wiring harness box is labeled for 2014-2018 Ford Transit Connects. Being a weekend, I couldn't get any responses from Etrailer to my email request regarding this issue. I was under a time crunch, so I ordered a new wiring harness directly from the Ford dealer at a higher price. I'll be returning the other harness to etrailer. 880155

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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.

  • 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...

  • Intermittent Trailer Disconnected Message on a 2012 Ram 1500
    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...

  • 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...

  • Troubleshooting Trailer Wiring on 2004 Ford Explorer Sport Trac
    The first thing I would check on the Explorer are the fuses (and relays) associated with its trailer wiring. I reviewed an online owner's manual but no information about the fuse box (power distribution box) is included so I suggest that you check the lid on the fuse box. Usually these will have a legend that tells you which fuses are related to towing functions. Check to make sure nothing has caused one of these to blow. A short in the trailer wiring could cause a fuse to blow. If all...

  • Troubleshooting Weak Ground on 2004 Silverado and Trailer Wiring
    No worries. What you describe sounds like the classic case of a bad ground. Because vehicle headlights use a fair bit of power and remain on continuously (rather than blink) they often are the lighting function that causes a weak ground connection to reveal itself. Find the main ground wire from the truck's trailer connector and find where it attaches to the truck metalwork. You may need only sand off this grounding point so that you can re-attach the ground wire to clean bare metal....

  • 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.

  • Troubleshooting Trailer Light Fuse that Keeps Blowing in a 2016 Toyota Sienna
    A 30 amp fuse will likely fix the problem of the fuse blowing but fuses are meant to safeguard against wiring overheating it would be dangerous to do so and could result in a fire. It sounds like you simply have a short somewhere. Start off by checking the connector on your 2016 Toyota Sienna and your trailer. Clean out any debris or corrosion and apply some dielectric grease like part # 11755 to help keep them clean and protected. If your connectors look good then you need to check...

  • 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.

  • 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.

  • Troubleshooting Brake Controller Malfunction When Trailer Plug Gets Wet
    In order to protect your circuit breaker and your controller, you do need to keep moisture out of the electrical connections causing shorts. My recommendation is to use dielectric grease # 11755 to keep moisture and debris out of your connections. Use this at any connection point to give you a more secured connection. If you don't already have a cover for your trailer connection on your trailer, I recommend replacing your connector with one that has a spring loaded cover to keep a tight...

  • 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.

    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...

  • 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....

    It sounds like you have a short somewhere. This is the result of a bad ground or some damaged wiring. Check your grounds and make sure they are secure and connected to clean, bare-metal surfaces and that your wiring isn't damaged or pinched. You can also check the connector on your tow vehicle and trailer to see if there is any corrosion. If you do find corrosion in either connector clean it out and apply some dielectric grease # 11755. Let me know if this doesn't fix your problem...

    The problem is that you have a short somewhere in your wiring setup. Since the fuse has blown while using 2 different trailers this leads me to believe that the short is on your 2006 Jeep Grand Cherokee. You will want to start off by checking the 7-Way connector on your Jeep. Look for any debris or corrosion and clean it out. You will also want to inspect the wiring that runs to your 7-Way. Look for any places where the wiring is damaged, bent, exposed, or corroded and replace as necessary....

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...
