Perfect 435706

- SWC50122

A great way to attain water proofing your wiring work. Didnt know this was on the market but I'm glad I did! 418236

- SWC50122

I am a heat shrink all the way type person. I use this on the connection areas were the heat shrink does not close completely (two wires into one heat shrink tube) to close off wires to the elements. This Liquid Tape stays flexible for quite a while & have had no issues with water corrosion since I started using it. 230719

- SWC50122

The Star Brite Liquid Electric Tape is exactly what I needed and the product shipped quickly. I would definitely do business with etrailer.com again. 144879

- SWC50122

Quality product, on time, great price. Any other questions? 87011

- SWC50122

As an electronic tech I have used this and simular products for many years. It is invaluable for wiring that will be exposed to the elements such as wire connectors located underneath a trailer or vehicle. 73802

- SWC50122

Product worked good. Only problem was it did not work over electrical tape, seemed to make the tape come loose. I took the tape off of the connection and just used the liquid electrical tape and it seemed to work well. 34661

  • How to Rewire Vintage Trailer with 7-Way Connector and Parts Needed
    Most of us aren't electricians, but that doesn't mean wiring a trailer is beyond us. It will take a little bit of time, but I wouldn't consider it a difficult DIY project by any means. So, to wire your 1977 Serro Scotty vintage camper, I recommend using the following parts: - Mighty Cord 7-Way RV-Style Trailer Connector # A10-7W6 (6 ft long) - this is a high quality molded trailer connector with corrosion resistant terminals. - etrailer Trailer Wiring Junction Box - 7 Terminal # e99009 ...

  • Can Bargman Triple Trailer Tail Light be Exposed to Water
    Good questions, and the answer is the Long LED Triple Trailer Tail Light # 47-84-104 are a recessed mount and the back should not be exposed. I checked with Bargman, the manufacturer, who has not deemed them "weatherproof" so they are not lights you are going to want to expose to the elements in any way, and there really isn't a reliable way to make them water resistant with the rear of the light exposed. You can use Liquid Electrical Tape # SWC50122 as a sealant on the electrical connections,...

  • Is there an Adapter that will Convert a 4-way Round Trailer Connector to a 4-way Flat Vehicle End
    I have checked the adapters that we currently carry, and we do not have an adapter that will fit the configuration that you specified. You could create your own adapter, and it would be composed of the Pollack # PK11410 and the Hopkins Endurance 4-way Flat Trailer connector # HM48110. You would just wire the Hopkins 4-way flat to the Pollack 4-way round connection point. This will create an adapter that will connect the 4-way round on your 1972 trailer with a 4-way flat vehicle connection...

  • Options for Repairing or Replacing Damaged Electric Drum Brake Magnet Leads
    You may be able to repair/replace the damaged magnet wire from your trailer's electric brake if you can get access to it. You may have to remove the wheel and hub to get access to the magnet wires to allow you to splice in a length of new 10-gauge wire like # 10-1-1 using a butt connector like # 05732-2. Another option is using Liquid Electrical Tape # SWC50122 but new wire is the better long-term fix. Another option is replacing the entire magnet, which will include new wire leads....

  • How to Wire Electric Trailer Brakes on a Boat Trailer
    To run the brake lines on the trailer, you don't need the dual cable. I'd recommend using 10 gauge wire, part # 10-1-1 which is sold by the foot. Run the wire from the trailer connector back to the axle, cut the wire and strip the end. Use a butt connector like part # 05732-2. Run a lead to power each brake assembly out of the other side of the butt connector. Use some liquid electrical tape, part # SWC50122 to seal the connection. At each brake assembly, the brake magnet has two leads....

  • Recommended Wire Gauge and Related Parts to Install 12V Battery Charge Line on 7-Way
    We recommend at minimum a 14-gauge wire for providing 12V charging power to a towed vehicle's battery, such as that included in the Roadmaster Battery Charge Line Kit for Towed Vehicles, item # RM-156-25. Naturally, a heavier-gauge wire would do better since it can deliver more current. If you prefer you can use 10-gauge wire # 10-1-1, a 40-amp auto-reset breaker like # PK54540, ring terminals # 44-5310A and wire loom # 7509-10 to make your own kit. You can avoid tripping the breaker...

  • Recommendation for Submersible LED Backup Lights on a Boat Trailer
    I can help you add reverse lights to your trailer. Yes, It is important to pay attention to DOT compliance when adding lights on your boat trailer. Compliance will be met if you use the Optronics # BUL10CB light as your backup light. The # BUL72CB is purposed for a utility light and will not meet the criteria for reverse lights on the roadway. In order to add reverse lights to your trailer would would need to have a 7-Way on the trailer and a 7-Way on the vehicle. On the vehicle...

  • Waterproofing Trailer Taillight Assembly Connections on a Boat Trailer
    What you can do is apply something like Liquid Electrical Tape, # SWC50122, which will insulate, seal, and waterproof electrical connections. I would still recommend wrapping any connections with actual electrical tape as well for extra protection. Another option is to use heat shrink tubing which is usually available just about anywhere tools and/or automotive parts are sold. With this you would first place the tubing around one of the wires before making the connection. Then use a...

  • Replacement Trailer Lights for Shorelandr Boat Trailer
    The Optronics Tall Rectangle Submersible LED Trailer Tail Light, part # STL56RB, should work on your Shoreland'r trailer. The same light for the left side of the trailer is the Optronics Submersible LED Trailer Tail Light, part # STL57RB. We have gotten back many reviews of these lights working just fine on Shoreland'r trailers. I will give you the dimensions of the lights so you can make sure they will fit your trailer. The light is 6-1/16 inches long x 3-5/8 inches wide x 2-1/4 inches...

  • Recommendations for Splicing Running Light Wires on a Tear Drop Camping Trailer
    Instead of using a quick splice connector, I recommend splicing into the wiring using a butt connector and then using some shrink tubing or liquid electrical tape, # SWC50122, to seal the connections from the elements. We have different size butt connectors like # 05732-2 for 12 to 10 gauge wires and # 05731-5 for 16 to 14 gauge wires. You will want to be careful when adding lights to a trailer. If you add too many lights, it could be too much power draw on the tow vehicle electrical...

  • Availability of a Submersible White Backup Light for Boat Trailer
    The brightest, submersible, 12 volt LED light that can be used as a backup light is # BUL10CB. It is flush mount (use grommet # a70gb). LED are brighter than incandescent lights. You will also need a wiring harness, # A49PB, to connect to the light. While the light is submersible, the wiring connections will need some attention to keep out water. I recommend using use shrink tubing. You can also use liquid electrical tape, # SWC50122, to cover wiring splices to keep out water. Dielectric...

  • Trailer Wiring Repair Kits and Parts
    If you need to do a temporary wiring repair on your trailer the wire color used does not matter but the wire gauge can matter. The brown and yellow wires on your trailer carry stop/turn and tail light signals and probably were either 16- or 18-gauge. Using solid wire instead of stranded wire is okay, but solid core wire can be harder to work with since it is less flexible and harder to twist together for splicing. Also, solid core wire will typically do less well with vibration since it...

  • Sealed LED Trailer Lights for a 2006 Nitro 591 Boat Trailer
    The more diodes the LED lamp has, the brighter it would be so if that is a concern then go with a model that has more diodes. You can take a look at the 48 diode model, # STL70RB, in the review video I have included. These lights use a 3-prong wiring harness like # A45PB. I cannot promise that it will be the same as your existing 3-prong connector. If you have to make splices, I recommend sealing out water using liquid electrical tape, # SWC50122. These lights can be mounted using grommet...

  • Availability of a 5 way Round Trailer Wiring Diagram
    There is no standard diagram for the 5 way round connector, item # PK11501. You will need to use a circuit tester, item # 40376, to test the wires and wire the vehicle and trailer to match. When wiring, your green wire will be right turn/brake, the yellow wire will be left turn/brake, the brown wire will be the taillights, and the white wire will be the ground. From there, you can wire the remaining pole to any function you like such as power for trailer accessories, electric brakes,...

  • Are Clearance Lights Needed on a Snowmobile Trailer
    To equip your snowmobile trailer with a basic lighting setup, you would need amber front side marker lights and red rear side marker lights. A basic trailer would require a minimum of two each, with the front lights as far forward as possible and the rear lights as far back as possible. The # TLK36RK trailer light kit includes the required amber front marker lights , but you could also add matching red clearance lights # A91RB with chrome bases # A91CB. I would also recommend...

  • Wiring a Side Marker Light to the Running Light Wire on a Trailer
    You can run a jumper wire to T-off from the main running light wire to the side marker light using something like a quick splice connector, # 562. Or you can use a butt connector, # 05732-2. In one end, place the wire from the trailer connector and in the other end insert the wire from the side marker light and the wire to the tail light. You would need to cut the brown wire at some point to wire it in this manner. And yet another option is to run the side marker wire all the way...

  • Wiring a Replacement Submersible Trailer Tail Light
    The Optronics Submersible Trailer Tail Light, part # ST16RB, that you purchased will have 3 wires coming out of the back. There will be a white wire for ground, a brown wire for tail light function and a green wire for the right turn and brake function. There is not a molded plug available for this light and you will first want to determine the function of the two wires coming from the plug from the old light. There are two options, the two wires may be a ground wire and a right turn...

  • Does the Trailer Wiring Need to be Waterproof on a Boat Trailer to Avoid a Short or Damage
    If you are going to back your trailer in the water while it is still connected to the tow vehicle, you will need it to be waterproof. Whether or not it is water proof depends on the trailer, the construction, how it is wired, and if the taillight housings are waterproof. You can use shrink tubing, a good amount of electrical tape, or Liquid Electrical Tape, # SWC50122, to help keep out moisture where wires are connected or exposed. To avoid a short or other damage, you should always...

  • Electric Trailer Brakes Lock Up In the Rain
    It sounds like the rain water caused a short and drew power to the electric trailer brakes causing them to lock up. the brake controller, since it is inside the vehicle and not exposed to the elements, would not have been affected by the weather so there isn't an adjustment you would have to make to account for rain. The first and easiest things to check are the vehicle and trailer side connectors. Make sure they are clean and free of corrosion inside where the wires attach and on the...

  • Making Electrical Connections for Tail Light Wiring on a Boat Trailer
    You can use Butt Connectors, like # 05730-5, that you have referenced. To keep out water, you can use shrink tubing around the connections. Or another possible option is to use some Liquid Electrical Tape, # SWC50122, on the connections, and follow that up with actual electrical tape for added protection from moisture and corrosion. The liquid electrical tape will create a waterproof seal which would be ideal for a boat trailer.

  • Tekonsha Primus Brake Controller Blows Power Wire Fuse when Brake Pedal is Used
    It sounds like there is a short that is overdrawing power and blowing the fuse or the draw of the trailer brake magnets is greater than the fuse capacity. The Primus brake controller # TK90160 can work with up to 6 brake assemblies but any more than 2 assemblies I recommend a 30 amp fuse or, better yet, a circuit breaker, # PK54530. Also make sure that the brake controller white ground wire is attached to the negative battery terminal. No other ground location is sufficient. If you...

  • Boat Trailer Tail Lights Stopped Working After Backing Trailer in Water
    There is a subtle difference between submersible lights like # ST7RB and completely sealed lights. Submersible lights will let in water but will allow it to drain out. Sealed lights will keep water out and as such are also submersible. Part of the problem is that you really need to disconnect the trailer wiring prior to submerging the trailer in the water since the light is not sealed and the connection splices are not water tight. The brake light/turn signal functions not working...

  • What Size Heat Shrink Tubing Should be Used with LED Trailer Tail Light STL37RB
    You would need the heat shrink tubing for 18 to 14 gauge wire # DW05452 for trailer tail light # STL37RB. On a boat trailer I would not use crimp style connectors like butt connectors because the chance that a wire could pull out due to broken strands is enough of a deterrent for me personally. I would make the splices needed, then use some liquid electrical tape, # SWC50122, and follow that up with the heat shrink tubing. That would ensure a tight, waterproof connection.

  • Where to Ground Docking Lights On a Jon Boat
    On a boat you would want to ground docking lights # DL-16CC to the negative battery terminal. You will want the connections to be water tight as best as you can. Shrink tubing, electrical tape, and even liquid electrical tape # SWC50122 will help protect electrical connections from water. You can also use dielectric grease, # 11755, between electrical connections. This special grease is hydrophobic so it will repel moisture.

  • What is the Difference Between Submersible and Waterproof Trailer Tail Lights
    A submersible tail light can let water in, there is usually a hole at a low point so the water can drain out. A waterproof light should be sealed to keep out water. For either type, you would also want to seal out water where the tail light wiring splices into the trailer wiring. Shrink tubing works well for this. You can also wrap up connections with electrical tape. Or you could use a combination of liquid electrical tape, # SWC50122, and regular electrical tape. Ideally, if you...

The RBW UHS-88-15, fifth-wheel hitch is not compatible with the Reese Universal Base Rails and Installation Kit, item # RP30035 though.

  • Does 7-Pin 3-Hole Connector Have Rear Cover
    We do have a way to protect this connector, though there is not a rear cover for the Solid 7-Pin 3-Hole Connector - Vehicle Side # PK11-729. Instead, what I recommend doing for protection is simply applying some Liquid Electrical Tape # SWC50122. This will allow a good seal at the rear of the connector to protect it from damage and corrosion.

    Yes, you can splice the wires on the Wesbar trailer tail light # 403075.
