  • Trailer Wiring Diagram for 4-Way, 5-way, 6-Way and 7-Way Trialer Connectors
  • A link to the trailer wiring you are asking about is provided, just scroll down the page to select the connector you have on your vehicle and trailer. The wires on the 5 pole flat are as follows White/ground, Brown/taillights, Yellow/left turn and stop, Green/right turn and stop and Blue/reverse lockout. The brown will run to both sides of the trailer and the yellow and green will only go to the respective side they are needed on. The Blue wire goes to the electric lockout solenoid...

  • What are the Functions of Trailer Light Green, Yellow, and Brown Wires
  • Normally, the green wire on the right side carries right turn signal and brake light functions and the brown wire carries running light functions. On the left side, the yellow wire carries left turn and brake lights and the brown wire again carries the running lights. With only 2 wires, these lights must ground through the mounting studs. Make sure to wire in the new lights by function to the existing trailer wiring and not by color.

  • Trailer Lights Only Work with Camper Plugged In To Shore Power
  • It sounds like the trailer lights are tied into the interior lights and the trailer mounted battery and inverter. What I recommend is to have the trailer exterior lights bypass the rest of the wiring so that the trailer connector is isolated from the other lights. It seems that if everything is connected together through the battery or the inverter, including the trailer connector. Replacing the battery could solve the issue but I would still have the trailer connector separate from...

  • Connecting Harley Davidson 5 wire Harness to a 4 Flat Connector on a Trailer
  • I would recommend you cut off the 5-way on your motorcycle. Wire in a tail light converter kit part # HM48895. This will convert your separate circuit tail light signal of your motorcycle to a combined circuit like what your trailer has. On Harleys the turn signal wire circuit is separate from the brake light circuit so a converter like the # HM48895 is needed to convert the signal into a combined circuit like what your trailer has. You will need a circuit tester like our part # 3808...

  • Trailer Wiring Harness for a 2007 Jeep Grand Cherokee Laredo
  • Wire color used for the tail lights on any given vehicle is not always the same within the same model year of the same vehicle. Based on that you would have to test the wiring with a circuit tester like # 3808 if needed to find the function of the wiring. But it is unnecessary for your vehicle. You need a wiring harness specifically made for a 2007 Jeep Grand Cherokee. You can use # 118425. It takes all of the guess work out and you will not have to test wiring or splice into the vehicle...

  • Parts Needed to Convert a Separate Tail Light Signal of a Honda Goldwing to Combined for Towing
  • It sounds like the adapter you used dropped the brake light circuit when it went from a 5-way to a 4-way. Normally on a 4-way the brake light circuit is on the turn signal circuit. Motorcycles usually have a separate wire/circuit for just the brake lights separate from the turn signals so I believe that is where your problem is from. I believe I have a solution for you, but not with using the adapter you have. I would recommend you cut off the 5-way on your motorcycle. Wire in a tail...

  • Installation and Troubleshooting Wesbar Replacement Lights and Right Turn Signal Not Functioning
  • The Wesbar # 403026 is considered the left hand side, the drivers side, or roadside. The Wesbar # 403076 is for the right hand side, passengers side or curb side. It should not matter which one is installed the wiring to the replacement trailer light is not side dependent. The only difference between the two is that the left hand side # 403026 has a clear section under the light that also functions as a license plate illuminator. If the turn signal on the right hand side is not functioning...

  • Wire Gauge Size For Wesbar Wiring Harness # W002290
  • You are correct that the lower number on wire gauge means that is is a heavier wire. The Wesbar 5-Pole Flat Connector, part # W002290, you referenced has a 5 ft 18 gauge auxiliary blue wire that connects to the backup light circuit to disengage trailer surge brakes when you are backing up. The balance of the wires are 16 gauge. I have attached a couple of links to helpful articles for wiring on trailers you may wish to check out.

  • Connecting a 5-Pin Trailer Wiring Harness for Motorcycle to a Trailer with 4-Way Flat Plug
  • The Hopkins Tail Light Converter Kit with 4-Way Flat Connector # HM48895 will work as long as you do not mind having a 4-way connection on your motorcycle. You will have to remove the 5-pin connector and wire the converter on the motorcycle to reduce its 5 wire system to a 4 wire system. Your trailer should be wired as follows: White wire = ground brown = tail light yellow = left turn and brake green = right turn and brake Attach the white ground wire to a suitable ground on...

  • Testing Vehicle and Trailer Wiring to Install a 5-Way Flat Trailer Connector
  • In order to determine the wiring functions you will need to test them with a circuit tester like # 3808 if needed. On the harness that you referenced, # 20016, white is ground, brown is running lights, yellow is left turn/brake lights, green is right turn/brake lights, and blue goes to the reverse light circuit. Many vehicles have separate turn signals and brake lights so on those vehicles a converter is needed. Converters can be vehicle specific so I would need to know the year, make,...

  • LED Bulb Upgrade for Ranger Trail Trailer Lights
  • Yes, we do have an upgrade for you. First you will need to upgrade your old sealed 102640 capsule to Wesbar Replacement Tail Light Capsule # 403356. This part can be opened and the incandescent bulb replaced. The replacement LED bulb you want is part # P231157W-360-S. On most vehicles LED lights will not cause a situation where the lights will hyper flash, but the only way to know if it will cause that situation on your vehicle is after the LED lights are installed. If that situation...

  • Trailer Left Tail Light Does Not Blink with Turn Signal but Causes Right Turn Signal to Blink
  • The problem you are describing does indeed sound like a ground issue. When a weak ground all sorts of strange things can happen. Make sure there is nothing between the light ground and the metal frame. The tail light should be grounded to a clean and corrosion free bare metal surface. If the trailer has an aluminum frame, tilt bed, or folding tongue, those things can interrupt the ground. Running a jumper wire from the tail light ground to the main trailer connector ground can help. You...

  • Replacement Lenses for Wesbar Wraparound Tail Lights
  • Having a directory that lists the individual part numbers of lamps and lenses used on a given camper would be very helpful, but unfortunately, there isn't such a thing. However, if you can locate a part number on the lamp itself, or provide a photo with dimensions, I would be happy to help find a replacement. Usually, the numbers stamped on the lenses indicate DOT certification, and aren't the part number for a replacement lens. You could send the photo as an attachment to a reply to...

  • Availability of Replacement Capsules for Wesbar Trailer Lights
  • Some Wesbar lights have a the sealed type of capsule, and they are not meant to be opened. Instead, you would need to replace the whole capsule. The good news is that Wesbar offers replacements, depending on the model number, that can be easily opened to change worn parts, in addition to the sealed type. If you have a Wesbar Submersible Low Profile Light # 403026 and/or # 403076, the bulbs can be replaced by removing the clear capsule inside the light. If you have the same light but...

  • Wesbar Wrap Around Trailer Tail Light Replacement Lenses for 2000 Jayco Eagle Trailer
  • Replacement lens set # 105825-26 is the closest match. They will fit Wesbar light 403028. These lenses are 8-1/8 inches across at the widest point, 3-1/4 inches tall, and 2-11/16 inches front to back at the wrap around part of the lens. If these dimensions match then this is the likely replacement for you.

  • Light Assembly Recommendation for a 2003 Shorelandr Utility Trailer BK2200U
  • I couldn't get a decent picture of your trailer or the drylaunch taillight part # 5110377 light assembly. I was able to determine that drylaunch makes a taillight that is basically the exact same thing as the Wesbar Light part # 403075, so if the light assembly you have looks just like this one it will work as a replacement.

  • Old Trailer Wiring 5-Way had 6 Wires But New 5-Way Has 5 Wires
  • The trailer connector that you had is what is called a wishbone harness. It has 2 running light wires so you do not have to run a jumper wire for running lights from one side of the trailer to the other. Wesbar harness # W002290 is an example of a wishbone 5-Way. All you have to do is connect the 2 running light wires from the trailer wiring together and then to the brown wire on the new harness. Or, if you are replacing all the wiring, you would run a jumper wire from one side of the...

  • Are Wesbar Trailer Tail Lights 403026 and 403076 Waterproof
  • A light that is waterproof is sealed. The bulb inside Wesbar light # 403026 is actually # 763560. This is a watertight capsule so water cannot get in. The limiting factor will be the wiring. When connections are made you will need to use heat shrink tubing such as # DW05744-10 to keep water out. Lights that are submersible have openings that water can drain out of. Any light that indicates it is sealed would also not be a problem for marine environments. The Wesbar lights you have...

  • Availability of Bulb and Socket Taillight Kit for Flat Towed Vehicle
  • It sounds like you're speaking of a bulb and socket kit like part # RM-155 from Roadmaster. Installation involves drilling a 1 inch diameter hole into the backside of your taillight assemblies and inserting another bulb. A wiring harness would run under the vehicle to the front, where the harness ends in a 4-pole connector to plug into the trailer connector on the tow vehicle. Keep in mind, not every vehicle will have enough room in the taillight assembly to allow for an additional bulb....

  • Car Hauler trailer Wiring
  • For you to retain the functions of the electric brakes on your car hauler trailer you will need to use a connector that will carry the power for all of the functions from the vehicle. For what you are doing you would be better off using a 7-Way Molded Trailer Wire Connector # H20046 since it has all 7 circuits and the brake output circuit wire has 12 gauge wire. I have attached a video that shows how to replace the 7-pole connector you can check out.

  • Replacement Tail Light for Obsolete Wesbar Trailer Tail Light 403028
  • The Wesbar tail lights that are associated with lens kit # W003372-73 were made obsolete on 3/25/2011. You could replace them with a similar LED version, # 271594 for the right and # 271595 for the left side.

  • 7-Way Plug and Lead Recommendation for a Trailer
  • The Coiled Adapter # 787196 has 5 wires that run through it. A ground wire, a running light wire, a left stop/turn wire, a right stop/turn wire, and an auxiliary wire usually run to the reverse light circuit of a vehicle. For what you are doing you would be better off using a 7-Way Molded Trailer Wire Connector # H20046 since it has all 7 circuits and the brake output circuit wire has 12 gauge wire instead of the 16 gauge wire of the # 78716 which would not be sufficient.

  • What is the Wire Gauge Used in the Coiled Adapter - 7-Way Flat Pin Blade to 5-Flat # 787196
  • A coiled cable would have to be a bit thinner in order to efficiently coil and also not be bulky and heavy. But the outer cable is not as important as the wires on the inside. In this adapter, # 787196, the wires are 16 gauge. This is very common for trailer wiring accessories. Wesbar does make a good product so I think you will like this adapter.

  • Selecting Replacement LED-Type Trailer Lights for Silverlite Horse Trailer
  • Replacing older incandescent trailer lights with efficient LED versions is a great way to both increase the visibility of your trailer and pull less current through your vehicle and trailer wiring. You might even choose to add additional lights since LEDs require only about 1/10th of the power of standard bulbs. Depending on the age of the trailer there may even be LED lights available in similar sizes/shapes to your originals. Since you know your trailer uses Wesbar lights you can...

  • Can Wires on Wesbar Trailer Tail Light 403075 be Spliced to Trailer Wiring
  • Yes, you can splice the wires on the Wesbar trailer tail light # 403075. Since the light is going onto a Sea Doo trailer and will likely get submerged you will want to make sure the splices are water tight. I recommend using some liquid electrical tape # SWC50122 and heat shrink tubing # DW05451 to keep out water.
