  • 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...

  • With Running Lights or Brake Lights On Turn Signals on Trailer Alternate
  • Tail light ground wires are usually white so that doesn't seem odd. This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The...

  • Recommended Replacement 4-Way Connector For 1960 Trailer
  • We do offer flat 4-way trailer connectors. I recommend the Wesbar 4-Pole Flat Connector w/ Jacketed Cable, part # W787264. You would need to cut the connector off of your trailer and test the wires on the trailer for function using a 12-volt power source and a circuit tester like part # 3808. I recommend using a junction box like part # 38656, to protect the wiring. For ring terminals I recommend part # DW05702-1 for 14-16 gauge wires and part # 44-5310A for 10-12 gauge wires. I...

  • Replacement 5-Way Flat Trailer Side Connector for a Boat Trailer
  • It sounds like you have a version of a 5-Way flat wishbone harness like # W002290. A wishbone harness will have 2 running light wires attached to one running light pin. White is ground, the two brown wires are for running lights, yellow is for left turn and brake lights, green is for right turn and brake lights, and blue is for a reverse electric lockout solenoid. Since the wires on your trailer do not match up you would have to trace each wire back to determine the functions. Or...

  • Troubleshooting Trailer Right Stop/Turn Signal and Running Lights Not Functioning
  • At worst it sounds like you blew a fuse if after you connected the red wire from the part # 403356 to the brown wire from your trailer. The brown wire of your trailer wiring is most likely the running light circuit and would get connected to the brown wire of the # 403356. One thing you can do is test the trailer wiring connector of your tow vehicle for voltage with a circuit tester like part # 3808. You will need a buddy to apply the taillight functions while you test the connector....

  • Towing a Motorcycle Trailer with 4-Way Square Connector with RAV4 with 4-Way Flat Connector
  • If you want to be able to tow the trailer with the RAV4 and with the motorcycle you are going to have to wire in a second connector on the trailer to match the 4-Way flat on the RAV4. The issue is that trailers designed to tow with motorcycles will likely have turn signals separate from the brake lights. The 4-Way flat on your RAV4 has combined turn signals and brake lights. This will require a special converter, # 118158, to maintain the separate circuits on the trailer. First,...

  • Square Trailer Tail Lights with a Plug Connector for a Shorelander Trailer
  • All of the similar trailer tail lights like # 2423056 either have blunt cut wires or you just insert the wiring to the backs of the lights. None have a plug. What you could do is use light # 2423056 (and # 2423006 for the left side) and splice the plug from your old lights to them. You would need to make sure the connection is water tight by using some heat shrink tubing such as # DW05744-5.

  • Troubleshooting Trailer Lights That All Go Off When Brake Pedal Is Pressed
  • The problem you are having with your trailer lights sounds like a ground wire problem. The first thing I would check is the wires. Look for any place you have a loose ground or if there is corrosion or dirt present that would not give you sufficient ground. If you have a tilting trailer bed or tongue you will need to run a jumper wire from the tongue to the trailer bed to make sure you have a solid ground. The next thing I would suggest to check is the harness you are using. You will...

  • Are Wesbar Trailer Lights # 403076 and # 403026 Matching Left- and Right-Hand Lights
  • Yes, you are correct that the two Wesbar submersible trailer lights # 403026 and 403076 that you referenced are intended for use with one another. A product video is linked for you. The screws may appear to be different colors due to variations in the lighting during photography.

  • 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 housing, or provide a photo of the remaining lens 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...

  • 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.
