• Solution for Trailer with 6-Way Square Connector to Be Towed by Truck with 7-Way
  The only solution we are going to be able to provide for you is to build an adapter like you mentioned or do what most people do and replace the connector you have on your trailer with a standard 7-way so that it will work with your truck and most other tow vehicles out there. The square 6-way you have is pretty uncommon and typically comes with an adapter from the trailer manufacturer to attach to a 7-way, but in your case I would just remove it and install a # H20046 in its place so that...

• Running Lights Do Not Work on Yakima Rack and Roll Trailer Pulled with a 2008 Saturn Vue
  The first step I would take is to check the vehicle side and trailer side connectors for any corrosion or dirt build up that could cause a bad connection and clean it out. If the connectors look clean, then you should use a circuit tester, # 40376, to check the trailer connector on the back of your 2008 Saturn Vue. Make sure you are getting a signal at each pin when that function is activated. I have attached a video of my co-worker testing a 4-flat trailer connector for you to reference....

• 6-Way Motorcycle Trailer Connector that Doesn't Require Mounting
  How does a 6-way SQUARE sound? Based on what you described the part # 37995 would be your best option as it comes with both sides of a 6-way connector that neither require mounting permanently to the motorcycle or trailer. The reason I recommended this is that there are no 6-way flat connectors and the round ones are designed to be mounted on the vehicle side. I attached a review video for this for you to check out as well.

• Recommended Replacement Wiring for 1996 Dutchman Duck with Obsolete Wiring Harness
  Thank you for the picture. If the contacts on your trailer connector are like those on the Hopkins 6-Pole Square Connector Kit # 37995 then you can use 1/2 of this kit to replace your trailer's damaged connector and also Hidden Hitch adapter # 30104 to join it to your 4-pole-equipped vehicle. If this is not your connector then your best bet is to re-wire the trailer with a new 4-pole connector to match what is on your vehicle. You can use a junction box like # 38656 to join the existing...

• Troubleshooting Flashing Trailer Lights After Replacing 6-way with 4-Way
  It sounds like you wired up your new 4-way wrong. What you will want to do is use a 12-volt battery and jumper wire to test all of the wires of your trailer so you can determine their function and then wire up the trailer to your new 4-way according. The white wire of your 4-way will be the ground, brown will be running lights, the yellow will be left turn/brake, and the green right turn/brake.

• Looking for Adapter For 6 Pole Square Trailer Connector on Dutchman Camper
  It probably wouldn't work. Jayco used a proprietary harness that most likely wouldn't fit. The 6 pole square harness is pretty much obsolete at this point, your best bet would be to cut it off and replace it with a more common trailer connector. In the photo, it looks like there's only 4 wires on the wiring harness. If that's the case, you could just use # 18004. If the wiring harness has 6 or 7 wires, I'd recommend using a 7-way connector like part # A7WCB, as it's what's most commonly...

• Replacing Trailer Connector Wiring for Rockwood A122 A-Frame Trailer with 6-Pole Square Wiring
  Instead of replacing both the 7-Way blade-style connector as well as the 6-Pole square connectors, # 37995, I recommend using a 7-Way connector and junction box to make the connections for your trailer. This will eliminate the additional, unnecessary connection at the 6-Pole square connectors. The 7-Way connector I recommend is the Hopkins 7-Way Molded Trailer Wire Connector with 6 Foot Lead # H20044. This connector will provide power for left turn and brake signals, right turn and...

• 7-Way Trailer Connector for a Truck that has a 4-Way Flat Connector
  Are you sure it is a 6-Way and not a 7-Way blade style such as # 37185? The center counts as a pin. I have not heard of a 6-Way blade style connector, not to say that it doesn't exist but I haven't seen one myself. There might also be a way to add a 7-Way to the truck without having to cut or splice anything. If you can tell me the year, make, and model of the truck I can determine if there is a 7-Way that will work other than a hardwire option.

• Adding a 4-Way Trailer Connector to the Back of a Honda Goldwing
  The trailer connector on your Honda Goldwing is set up for a trailer with separate circuits meaning brake lights and turn signals are on different circuits. The trailer that you have has combined circuits; the brake lights and turn signals are on the same circuit. So all you will need is a separate to combined converter with a 4-Way flat connector such as # 119178KIT. On it, the white wire is ground, red connects to a brake light wire, brown connects to a tail light wire, yellow connects...

• How to Make a 6-Way Square to 4-Way Flat Trailer Wiring Adapter
  The 6-Way square trailer connector is not used by a lot of trailer manufacturers. A lot of Jayco trailers may have them but mostly you come across the 4-Way flat, like what you have on your trailer, and the 7-Way blade for RV applications. What I recommend is to convert the 6-Pole on the Monaco to a 4-Way. You can do this very easily by removing the 6-Way plug, and then testing the wires for function using a circuit tester like # 3808 if needed before installing them in a new 4-Way,...

• Troubleshooting Jayco Popup Camper Brakes and Tail Light Turn Signals
  Your trailer light functioning sporadically and the lack of function at other times leads me to believe there is a power issue. It sounds like there is a ground connection issue, but it could also be that there is a power supply issue. I recommend testing your wiring using an incandescent circuit tester like # PTW2993. Some testers will utilize LED lights that don't draw the same power as incandescent bulbs so they may give you a false reading on power. Double check the ground on your...

• Connecting a Coachman Pop-Up Trialer with 6-Way Square Connector to a Vehicle with a 7-Way RV
  To use your trailer with a vehicle that has a 7-Way connector installed on it you would be best suited to just use the Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End, item # PK12706, and hard wire it directly to the wires on the trailer. You will then have the functionality needed to provide power to the trailer brakes and have power to maintain a battery on the trailer if it is so equipped. Another advantage is that you will have no need for an adapter between...

• 6 way square to 4 way flat connection not working on 1997 Dutchman Pop-UP Tent Trailer
  As long as your vehicle is wired properly, Green right turn and stop, Yellow left turn and stop, Brown running lights and White ground, then you will have to figure out how the trailer is wired. If the adapter you are talking about was purchased and not hard wired then it could be the 4-way flat to 6-way square adapter for a Jayco RV, item # 30104, and those adapters are wired differently than most other trailers with 6-way connectors and this could be why your lights are not functioning...

  I looked up the Escapade motorcycle trailer and it showed the six wire colors as being: White - Ground Brown - Taillights Yellow - Left Turn Green - Right Turn Red - Brake Circuit Black - Accessory Terminal on Bike You will want to use a circuit tester like part # 40376, and test the function of the four wires on your motorcycle. They will most likely be ground, taillights, left turn/brake, and right turn/brake. You will want to wire the black wire on the trailer to the accessory...

• Converting a Trailer with a 6 Square Connector to a 4-Way Flat Trailer Connector
  If the trailer is a Jayco trailer, you will just need Adapter # 30104, to go from the 4-Way flat on the 2006 Honda Odyssey to the 6 square on the trailer. If the trailer is a different brand, this adapter will not work. Instead, you will need to convert one of the connectors to be compatible with the other. If you convert the trailer, the other 2 functions on it will be lost unless you converted it back again. If you converted the vehicle, it will only be compatible with trailers that...

• Finding a Reverse Light Wire to Tap Into on a 2014 Hyundai Santa Fe for Trailer with Surge Brakes
  You will need to add a 4-Way to 7-Way adapter such as # 37185. The 4-Way will plug right into this adapter. Then you will ground the white wire to the frame. The blue wire you will not need since the trailer has a surge coupler. The black wire is for 12 volt power which you may or may not need. And the purple wire is for the reverse lights. There are a couple of possible places you can find access to the reverse light circuit. It is possible that there is a reverse light wire bundled...

• Trailer Hitch Wiring Recommendation for a 1998 Jayco Pop-Up Trailer
  Yes, you could use the 6-Pole Square Trailer Wiring Connector Kit # 37995 on your 1998 Jayco Pop-Up trailer.

By doing this you will lose 2 functions of the trailer wiring, most likely one of them being a 12-volt power source.

• 6-Way Trailer Wiring Harness on an Escapade Trailer Towed by a Motorcycle
  The red wire should be brake lights and the black wire 12 volt power. But since there is no standard for wire color, it could be the other way around. The best way to determine the functions of the wires on the bike side would be to use a circuit tester such as # 3808. After you verify the functions on the bike side you can trace the wires from the trailer connector to where they terminate on the trailer to determine its functions. From what I have learned there is a power wire on the...

• Troubleshooting Possible Trailer Ground Problem on Jayco Pop-Up Camper
  What you describe sounds like a ground problem. With the running lights on, full power is being sent through the lighting system and that's when the problem would manifest itself. If the prong for the ground connection broke, it would certainly explain the problem you're having. If it's the actual prong from the connector that broke off soldering it wouldn't be strong enough, I'd recommend replacing the adapter with part # 30104. Be sure to check the grounds on the pop-up as well....

• 7-Way Recommendation for 2001 Coachman Clipper Pop Up
  A standard 7-way is going to work just fine on your trailer. That converter circuit will be for a 12 volt power source which a 7-way is going to have on the 1:00 pin. For the trailer side you would want the part # H20043 and you would be good to go.

• Troubleshooting 4-way Wiring on a 2001 Ford F-150 and 6-way Wiring on a 1989 Jayco J Series Trailer
  I would suggest checking all the fuses on your vehicle and make sure they are in proper working order. Then using a circuit tester like part # 40376 to test the signal at the truck 4-way and make sure that the trailer is getting the proper signal when the functions are activated. If you are not getting the proper signal from the 4-way a replacement kit for your truck would be Curt # C55256. This wiring harness is a T-one style that plugs directly into your OEM wiring harness.

• Troubleshooting 6-Pole Square Connector Compatibility with 4 Wire System
  If the square connector is the same, then you will simply need to match functions on the 6-Pole Square Trailer Wiring Connector Kit (Car and Trailer Ends) # 37995 for proper connection.

Then, wire the pigtail wires on the other end of the trailer end connector to the Pollak 5-Pole, Round Pin Trailer Wiring Socket, part # PK11502.

• How to Install the Hopkins 4 Pole to 6 Pole and 4 Pole Wiring Adapter # 37175 on a 2002 Dodge Ram
  Since you have a battery on the trailer you will want to use something larger than a 4-Way connector. A 4-Way will only supply lighting on your trailer. It will not be able to provide a wire to charge your trailer battery. I would recommend to use the Hopkins 4 Pole to 6 Pole and 4 Pole Wiring Adapter, part # 37175. This adapter will install on your vehicle and allow you to have a 6-Way connector and also a 4-Way connector. You would plug in the 4-Way on your vehicle to the back of this...
