• Recommended 6-Way Wiring Harness for 2013 Chevrolet Impala
  I would be happy to help you. The connector on your 2018 Aspen camper is a 6-way connector. In order to get a 6-way connection on your 2013 Chevrolet Impala you will need to start with a 4-way. For a 4-way, I recommend the # 118417 T-One Vehicle Wiring Harness from Tekonsha. This is a custom fit wiring harness and plugs directly into connection points behind the passenger's-side tail light. For the 6-way connection, you want the # ETBC6 Universal Installation Kit. This includes all...

• Can Redarc BCDC Charger Be Used with 7-Way Connector to Charge Trailer Battery
  The Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D that you referenced could physically be installed so that it uses 12V power from the 7-Way connector on your truck, but it's not going to allow for ideal operation. The problem is that typical trailer connectors use smaller 10 gauge wiring that just isn't capable of allowing enough power to pass through to really charge a battery up. Since this is exactly what you would want to use the BCDC charger for, using it with the 7-Way...

• What to do With the Extra Wires on 4 to 7 Pole Adapter for a Camper Trailer
  On the Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector, # 30717, the extra wires can be taped off, tied up with a cable tie, and tucked out of the way if not in use. I would attach the white ground wire to an existing grounding point or the vehicle frame even if you do not intend on adding a brake controller (which is what the other wires are for). You would then attach the vehicles 4-Way into the 4-Way end of the adapter and plug your trailer connector into the 7-Way for lights...

• Recommended Wiring Connection Adapter for Jeep 4-Pin to Trailer 7-Pin
  If all you want to do is go from the 4-way trailer connector to the 7-way without adding functions, all you need to do is use an adapter like # 30717. You will simply plug in the 4-way and then connect the white ground wire with ring terminal to your vehicle frame. The ground needs a bare metal to metal connection free of debris and corrosion. The other three wires on the adapter can be left disconnected. The only thing to double check since you have a boat trailer is that you don't...

• Adding a 7-Way Trailer Connector and Brake Controller to a 2003 Toyota Tacoma with 4-Way Connector
  It does sound like a 4-Way flat was added to your 2003 Toyota Tacoma. But that is a good thing because it will be needed to install the 7-Way. To add the 7-Way (if using an in-cab brake controller) you will need installation kit # ETBC7. This provides the 7-Way, still retains the 4-Way as well, and has the wiring and accessories needed to install the brake controller. I have included some links to the right that show and explain this installation for you. For a brake controller I recommend...

• Replacement OEM 7-Way Trailer Connector for 2008 Honda Ridgeline
  I believe the 7-way on your Ridgeline plugs into a US car connector. You can check this by unplugging the damaged 7-way connector from the wiring harness that plugs into the back of it, and comparing what the connector looks like, compared to the left-hand panel in the photo I've provided for you. If they match, you can use the # HM40975 as a replacement for your 7-way. We don't have the OEM Honda part, but this connector will provide you with a functional 4-pole, as well as the 7-way....

After this simple connection, this adapter will be able to power the trailer's basic signal lights. In order to activate the 12V pin on the connector and power the trailer's electric brakes, the additional wires coming out from the adapter will need to be connected. If you...

• What Type of Trailer Wiring Would 2017 Jayco Sport 10SD Have On it
  It was somewhat hard to see in the pictures I found of the camper online but I was able to see a 4-way so you should be good since your Highlander has one. You might contact the dealer and verify before you drive as the owner could have installed a 7-way in place of that. In that case a simple 4-way to 7-way adapter part # 30717 would be an easy adapter to bring with you just in case.

• Where Do the Extra Wires of the 4-Way to 7-Way Adapter 30717 Run To
  The additional wires of the 4-way to 7-way adapter # 30717 are white for ground, yellow for reverse light or auxiliary, blue for brake output, and black for 12 volt accessory. To activate each of these circuits only requires you to run the wire to the proper location. The blue wire runs to the blue wire of your brake controller. The black wire runs to the positive post through a circuit breaker like part # 9510. The yellow wire would need to tap into the power wire for the reverse lights,...

  For your specific application, you can simply connect the Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector, # 30717, and mount it with # 18138.

  I have exactly what you need to add a 7-way trailer connector to a 2016 Honda Odyssey.

• Installing a Trailer Battery Charge Line from Vehicle Trailer Connector
  To charge your trailer battery when you look at the 7-way trailer-side connector the 11 o'clock pin will mate up to your 12V signal from your vehicle. With most trailer connectors like # H20043 this will be the black wire. That black wire simply connects using 10 gauge butt connector like # DW05745-5 to 10 gauge wire sold by the foot # 10-1-1 which will connect to your trailer battery positive terminal. As you stated the negative terminal of the trailer battery will be connected to the...

• 4-Way to 7-Way Adapter Recommendation for Towing Pop Up Camper
  Most likely what you would need is the part # 30717. This has a 4-way on one side of the connector that would get plugged into your Explorer and 7-way connector on the other side for connecting to your trailer. This 7-way is a 7-way blade style connector which is different from a 7-way round, but since the overall shape of the connector is round the terms get confused frequently. Since a 7-way round is typically found on heavy duty trailers, and RV style trailer almost always have a...

• Options for Installing 7-Way Trailer Connector on 2004 Ford F150 Equipped with 4-Pole
  Although the # 30717 will work, I have a better suggestion for you. If your F150 is the New Body style, use part # 118247. If you have the Old Body style, use # 118242. Either connector will plug inline with your existing trailer connector, allowing you to retain the function of your existing 4-pole. Either kit includes the necessary fuses and relays to activate the remainder of the tow package circuits. Granted, this is a more expensive option, but it will be a very quick and easy plug-and-play...

• How To Add Tekonsha Brake Controller To 1999 Lexus LX470 With Factory Tow Package 4-Way Connector
  My research shows that the tow package for the 1999 Lexus LX470 includes the receiver hitch with the wiring harness for a trailer hook-up which is the 4 pin connector that you see. Since your LX470 did not come with a factory installed 7-way trailer connector, neither the wiring harness nor the plug will be there so there is nothing to find. You will be installing all the wires needed for a brake controller and power yourself. Because your LX470 already has the 4 pin connector all...

• All Trailer Lights Blink with Turn Signals Engaged
  The issue you described sounds like a ground problem as is the case for most sporadic lighting functions. In order to fix this you will first want to start with the lighting assemblies. They will either ground through a single wire or the mounting hardware. Regardless, you will want to remove either and sand down the surface before attaching. Once this is done you will then need to do the same with the trailer connectors for both the vehicle side and trailer side. Repeat the above process...

• Trailer Lights are Not Working with 4-Way to 7-Way Adapter Plugged Into 2011 Ford Escape

I have included a link to our wiring FAQ article that shows diagrams of how various connectors should be pinned. If you are still not getting lights test the 4-Way on the vehicle with a circuit...
