I had installed the ROADMASTER tail light wiring kit on my towed Jeep which included this jumper cable to connect the car to my RV. Somehow it dragged on the ground while towing and wore through some insulation and one wire. I was very glad to see I could order just this jumper cable to make my install as good as new. ROADMASTER helped me identify the part number and etrailer stocked them at a good price.


Comments
Its been a year, and everything is still working great. I am more careful how I support this jumper now.

Hard to find item and at a great price point! I use it to connect my 90 Suzuki to my 2009 Explorer when I tow it to the beach!




by:

Good quality. Fair price. Timely delive ry.




by:

Checked with several RV shops, marine stores, and a place that sells trailers. The trailer placed rigged up a cable for $30. Spent more than a few hours scouring the web till I found etrailer.com and not sure of the nomenclature of what I needed, emailed their customer service with a description of the application and sent a picture of the connectors and within a couple days was sent the pic of this product. I was apprehensive at first until I viewed all the pictures then I was sold and immediately placed my order. Received the product 2 days ahead of the predicted arrival date and couldn't be happier. Highly recommend etrailer.com. I have actually bookmarked the site for later reference.




by:

My review is based primarily on the service I received when calling etrailer.com. I cannot brag enough on how friendly, helpful, and efficient the representative was on the phone. I needed to purchase this product as a replacement for a component which came in a larger package/bundle I had previously purchased. I described the individual item I needed, and she directed me right to it and completed my order then and there, saving me the much larger sum of money which would have been required to purchase the entire package all over again. It was so easy. I'm very impressed with not only the inventory and products, but perhaps even more so the staff and service of this great company. I highly recommend them.




by:

We ordered tow mounts, road master tow bar and some accessories from etrailer for a 2009 Suburban. All the items arrived within a few days and packed in secure boxes. After just a little drilling the mounts went right on, the instructions are very detailed and easy to follow. I highly recommend etrailer.com for your towing needs.

Needed make to make extension for trailer lights. Which is not easy to find. Thanks to etrailer.com, I got what I needed. Easy to order on site. Delivered in a timely manner. No complaints from here!

Easy to install and needed for extending the wiring for the tow hitch.

Perfect! Hard to find this cable in local stores and etrailer not only had it, but at a great price.




by:

Product was just as described and met my needs perfectly. Needed a replacement quickly for a planned trip and item came on time as promised.




by:

Just what I needed and ordered
Love
this company and the quality of service and product I receive
Would and have recommended this site to others
Will be back shopping soon have another project in the works




by:

Exactly what I needed for towing my Jeep. Arrived quickly. The pigtail currently on there was too short.




by:

Nice and small, bunches better than the coiled cable I had before.




by:

Products were delivered promptly and were exactly what I ordered. I would not hesitate using this site again. Great service.




by:

Purchased this as a backup for the one I purchased earlier. The one that was replaced had gotten nicked when folding or tow bar.

Great service, great price.
Thanks.

  • Trailer Connector Adapter for Towing a Trailer with a Female 4-Way Trailer Connector
    I am not sure why your kayak trailer came with a female 4-way connector. In the trailer industry, the tow vehicle uses a female style trailer connector and the trailer uses a male style connector. This is the general rule. I have not heard of a vehicle coming with a male style trailer connector of any type. I have attached a photo showing what the vehicle side connector should look like and what the trailer side connector should look like. There are two solutions for this situation. It...

Both are male ends which is what you should need (the motor home and front of vehicle should have the same female connector). I have included a couple of helpful links to our FAQ articles on flat towing for you as well.

  • How to Make 12 inch 4-Way Male to 4-Way Male Adapter
    Since we don't have the exact 4-way adapter you are looking for the best option would be to use two of the # 9653P connectors and cut them both in half and then splice the two male sides together.

  • Installation Instructions for Trailer Wiring Harness 18252 for a 2008 Smart fortwo
    The trailer wiring harness # 18252 is a universal hardwire type of harness so it does not have vehicle specific instructions because it fits so many vehicles. However, the process for installation is the same for all vehicles. You will use the included circuit tester to test each wire behind the tail lights. The white wire is ground and attaches to a clean bare metal surface. Brown attaches to the running light wire. Yellow is for the left turn signal/left brake light. And green is for...

  • Availability of 8 Foot Long 4-Way Wiring Extension
    We do have 4-Way flat to 4-Way flat extension adapters available, however they do not feature a coiled wire like you mentioned in your question. I recommend taking a look at the Hopkins 4-Pole Flat Wiring Extension # HM48235. This extension measures 120 inches (10 feet) long, which is a bit longer than you need but is the closest option available. We also have a 6 foot extension loop with part # RM-300150-00. I have attached a couple short video demonstrations on these products that...

    Tow bars are not vehicle specific but the base plates are. You can use the Falcon 5250 tow bar with your 1995 Jeep Wrangler as long as you first install the correct base plates, see link. Either set will be compatible with the 5250 tow bar. You will also need safety cables like # RM-643, a lighting solution, and supplemental braking. Also check the vehicle owners manual for more information on recreational towing of the Wrangler. For lighting there are several possible options. If you...

  • 4-Way Prong Wiring Needed That is 8' Long
    If you are looking for just an extension then the Hopkins 4-Pole Flat Wiring Extension # HM48235 that you referenced is 10' long and will be exactly what you are needing. For a flat towing application we have the common 4-Way round connectors like part # HM47046 which is 8' long or for a 4-Way flat connector you would need both the part # RM-300150-00 (6') and the part # HM47004 (2'). Let me know if you are looking for something different and I can make a recommendation for you.

  • Parts Needed to Flat Tow a 2009 Chevy HHR Behind a Motor Home
    This has actually come up before and Roadmaster explained that they have not tested their base plates with the EAZ Lift tow bars so I cannot say if they will fit or not. You would need to contact EAZ Lift to determine if they have tested it with Roadmaster or Blue Ox base plates. What I recommend is using the Roadmaster base plates, # 3141-1, and using a tow bar that you know is compatible like the Falcon 2, # RM-520. You will also need safety cables like # RM-643. Next you will need...

  • Parts Needed to Flat Tow a 2009 Pontiac G6 GT Behind a Motor Home
    You can use the Demco base plates # DM9517188 for your 2009 Pontiac G6 GT. But first, you are going to want to consult the vehicle owners manual to determine if the vehicle can be flat towed and if there are any special requirements. From what I found if the vehicle has the 3.9 liter V6 motor it cannot be flat towed. But it is not clear if it can be dolly towed or not. You would need to talk to a GM tech at a dealership to determine if dolly towing is acceptable. If you find that you can...

  • Parts Needed to Flat Tow a 1993 Jeep Wrangler Behind a 2007 Chevy Suburban
    For the 1993 Jeep Wrangler, we only have base plate options (that connect to the tow bar) if the Jeep has a U-channel bumper. You can use base plates # 1409-3. These base plates are compatible with your Roadmaster Falcon 2 tow bar, # RM-525. In addition to the base plates and tow bar, you will also need safety cables like # RM-643, a lighting solution, and a supplemental braking system. For lighting there are several options. If you will not be towing often then I recommend a magnetic...

  • Parts Needed to Flat Tow a 2006 Honda Element with a Sterling Tow Bar
    The Roadmaster XL base plates, # 1541-1, are compatible with a 2006 Honda Element (not EX-P models) and the Sterling tow bar. The EX-P models just have a different design and require their own style base plates to fit. So after base plates and the tow bar, the next item you will need is safety cables if you do not already have some (the Sterling tow bar should have come with some). I recommend using straight cables # RM-645 to fit in the channels in the tow bar. Next you will need a...

  • How To Make a Trailer Wiring Harness Adapter with Two Vehicle Side Trailer Connectors

    In order to flat tow a vehicle, the very first thing you are going to want to do is consult the owners manual in the recreational towing section to determine the correct towing procedure. If you find that the vehicle can be flat towed then you will need 5 items. First you will need base plates on the vehicle being towed or the Toad. The base plates provide the proper safe and secure attachment point for the tow bar. You can use base plates # 1425-1. I have included a link to a video showing...

  • Parts Needed to Flat Tow a 2007 Honda Fit Behind a Motor Home
    To install Roadmaster base plates # 521558-1, trimming of spoiler, air dam, grille or plastic fascia may be required on some models of the 2007 Honda Fit. On the frame, at most there will be some drilling required. The 521557-1 kit that mentioned is designed to fit the Civic, not the Fit. In addition to the base plates you will also need a tow bar. The most popular tow bar option for the EZ style base plates is the Falcon 2, # RM-520. You will also need safety cables like # RM-643. You...
