  • Installation of Zero Contact Interface Sensor Trailer Wiring Harness on 2015 Mercedes-Benz GL-Class
  • For the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT should not be installed tapping into another power supply like a cigarette lighter. The power draw needs to be directly from the battery to ensure you don't have a power issue from a fuse or other component that isn't designed for that use. Having power to your trailer wiring even when stored is not an issue and you don't want to keep turning power on and off to a controller...

  • Alternate Hardware to Install Roadmaster RM-1209-131 Anti-Sway Bar on 2015 Mercedes-Benz Sprinter
  • I typically do not recommend folks deviate from the manufacturer's installation instructions because all the development, testing and engineering work has been done with a given product installed in a particular manner. I spoke with my contact in the tech services department at Roadmaster, who told me that they haven't had ANY reports of this occurring. Changing to a grade 8 bolt and using a thicker washer would be fine. He's guessing that in this particular instance the bolts started...

  • Solution to Keep Hopkins Collapsible Vehicle Trunk Cargo Organizer from Sliding on Rubber Mat
  • The Hopkins Collapsible Vehicle Trunk Cargo Organizer # HM74113 does come with hook and loop fasteners (like Velcro) that you can add to the bottom of the legs which would help to grip a carpet floor. If you have a rubber mat then it's possible that the organizer could move around depending on how smooth it is and if there are any grooves or anything in it. I spoke with my contact at Hopkins who said that if you have a smoother rubber matt then a possible solution is to use two sides of...

  • How Does Curt Trailer Hitch # C11823 Install on a 2001 Mercedes S 600
  • The Curt trailer hitch # C11823 installs onto the vehicle using steel support plates that come with the hitch. It bolts through the spare trunk pan and to the plates which will be inside of the trunk. I have included a link to the installation instructions for you to view. If you plan on doing some towing the hitch does come with the correct ball mount, hitch pin and clip. For a ball use # 19256 for a 1-7/8 inch diameter or # 19258 for a 2 inch. For wiring, use # C59236. I have included...

  • Does the etrailer 2-in-1 Exterior Windshield and Wiper Blade Cover Have Magnets
  • The etrailer 2-in-1 Exterior Windshield and Wiper Blade Cover part # e98899 does not come with magnets, it is held in place both by the sewn in loops which wrap around the side mirrors as well as the fabric flaps which will get shut in the door jamb. It is actually pretty secure once you get both of these attachments secured. I don't think magnets would work well for a windshield cover.

  • Is Spacer Included With Curt 13018 Hitch Needed When Installing on 2001 Mercedes-Benz ML350
  • I spoke with my contact in the engineering department at Curt, who tells me that by 'outboard mounted spare tire', they mean that if the vehicle's spare tire carrier is bolted to the bumper beam, the spacer plate is needed. If it's bolted elsewhere, the spacer will not be needed. If you'll be towing with the hitch, you'll also need a trailer wiring harness like # C59496, a ball mount like # 2753 and a trailer ball like # 19260 for a 1-7/8 inch or # 63845 for a 2 inch ball.

  • Parts Needed to Install Redarc Tow-Pro Elite Brake Controller on a 2015 Mercedes-Benz G550
  • To install the Redarc Tow-Pro Elite # RED44FR on your 2015 Mercedes-Benz G550 you're going to need to a 4-Way wiring kit like the Tekonsha ZCI # 119250KIT as well as our Universal Installation Kit # ETBC7. The ZCI uses special clamps that sense when the different trailer light functions need to be activated and then it pulls power straight from the vehicle battery to power the trailer lights. This keeps you from cutting your OEM wiring or overloading your vehicle light circuits. The ETBC7...

  • Trouble Locating Cold Side of Stop Light Switch for Brake Controller on 2014 Mercedes-Benz Sprinter
  • There are some wires that are hot all of the time which is why we usually try to emphasize that the brake controller, like the Prodigy P3 # 90195, needs to be connected to the cold side of the stop light switch when installing the Kit # ETBC7. Sometimes a vehicle will not have a wire connected to the cold side of the stop light switch which is what you are finding. In that case you will simply need to install the Roadmaster Stop Light Switch Kit # RM-751475. This is typically used for...

  • 4-Way Trailer Wiring Harness Recommendation for RV that Has Separate Signal 6-Way Installed
  • Your RV has separate turn signal from stoplights so while I have a solution I can provide, it will not involve the 6-way socket you have. You would want to install a 4-way to your vehicle with the part # 119250KIT. This will allow you to keep the connector you have now and also have a 4-way connector ready for your trailers.

  • The Replacement Support Arm Assembly for Lippert 63" Short Awning part # LC97UD does not come with the motor or any wiring, you'll need to transfer the motor and wiring from your old arms. These arms can indeed be used on both the drive and idler sides. I have attached the wiring guide below for your reference.

  • Is Trimming of Bumper Required for CURT Trailer Hitch # C13102 on 2011 Mercedes-Benz GL 450
  • I contacted our representative at CURT about installing the CURT Trailer Hitch # C13102, on your 2011 Mercedes-Benz GL450. He informed me that there should be no trimming required to install the hitch even with plastic fascia. I have attached a picture of the hitch installed on a model with the decorative aluminum fascia. You will want to compare the fascia to see if it is the same size and shape. However, if the exhaust heat shields are coming in contact with the hitch, the heat shields...

  • Installantion and Compatibility Questions for Thule Apex XT4 Bike Rack
  • The Thule Apex XT 4 Bike Rack for 1-1/4" and 2" Hitches - Tilting # TH9025XT you asked about has a distance from the trailer hitch receiver hitch pin hole to the closest part of the rack of 7-1/4 inches.

The rack comes completely assembled with just an adapter to add for the 2 inch hitch receiver that uses two screws and comes with the hex wrench needed for installation. The bike...

  • Does Tekonsha Prodigy P3 Brake Controller go to Sleep When Not in Use
  • Thank you for your purchase from etrailer of the Tekonsha Prodigy P3 Trailer Brake Controller # 90195. In regards to its use, the controller can be left plugged in as it will go into sleep mode after 15 minutes of not being used. You can certainly unplug it if you like, but leaving it plugged in will not drain the battery so you definitely do not have to do that if you don't like.

  • Brake Controller Circuit Breaker Installation in Motor Home
  • A trailer brake controller such as the Tekonsha Prodigy P3 # 90195 must be installed as per the manufacturer's instructions which means a direct-from-the-battery 12V power connection. It may be tempting to consider using a nearby fuse panel for 12V power access but this is not recommended for safety reasons. Brake controllers do not have power switches, for the reason that any interruption to power for the controller could have catastrophic effects when you are towing. For the same reason...

  • How to Install Tire Cable Chains on a 2015 Subaru Outback Wagon
  • I am not sure I understand what you mean by split connector. If you take a look at the attached review video, you will see how the Glacier Cable Snow Tire Chains part # PW1046 should be installed on your 2015 Subaru Outback Wagon with 225/60-18 tires. You will first start by draping the cables over the tire and then aligning the opening towards the ground. Once you have the opening towards the ground you can then connect the cables on each side and pull to tighten them. Once they are tight...
