  • Will My Bike Rack Wobble Less if I Buy a Rack that is Made Only for My 1-1/4 Hitch and not a Combo?
  • If you have a hitch-mounted bike rack like the Curt 2 Bike Rack for 1-1/4" and 2" Hitches # C18085 with a 2-inch sleeve, it will not make any noticeable difference as far as wobble if you get a hitch specially designed to only fit your 1-1/4 inch hitch (without the adapter sleeve). One of the great features of the Curt 2 rack is that it comes with a anti-wobble hitch pin that reduces movement and noise in the hitch. This hitch pin offers extra support to your hitch when installed in your...

  • How to Remove Old Split Bushing on Roadmaster Sterling Tow Bar
  • In order to replace the bushing on your Sterling Tow Bar with a new Split Nylatron Bushing # RM-200029-00 you'll need to remove the 3/4" lock nut to remove the knuckle and slide the shaft out. From there you'll use a flat head screwdriver and needle-nose pliers to remove the old bushing. The new bushing can then be slid in and the shaft replaced working backwards to reassemble the tow bar.

  • Are Separate 12V Power Feeds Needed for Curt 4-Pole Harness and Autowbrake Trailer Brake Controller
  • You can install both the Curt 4-pole wiring harness # C56389 and the Autowbrake Trailer Mount Electric Brake Controller # 3430001 (and the required 7-way kit # ETBC7L) in your 2019 Buick Regal TourX but each one of these items must have its own dedicated power connection to the vehicle battery. I realize its no fun crawling under the car to route those power wires but this is critical for safety and for proper operation of these devices. For a worst-case example, if there were a fault...

  • Can I Mount The Replacement Switch For The Automatic Battery Disconnect In The Wheel Well
  • The Replacement Switch for Roadmaster Automatic Battery Disconnect, part # RM57ZR, is not weatherproof. One of the installation requirements of the Roadmaster Automatic Battery Disconnect with Switch for Towed Vehicle w/ Supplemental Braking System, part # RM-766, is that it needs to be protected from direct road spray. In my opinion, the wheel well would provide too much spray and the switch and/or solenoid would get wet. I have included a product description link, a video demo, and...

  • Ease of Installation for the etrailer e98863 Hitch on a 2008 Buick Enclave
  • The etrailer Trailer Hitch Receiver item # e98863, for a 2008 Buick Enclave, has a three out of ten on our difficulty to install scale. It looks like a pretty simple installation there's no cutting or trimming required. You will have to temporarily detach one of the muffler braces so I recommend having your Enclave sitting for awhile where you are going to install the hitch so the muffler and surrounding area isn't hot. I have linked the instructions and also a couple of install video's...

  • How Long Would Install of etrailer Hitch for 2023 Buick Enclave Take
  • For most people the install of the etrailer hitch part # e56YR would probably take a couple hours to install. For a dealer though I would assume maybe about the same but they might charge you for two shop hours. The charge would be based on what their current shop hour rate is. I attached a link to the install instructions as well as a video of the install for you to check out as well.

  • You are on the right track with all of the components you are planning for your 2006 Buick Terraza but there is more information needed to determine what rise/drop ball mount you would need. I attached an FAQ that details how to pick out the correct ball mount. Picking out the correct ball mount will allow your trailer to sit as level as possible. Basically you will first measure the height from the ground to the top of the receiver opening on the hitch while on level ground. Next, you...

  • Installing Tail Light Converter Part # 119178KIT to 1998 Buick Park Avenue
  • The easiest place to access the wiring that you would need to tap into is behind the tail light assemblies inside the trunk. Pull any carpet or lining away from the rear of the tail lights, and locate the wiring harnesses exiting the tail lights. Start on the drivers side. Ground the white wire to clean metal on the inside of the trunk. If you can find a factory grounding point nearby, go ahead and use it. Otherwise, use a self-tapping screw. Then, have a helper turn on the left turn signal....

  • Is there a Brake Controller Wiring Harness for Elecrical Connection on a 2006 Buick Ranier
  • Yes, your 2006 Buick Rainier will have a bundle of wires under the dash to the left of the steering column that will need to be spliced to the wiring included with the Tekonsha P-3 Trailer Brake Controller, item # 90195. This installation is the same as the one you saw in the video for the 2004 Trailblazer, and will work for the 2004 - 2006 Rainier with factory tow package. There is not a connector on your vehicle, so the wires must be spliced and the P-3 includes butt connectors for this...

Once you remove the felt liner covering the back of the tail light assembly, you will see a black connector plugged into the tail light assembly. You will simply unplug that connector to connect the wiring harness. I have attached a photo from the installation instructions showing what the tail light connector looks like. I have also attached a link...

  • Why Is A Stop Light Switch Kit Needed For A 2020 Buick Encore GX
  • The Roadmaster Stop Light Switch Kit # RM62FR is needed because the brake light switch wire of the 2020 Buick Encore GX isn't useable and this simulates the braking signal so that it can be sent out to the braking system. This allows you to see when the brakes are being applied while flat towing, which is important because you can easily verify if the brakes are activating when they shouldn't be or not activating when they need to so that you can pull over and troubleshoot the issue. A...

  • Installing Hardwire Trailer Wiring Harness On 2001 Buick Regal LS
  • Unfortunately there is no plug-in kit available for your 2001 Regal, so to install a trailer wiring harness on your vehicle it will have to be hardwired. I recommend the Draw-Tite 4-Pole Hardwire Kit, part # 18252. I have attached a link to an installation video for this harness on a Century that will be similar. You need to access the wires at the back of the tail lights in the trunk of your Regal. You can use the included circuit tester to identify the correct wires to attach the harness to.

  • Can Rear Fascia Door Be Reinstalled on 2014 Buick Enclave After Installing Trailer Hitch
  • On the 2014 Buick Enclave you will not be able to reinstall the regular fascia door to cover the hitch receiver after the hitch is installed. You would have to get the alternate from a GM dealer. I have seen that it can be expensive and it has to be painted to match the vehicle. If you plan on doing some towing with trailer hitch # 75528 then I also recommend etrailer ball mount kit # 989900. it comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a storage bag. For trailer wiring...
