  • Tips for Routing Power Wire of Trailer Wiring Kit for 2019 Mazda 3
  • When routing the power wire of the Tekonsha trailer wiring kit part # 118808 to the vehicle's positive battery post we don't have an exact route you'll need to take for your 2019 Mazda 3 but I can help steer you in the right direction. Basically you want to route it up to the front of the vehicle from underneath it securing it with the included zip ties avoiding anything hot (exhaust) and moving components (suspension). I attached a help article on routing the power wire for you to check...

  • Can Two Trek Electric Bikes with Fenders and Cargo Carriers be Used with the Saris SuperClamp EX?
  • I have a great solution for you. At eTrailer, we strongly recommend against using wheel-mount bike racks for bikes with fenders. There is no way to guarantee that the ratcheting hooks can secure the bike by the wheels at a 3-o'clock position on the Saris SuperClamp EX Bike Rack for 2 Bikes # SA4025F. In addition, we strongly discourage mounting a bike by any attached cargo carriers over the bike's wheels. A great alternative bike rack that avoids these problems is the Swagman E-Spec Bike...

  • Installing a Trailer Hitch on a 2016 Mazda 3 Sedan
  • Though I can confirm the EcoHitch # 306-X7303 will absolutely fit a 2016 Mazda 3, we have yet to do an install with said hitch. However, we do have an install we did with a Draw-Tite # 24912 on a 2015 Mazda 3. There will be a few subtle differences, but they do attach the same way. I included that video for you to take a look at.

  • Hitch Installation Bolts Appear to Be Too Short
  • When a trailer hitch is constructed, the manufacturers use a more malleable steel to construct the mounting flanges than what's used in the crossbar and receiver tube. This allows the hitch to flex a little bit along with the vehicle. Because of this flexibility, the mounting flanges can and do sometimes get slightly bent out of alignment during the shipping and handling process. This is very easy to fix, the procedure is outlined in the help article I've linked for you.

  • Will Installing and Using a Trailer Hitch Affect the Tire Sensors on a 2014 Mazda 3 Hatchback
  • Installing a trailer hitch such as Curt trailer hitch # C11377 will not affect the tire sensors. However, depending on what you use the hitch for the extra weight in the hitch could cause an inaccurate reading of the tire sensors but should go back to normal (if it happens at all) once the load is removed from the hitch. If you want to use the hitch for a bike rack or cargo carrier and not towing then I recommend going with Draw-Tite trailer hitch # 24914. Also, make sure the accessory...

  • Can Trailer Hitch Hardware be Greased to Resist Corrosion for a 2012 Mazda 3 Hatchback
  • The Draw-Tite trailer hitch, # 24843, uses lock washers and conical tooth washers that prevent the nuts from backing out. I would say that the use of grease is not prohibited by the instructions (see link) but that there are some other options. You can use blue Loctite, # LT37643. The blue version will allow the hardware to be removed (if ever needed) but will also protect the hardware from corrosion. The problem with grease is that it can cause other particles of dirt and things to...

  • The cutout on your frame is different from what we have seen. It does appear to be smaller. You'd want to use a dremel or rotary tool to enlarge it slightly till you can pass the bolt and spacer of the Curt Hitch part # C11377 through.

  • According to the installation instructions for the Draw-Tite Class I hitch, # 24914, you will not have to alter the bumper on your 2015 Mazda 3.

  • Installation of a Trailer Hitch Receiver In Two Separate Days or Sessions
  • The Curt Trailer Hitch Receiver - Custom Fit - Class I - 1-1/4" # C11390 you asked this question from is a confirmed fit for your 2012 Ford Fusion. It absolutely is possible to spread an installation out over two days, but you will want to be careful of a couple of things. Once you have the bolts installed into the frame, you will want to make sure that they can't vibrate loose from their location. This may mean using additional washers to ensure the flange lock nut doesn't have the...

  • Installing Curt Class I # C11377 on 2014 Mazda 3

  • Installation Instructions for a Trailer Hitch on a 2008 Mazda 3
  • We do not yet have an actual photo of the hitch on a 2008 Mazda 3. The installation instructions include a nice diagram on how the hitch will fit in relation to the bumper, and I have provided a link to those below. The existing holes for installation need to be enlarged so may be hard to see underneath the vehicle if you do not know exactly where to look.

  • Why Does Curt Say a Stabilizer Strap Is Needed for Some Hitches Carrying Bike Racks
  • Curt specifies that all non-trailer loads - bike racks, cargo carriers and so forth - should be supported with stabilizing straps. Failure to properly support these loads will void your hitch warranty from Curt. For a stabilizer strap you could use the Curt Strap part # 18050. I attached a video that shows how it installs. Basically it attaches to the trunk lid of your vehicle and to the rack and provides additional support so that the weight of the rack over bumps does not jar the hitch...

  • Is Underbody Trim Panel Reinstalled on 2023 Mazda 3 For Draw-Tite Hitch Installation
  • Yes, to install the Draw-Tite Sportframe Trailer Hitch Receiver # 24984 on your 2023 Mazda 3 you will need to remove that panel and it won't be put back into place. Hitch instructions only mention this when the hitch either prevents the panel fitting back into place or there is excessive trimming that needs to be done on the panel for it to fit back in place so it's easier to just remove it and leave it off. If you'll be using the hitch for towing I recommend installing the T-One Wiring...

  • Kats Block Heater for Mazda 3 2012 Skyactiv
  • The Kat's heater part # KH11409 plugs into one of the freeze plugs in the back of the engine block. There should be a couple different options to use, but use the rear most hole. It is recommended to use a certified mechanic for install. When installing it, you need to drain all of the coolant from your radiator, submerge the heater in coolant before energizing it, then you can install the block heater. You need to use a 50/50 blend of coolant and distilled water. I am going to attach a...

  • Where Does Wiring Harness 118420 Plug Into on a 2012 Mazda 3
  • The yellow, brown, and red refers to the wires on harness # 118420 for your 2012 Mazda 3 sedan. The wire colors used on the vehicle will not likely be these colors because there isn't a standard color code for automotive wiring. You will just need to locate the matching connectors on the driver's side that will accept the connectors with the red, brown, and yellow wires. The green wire and its connectors plug in line with the passenger's side tail light wiring. I have linked a video that...
