Ground Wire on Curt T-Connector for 2018 Mazda CX-9
The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56338 does not have a separate ground wire outside of the connector. You do not need to find an additional ground you will simply utilize the integrated ground in the quick connect just like the power for the converter. It is simply a plug and play harness. Connect quick connect to vehicle side harness, mount the converter, and run the 4-way to your desired location...don't forget the fuse on the power wire.

Why Does Trailer Wiring Harness Need to be Connected to Battery on a 2010 Mazda CX-9
Trailer wiring harness # 118520 for the 2010 Mazda CX-9 is a powered converter. This means it requires a direct connection to the vehicle battery to power the trailer lights. The T-connectors provide the proper signals to the converter and trailer lights. The powered converter is required in order to protect the sensitive wiring on the vehicle. If there were a short it would blow the fuse or converter and not damage the vehicle electronics. The harness will not work unless it is connected...

Why Can't Curt Trailer Wiring Harness be Powered w/12 Volt Power Outlet at Back of 2011 Mazda CX-9
Using the 12 volt power outlet certainly would make the installation of trailer wiring harness # 56016 easier on your 2011 Mazda CX-9. But there are several reasons why it should not be installed using that outlet. The reasons are that doing so will void the wiring harness warranty because it is not tested or designed for that type of installation. The circuit for a power outlet could be overloaded by the draw of a trailer wiring harness. And if attached to a power outlet you lose that...

Rhino Rack Crossbar Install Locations On 2019 Mazda CX-9
I spoke to Rhino Rack about using the Rhino-Rack RVP Roof Rack for Fixed Mounting Points part # RRRVP51 on a 2019 Mazda CX-9 and they stated you must use the forward and middle mounting points. The last mounting point is only used when there are three crossbars. The crossbar spread if using the first and last mounting point would be too large for most accessories.

How Do I Get the Smaller Bolts Started on the Curt 13575 Hitch on my 2013 Mazda CX-9
The Curt Trailer Hitch Receiver part # 13575 uses a M8 - 1.25 thread pitch bolt for the smaller size. Since you have attempted to use the brush and lubricant process and have not been successful you will need to get a tap to clean it out. Get a M8 - 1.25 tap from a local hardware or parts store and this will solve the problem. It is unfortunate but we run into this a lot in our area because of the rust our vehicles tend to get combined with the dirt roads we have makes a mess sometimes....

How to Find Reverse Light Circuit on a Vehicle that Has Reverse Lights Mounted in Hatch
Between the hatch and the door frame will be a wire loom in a rubber conduit that will be carrying the reverse light circuit. What you will want to do is peal back the conduit so that you can test the wiring there for a circuit with a tester like part # PTW2993 that only sees voltage when the reverse light circuit is activated. Once you find that circuit you will want to trace the wiring back somewhere on the door frame side to a place that allows you to easily access it. Most likely this...

Installation Lift Recommendation for Curt Wiring Harness # 56016 on a Low Sitting 2011 Mazda CX-9
I have a solution for you below, but you could go to a local garage and see what they say, more than likely they will not allow it because of liability reasons. The might offer to install it for you at a price. We do offer car service ramps like the Race Ramps # RR-XT-2 or the more economical for occasional use the FloTool # FT11912MI. Your 2011 Mazda CX-9 weighs up to 4,546lbs so you will want to keep this in mind while looking at ramps capacities. Both ramps will work for helping...

The T-One Vehicle Wiring Harness with 4 Pole Trailer Connector, # 118520, requires a direct connection to the battery.

Why Does Trailer Wiring Require Power Wire Ran to Vehicle Battery
Not all vehicles can handle the additional amperage draw of the trailer taillights on the vehicle taillight circuits. Those vehicles need setup that draws power from the battery. Some vehicles have higher rated circuits that can handle this, and others need to have the power drawn straight from the battery to protect the taillight circuits. If you were to instead draw the power from the outlet you mentioned you would be bypassing the circuit protection mentioned and it would void the warranty.

Does a Power Wire Need to be Run to Battery to Install a Curt Wiring Harness on a 2012 Mazda CX-9
Yes, you will need to run the power wire from the Curt Custom Fit Wiring Harness # 56016 to your battery. The connections to your tail light wiring harness are very much plug and play as they will just connect in line with your tail light connectors. The reason you need to run the power wire to the battery is because the # 56016 uses your tail light circuits as signal wires and actually powers the tail lights of your trailer with the power it draws from the battery of your 2012 Mazda...

Alternate Wire Routing For T-One Harness On 2012 Mazda CX-9
I have attached a link to an installation video on a 2012 Mazda CX-9 like you own. When all of the access to the tail lights is done in the rear cargo area, it can be difficult to find a place that allows you to run the 4-way connector on the T-One Harness, part # 118520. As they show in the video, when the T-one harness is not being used, you can just roll it up and stow it out of the way in your rear cargo area. This protects it from being damaged and also from corrosion. If you choose...

Is it Necessary to Torque Hitch Bolts with a Torque Wrench on a Trailer Hitch for a Mazda CX-9
Yes you should torque the bolts down properly with a torque wrench. Torque wrenches can be found at any store that carries a good selection of automotive tools.

How to Know Correct Torque Values for Hitch Installation Hardware for Curt Class III Hitch C13284
Trailer hitches we sell always include the appropriate hardware kit and instructions that specify the torque values for the fasteners.

Can a Hitch be Installed Over New Undercoating on a 2015 Mazda CX-9
I recommend scraping away the undercoating where a trailer hitch makes contact with the frame on your 2015 Mazda CX-9. Sometimes undercoating can be quite thick and it can cause some fit issues when installing a hitch so it is best just to scrape it away with a small chisel or putty knife (or similar tool). I have linked a video showing an example installation of hitch # 13575 for you. The recommended ball mount is # C45030 with a 1 inch rise/2-1/4 inch drop. If the ball mount does not...

How Do I Run the Battery Lead of My T-One Wiring Harness # 118520 on my 2011 Mazda CX-9
I can describe to you how to run the battery lead on this T-One Vehicle Wiring Harness, part # 118520, but at this time we do not have a video to show you how to do it. Usually in the floor boards of vehicles there are holes that have rubber grommets in them that you could run wires through. Try looking in the threshold, trunk floor panels and trays or pulling back some of the carpet and looking for a black, circular rubber grommet. You should be able to use a razor or x-acto knife to...

You will still be able to use the hands free lift gate feature on your 2021 Mazda CX-9 with the Curt Trailer Hitch Receiver # C13284 installed, but you will need to put your foot on either side of the receiver and move it in and out until you find the sweet spot of the sensor.

Does Tow Ready T-One Connector # 118520 On A 2008 Mazda CX-9 Have A Constant Current
The Tow Ready T-One Connector # 118520 for your 2008 Mazda CX-9 will have a constant supply of power whether the vehicle is running or not since it is connected directly to the battery. However, it will not cause a drain on the battery because the trailer wiring circuits are not active when not in use. For example, the only time a draw is placed on the power wire is when the stop, turn, or taillight circuit on the vehicle is activated and the lights on the trailer are drawing amperage. I...
