Accessing the Trailer Hitch

Accessing the Trailer Hitch Assembly

The Cybertruck trailer hitch assembly is located behind the rear fascia of the vehicle, under the tailgate. Your vehicle is not equipped with a ball mount, which must be purchased separately based on your towing needs.

The trailer hitch cover is attached to the body of the vehicle with three turn clips. Use a flat trim tool or non-marring screwdriver to partially turn and unlock the clips, then remove the trailer hitch cover and place it in a secure, dry place. Once removed, you can see where the ball mount can be installed.

When not actively towing, keep the cover installed to prevent dirt and debris from entering.

Note

The maximum permissible rear overhang for the coupling point is 49 in. (1.25 m), measuring from the center of the rear tire toward the hitch receiver.

Note

Always attach safety chains when towing. See your trailer Owner's Manual for more information.

Ball Mount Specifications

A ball mount must be purchased separately based on your towing needs. The Cybertruck hitch receiver supports a 2 in. (5 cm) ball mount. Follow the ball mount manufacturer's instructions for more information.

Note

Refer to the manufacturer's instructions to properly maintain the ball mount.

Electrical Connections

Cybertruck is equipped with a combination electrical outlet, located near the hitch assembly, that supports two types of commonly-used trailer plugs without needing an adapter:

7-PIN - SAE J2863 - for heavier trailer loads requiring their own braking system.
4-PIN - SAE J1239 - for light trailer loads requiring lights only.

Regulations require that all trailers, at a minimum, are equipped with taillights and turn signals. These are provided on the 4-pin connector, which is adequate when pulling a light load. For heavier loads, the trailer must also be equipped with brakes, available on the 7-pin connector.

Plugging a trailer's wiring into either electrical outlet automatically engages Trailer Mode (see Trailer Mode).

Note

Use one outlet only according to your trailering needs. The covers prevent you from opening both outlets simultaneously.

Loss of trailer lights when towing may be the result of a fault in the trailer wiring or excessive power consumption by the lights connected to the trailer output(s). When this occurs, the touchscreen displays a red Trailer Mode icon. Fix any issues with the wiring and/or reduce the number of lights connected to the trailer output(s), then turn Trailer Mode off and on to try again.

CAUTION

Always ensure that the trailer's electrical cable does not contact or drag on the ground and there is enough slack in the cable to allow for turns.

Warning

Before towing, it is the driver's responsibility to ensure that all electrical connections are working, all trailer lights are operating as expected, and the braking system is fully functioning. Cybertruck does not detect faulty electrical connections. You must perform manual checks. Failure to do so can result in property damage, personal injury, or death.

Warning

Use only the electrical connection designed by Tesla. Do not attempt to directly splice or attempt to connect trailer electrical wiring using any other method. Doing so can damage the vehicle electrical system and cause malfunctions.
