2019 TESLA MODEL X wiring

Towing and Accessories
The towing package allows you to tow a trailer
with your Model X. It also allows you to carry skis, snowboards, bicycles, etc. by attaching
an accessory carrier to the hitch.
Carrying Accessories The Model X towing package has a 50 mm ball
coupling that can support an accessory
carrier.
The ball coupling is designed to support vertical loads of up to 54 kg. When carrying
bicycles or other items on the Model X hitch, always check to ensure that the maximum
weight is not exceeded. When calculating
weight, remember to include the weight of the
accessory carrier. For example, assuming the
carrier weighs 14 kg, the weight threshold is sufficient for carrying two bicycles weighing
approximately 20 kg each, or four bicycles
weighing approximately 10 kg each.
Caution: The Model X hitch is designed to
support up to 54 kg. Exceeding this
maximum weight can cause significant
damage.Caution: Do not attempt to install a
carrier on a Model X that is not equipped
with the towing package. Doing so can
cause significant damage.
To install and use an accessory carrier, the tow
hitch must be connected (see Connecting the
Tow Hitch on page 93). Then follow the
instructions provided with your accessory
carrier. Observe all regulations and legal requirements in your state/region that apply
to carrying accessories.
The Model X towing package includes the
wiring necessary for using an accessory carrier
equipped with lights (see Electrical
Connections on page 95). The package also
includes Trailer Mode software (see Trailer
Mode on page 90).
When you connect an accessory
carrier

1.Connect the wiring on the brake controller
to the appropriate locations on the 4-pin
pigtail connector included with your
Model X.
1 - Brake control output to trailer
2 - Ground
3 - Brake On Signal
4 - 12V Power (20A)
2. Remove the cover located under the
dashboard in the driver

Plugging trailer wiring into the Model X
electrical connector automatically engages
Trailer Mode (see Trailer Mode on page 90).Warning: Use only the electrical
connection designed by Tesla. Do not
attempt to directly splice or attempt to
connect a trailer

3.The current automatically sets to the
maximum current available from the
attached charge cable, unless it was
previously reduced to a lower level. If
needed, touch - or + to change the current
(for example, you may want to reduce the
current if you are concerned about
overloading a domestic wiring circuit
shared by other equipment). It is not
possible to set the charging current to a
level that exceeds the maximum available
from the attached charge cable. When
you change the current, Model X
remembers the location. If you charge at
the same location, you do not need to change it again.
Note: For 3-phase charging (if applicable
in your region), the available current
represents the current per phase (up to 32 amps). During charging, the right status
