Model 3/Y 12V Power Circuit for Third-Party Accessories,
CD-19-17-001 R5
This Service Document supersedes CD-19-17-001 R4, dated 08-Mar-2023. This new revision, R5,
updates the information on power availability. Each content change is marked by a vertical line in
the left margin. Discard the previous version and replace it with this one.
All 2017-2023 Model 3 and Model Y vehicles are equipped with a 12V power socket which is located in the
center console's rear compartment (Figure 1).
NOTE: This procedure provides instructions for Model 3 and Model Y with the first generation center
console (Model 3 vehicles built before approximately October 2, 2020, Model Y vehicles built before
approximately December 8, 2020). For instructions for Model 3 or Model Y with the second generation
center console (Model 3 vehicles built on or after approximately October 2, 2020, Model Y vehicles built on
or after approximately December 8, 2020), refer to CD-20-17-002, "Model 3/Y 12V Power Circuit for Third-
Party Accessories, Second Generation Center Console".
The purpose of this power socket is to provide a switched power source that reduces the risk of vehicle
damage due to improperly installed third-party equipment. Only when a more permanent installation is
required should the circuit that feeds the power socket be used. This document is intended to help locate the
recommended 12V power circuit, and provides informational support to individuals looking to safely splice
into the 12V power circuit.
CAUTION: Splicing into the 12V system is done solely at the user's risk and can result in increased
draining of, or potential damage to, the vehicle or 12V battery. Potential effects of modifying Model 3/Y with
third-party components can include, but are not limited to, reduced driving range and increased
electromagnetic interference (EMI).
CAUTION: Always refer to the Service Manual for the most up-to-date instructions on disconnecting
and reconnecting 12V power and removing and installing center console trim components. The instructions
in this document may not be applicable to the particular vehicle you are working on due to build date,
configuration changes, market region, etc.
