Splicing Into the 12V Power Circuit
Tesla recommends to make a T-junction connection between the 12V auxiliary socket and its electrical
connector (Figure 6). This method is preferred because the original vehicle wiring is not compromised.

Alternatively, 12V power can be accessed from the gray 3-pin connector (Delphi 12176836) that connects
to the 12V auxiliary socket (Figure 7). The blue wire (location A) is positive 12V power and the black wire
(location C) is chassis ground.

NOTE: This 12V power circuit provides up to 12A continuous draw total (16A peak). Consider the
electrical requirements of the accessory when deciding how to splice into the circuit. Whenever power is
taken from the feeding circuit towards the 12V power socket, the 12V power socket will not be able to
provide 12A continuous / 16A peak current anymore.
