Subaru Vehicles with the 6.2" Display will need some specific modification. The steering wheel button signals need to be combined moved to the 28-pin backup camera harness. Make the connections as follows:
-Cut the black, orange, purple, and the brown wires from the ATOTO direct wire adapter, 28-pin connector. Discard the 28-pin connector.
-Cut the Pink, Green, and Gray wires from the small white connector on the 28-pin adapter (this is the Maestro SW connector)
-Splice the wires as follows:
ATOTO Direct Adapter | 28-pin backup camera adapter |
Brown | Gray |
Orange | Green |
Black | Pink |
Purple | No Connection - Leave disconnected |
-For the 2016-2022 BRZ, pin 9 on the 28-pin connector must be connected to an Amp Turn-on signal to turn on the OEM amplifier for the door speakers. This is the blue wire on the 28-pin connector. Cut this blue wire and splice it to the blue Amp wire on the ATOTO direct wire adapter. There are 2 blue wires. The wire on the AM/FM adapter is different so connect it to the other blue wire.
-To install, connect the 6-pin connector between the ATOTO direct wire adapter and the 28-pin backup camera adapter.
