-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.
