Also +12v use depends upon your new load (current draw requirements). For high output [more current draw] you may need a dedicated 12v supply line from the battery.
Another important detail which is missing in all the discussions is.
Lexus uses a proprietary serial link protocol do talk to all the various components. The information to turn on devices is through that link.
If you are embarking on this journey for the first time, also note that Lexus uses dual differential [l+,l-,r+,r- and no ground] audio signals which have non standard [l,r, gnd] line level ... standard audio use 1v rms as AUX in/out level. <- Ignore this stuff if you plan t rip out the OEM stuff.
