I'm trying to put my 2 12" subs, amps, and maybe change front rear speakers.

The only thing you would be looking for at the stereo would be an antenna output if present (factory amp or power antenna), you don't need a wiring diagram for that just a DMM.
And maybe a second battery and a split charger, there's no way your existing battery/alternator combo will handle more than 1 amp and sub.

	LF Speaker (+)		PINK
	LF Speaker (-)		VIOLET
	RF Speaker (+)		LIGHT GREEN
	RF Speaker (-)		BLUE
	LR Speaker (+)		BLACK
	LR Speaker (-)		YELLOW
	RR Speaker (+)		RED
	RR Speaker (-)		WHITE

So no changes there then, they've been using those colours since at least the 1980s.
They also list black as the battery supply and black as the antenna, with grey as ACC and brown as ground.
I would question the battery supply and guess it was blue / YELLOW.
I also have a sneaky suspicion from a Previa I Bluetoothed the other week that antenna is BLACK/ red.
