2007 Yaris Sedan Radio Wiring Help

[TheJage]

Hey there,

I have a 2007 Yaris Sedan.

I have read most of the posts on here about wiring an aftermarket stereo and the wiring diagrams, but I am still confused. When I pulled the stock unit out, there were 3 connections to the stereo.

First had the wires:
Yellow
Black
Red
White
Green

Second:
Grey
Yellow
Black
Purple
Pink
White/Black
Blue
Green
Grey

Third:
Red
White
Red
Grey
Green

Everything I have read says:
12V = blue, Ground = white/black, Ignition = grey, Illumination = green, Antenna = Black, LF = Pink/Purple, RF= Grey/Yellow, LR = Black/Yellow, RR = Red White.

Is it just me or do these not match up? It seems I need wires from all 3 connections, but then, what are the extra wires for???

It may have been a bad idea, but I already cut the connectors getting ready to splice the wires onto my new stereo.

Please help! Thanks.
