Please don't take offense but its actually pretty easy to find if you do a little digging. People tend to get pissed at this question I think. I think it is the same as 2012 and up. I found a couple of posts on toyotanation and right off of google. This is an example that might be wrong:
Radio Battery Constant 12V+ Wire: Blue/Yellow
Radio Accessory Switched 12V+ Wire: Gray
Radio Ground Wire: Brown
Left Front Speaker Positive Wire (+): Pink
Left Front Speaker Negative Wire (-): Violet
Right Front Speaker Positive Wire (+): Light Green
Right Front Speaker Negative Wire (-): Blue
Left Rear Speaker Positive Wire (+): Black
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Red
Right Rear Speaker Negative Wire (-): White
I am starting an install right now so I might come back and confirm if these colors are even in the harness. Also I found some harnesses for sale for 1987 and up! Could Toyota have kept the same harness forever? The internets are reliable right?
