Pick up a cheap multi meter.....?
Or try this:
This is for the 6 speaker system....
Harness behind the HU:
Gray=ACC Power
Blue/Yellow=Constant Power
Brown=Ground
Pink=Front Left +
Purple=Front Left -
Lt Green=Front Right +
Blue=Front Right -
Black=Rear Left +
Yellow=Rear Feft -
Red=Rear Right +
White=Rear Right -
For the tweeters in the Front doors:
Left:
Red/Blue=Left side + input
Pink=Left side + output (then goes to woofer + side)
Blue=Left side - input
Purple=Left side - output (then goes to woofer - side)
Right:
Red=Right side + input
Lt Green=Right side + output (then goes to woofer + side)
White=Right side - input
Blue=Right side - output (then goes to woofer - side)
But honestly the meter is the way to go to be sure.

Best answer is get one of the Toyota 93+ adapter harnesses. It has everything clearly labeled out, and when I installed my Pioneer deck, the colors even matched, making it brain-dead simple.
