I have one of these laying around so thought I'd put it on the bench and verify the basic wiring. Here's the unit in question it came standard in the 1997-2001 ES with the Pioneer head unit and changer.

I only have a cut harness so I can't detail exact specs on all the connectors and their locations but here's the basics, I got the info from labels on the back of the amp PCB.

Pioneer GM-8066ZT
Toyota part number 86280-33080
marked 86100-33010
Front: 4ohms
Rear: 4ohms
Subwoofer: 2ohms


Grey bundle #1 audio inputs (thicker outer insulation)
ACC - red (don't know what this does)
ACC - black (don't know what this does)
white - amp positive (trigger, turns amp on)

mute - brown
FL input - blue
RL input - yellow
RR input - green

Grey bundle #2 audio inputs (thinner outer insulation)
FR input - black
white - signal ground
red - beep

Speakers
FL(+) pink
FL(-) purple

FR(+) green
FR(-) blue

RL(+) black
RL(-) yellow

RR(+) red
RR(-) white

woofer(+) light green/black
woofer(-) light green/red

Power & ground
brown - ground (heavy gauge)
blue/yellow - battery positive (heavy gauge)
grey - ACC (this doesn't seem to do anything)

The white wire in grey bundle #1 (thicker) turns on the amp this would go to the antenna or power trigger of a head unit. The amplifier has no dedicated subwoofer input so set your head unit to full range speakers. Here's the amp section from the wiring diagram it gives more detail on some of the wires.

The amp is behind the glove box.

Thanks for posting that up. Was there any indication of power output on the amp?

I didn't see any I'd say it's around 20 watts/channel nominal 40 watts peak.
