Hi all.
Havent seen a thread like this yet so I thought I'd post my findings. This project is far from complete and I havent even decided how I'm going to finish it off. Might go with micro amp and small sub or go all out with 2 full size amps and larger sub.
I digress - here is the meat and potatoes of the thread:
The oem amp harness uses a standard toyota HU harness (ie Metra 70-1761) however, the wires are far from standard so I took some time, repinned the harness and am now trying to decide how to use it.

The newly repinned harness
For those that dont know how to remove the pins simply take a large sewing needle and lift the little white plastic tab while pulling out the wire. Fair warning: some of those buggers are snug, I had to use 2 hands on the harness and my teeth to pull the wire out.
Im hoping to maybe use

PIN Map:
Wire colours:
Red = Battery + (always on) [PIN 1]
Black = Ground [PIN 2]
White = LF Speaker amplified out (black line means -) [PIN 1 and 5]
Grey = RF Speaker amplified out (black line means -) [ PIN 2 and 6]
Blue = remote turn on [PIN 8]
Green = Left speaker signal input from HU [PIN 3 and 9]
Purple = Right Speaker signal in from HU [PIN 4 and 10]
