that car doesnt have a factory harness listed because it doesn't need one..
wiring is:
speakers ( these are on 4 pin plugs):
gry set - rt rear
green set - lt rear
orange set - rt frt
red set - lt frt
theres a 3 pin plug that has power and lights on it.
wht/blk - +12v
wht - +12 via key.
red/yel - lights
if the car doesnt have rear speakers the cables are located behind the panel that covers the boot latch.
that should get you started.
