The APP0111 and the APP8PIO for pioneer.

Micjaiy used the APP0111 and the APP8CLA earlier in the week to help me install my HU and it saved alot of time and trouble.

You'll still need to earth one of the wires which means soldering and that means disconnecting the negative terminal on your car battery so you don't blow a fuse.

Dude why dont you go the Dick smiths and pick up a 12V illumination pen ( $10 ) and a 6 or 9V battery. When the pens finds 12V it will light up. :D All colours I mention are for the Pioneer harness.

With no key only one wire will light up, 12V constant ( Yellow )
Turn key to Acc, another one will light up, Acc ( Red )
Turn your lights on, different on again, illumination ( Orange? )
Use the provided grounding cord and find your own earth ( Black )

Speakers are easy. Test two wires and listen for a popping noise. It will even show you which is poitive and which negative. After doing a few I can tell you that the speaker cables are located on the sides on the harness with the fronts on one side and the rears on the other.
