Replacing Premium Stereo w/EQ need schematic

I am in the process of replacing my premium sound w/EQ. I've poured through all the different posts I could find on the subject. What I have done so far.

1. Removed the factory radio, eq, and amp.
2. Purchased an adaptor kit.
3. Found the 2nd non-premium (speakes)black wiring plug that is tucked up behind the radio near the glove box.

Wired the adaptor to the aftermarket deck. The adaptor had one orange wire that wasn't even called out in it's directions. (sigh)

The speaker portion of the adaptor (black plug)and the factory harness match up fine.

The power side (grey) doesn't even come close.
The factory harness has 5 wires, the adaptor has 8.

Using a test lamp I identified the factory constant power, switched power, and illumination wire. That left me with two unidentified wires in the grey plug that never showed power under any condition.

I redid the pins in the adaptor harness to match up the two powers and assumed that one of the wires in the factory harness was a ground but I am not positive.

So, does anyone know the function for each of those 5 wires in the grey factory plug.

I only need constant power, switched power, and ground.

Thanks in advance,

Sorted it out myself....

System is now installed as are the gauges.

Now to get the sending units hooked up on the gauges.
