90 toyota camry stereo wiring

I have a 1990 Toyota Camry, I just took out the stock factory stereo and bought a Pioneer stereo for it. MY question is how in the world do you install it, what wires specifically go to what wires that the old factory radio was hooked up to?

For example, on the new stereo I bought the yellow wire in it is for the battery, because it says so in the manual and the red wire is for the ACC(accesory) and black is for the ground, I tired connecting the yellow wire to the yellow/blue wire in the car to get some power to the stereo and the red wire to the gray wire to get the ignition or ACC to work on it, but nothing happens, I connected wire after wire but the stereo does not flip on.

Does anyone have any suggestions, or know where I can get a very accurate wiring diagram for the radio?

Thanks for any Help.

The Illumination wire, the green one, connects to which to what wire on the new stereo?...I tried every wire, now, I connected all the Yellow, red and black wires to see if it would power on, but it did not,(maybe I must connect the Illumination and the speaker wires to actually see the stereo light up and hear it?) but I think something other is wrong here, and I already cut all the factort wires and stripped them, yeah, I know I thought too much adhead of time on that, shouldn't of though.

But i'll keep trying it...might aswell.

Thank you much though.

Where might I find the fuses in the car?
