Does anyone have a diagram that shows clearly which pin on the chip is the +5V pin?
I need to connect the chip outside of the programming board and I can't find which pin is the +5V pin on the chip itself.

I think i got it but i just need to know which pins I provide the arduino power to? IE the 9V battery to run everything.

Assuming no further information from you, I would tell you that the manufacture's datasheet for 'the chip' is where you get the answer to your question.

sorry. It's just running two servos.
I have the 5v power to the servos connected to pin 7, ground to pin 8, and their signals wires to A0 and A1
It will be powered by a 9v battery, so those are the only connections I have left to make.
To which pin would 9V go to, to power the board and motors?
But what is "the" chip?.....

You need to back up and tell us what you are working with, a standard arduino board? What model? pin 7 and pin 8 where, on what? Pins 7 and 8 are digital pins on an arduino board, not a way to power servos.
And finally a small 9 volt battery will not have enough current to power an arduino board and two servos.

Arduino Uno R3. I don't want to use the entire arduino board, but just have the arduino chip on a small PCB.
I used pin 7 and 8 based on a diagram I found for the AtMega128, the adafruit labels I bought also show pin 7 and 8 as being VCC and GND....so I'm a little confused.
Anyway, whether or not it will run from a 9V battery is not my problem (looooong story) I just need to know which pins to use.
Looking at the arduino board, I'm using +5V, GND, A0 and A1, as well as whatever 2 pins are used to power the arduino. I just don't know which physical pins on the 28 pin arduino chip I need to use.
I bought also show pin 7 and 8 as being VCC and GND.
What pins are you talking about? Pin 7 & 8 are the power and ground on the ATmega chip not the arduino board.
based on a diagram I found
A link would help.
Is this the information you are looking for?
If you are using A0 & A1 be sure to connect +5 to AVCC as well as Vcc.
