I show:

D14 White and D22 Grn/Wht to be the sensor output. This will typically be a 0-1 volt DC signal, but it moves around a lot. The ECU tries to stabilize it at .5 volts. If the voltage is low, the ECU adds fuel.

Also, A6 Org/Wht and A25 Yel/Blk drives the 02 heater element.

there is no way you are this helpless. Look at the picture on technet. It shows you EXACTLY which connector you need to be looking at.

the answer is yes.

your wasting time and money on this gauge anyway. It doesnt do anything.

the reason why i am having so much trouble is bec i wire into d14 on that connector and it didnt do anything. and i know it was the right wire so chill out dude im just trying to get this gauge working. okay so that is the right connecter correct. what color is the wire? red and white right? bec thats the color on d14.

My manual shows it to be the 5th wire from the bottom (and on your side of the ECU) of the connector you are pointing to and that it is solid white.

In looking at the manual there is a red/white wire on D19, which appears to be on the opposite side of the connector and the second wire from the bottom.
