Still having a hard time with my gauge. I found this.

Now I don't have the gauge ground and 12v power hook up to the ECU. Ground and 12v power is to the turbo time. And the other wire is to the o2 sensor port 4 on the ECU and nothing. But my scanmaster 3 reads o2, and a/f. Could it be that I have to connect the 12v power, and ground To the ECU? Or it should not matter?

I remember the plug was under the glove box some place(it's been many years). The instructions should be the same, but the DSM ECU is below the stereo and a GVR4 ECU is on the floor by the passenger kick panel right of the glove box..
