hey i am installing an air/fuel gauge(autometer). and i hooked the purple wire to the white wire on the very lowest connector on a pr3. is this right i thought you were supposed to hook it up on the o2 sensor wire on the ecu. but all the gauge does is sit at 1 led all the way on the rich side. does anyone know what is wrong

This may help!

 

now i have hookes it up to both c16 and c8 and they both give me the same led lit up.

yeah, you have to drive it a little to warm it up... a search should have cleared up this problem.

 

on me for not searching enough!

 

grrr now it is not working.... when i put on my running lights it moves to lean then if i put my headlights on it goes more lean and if i use my turn signal it will go lean when the arrow on the cluster comes on and i have the power for the gauge hooked up to the radio power and then i have the o2 sensor hooked up at the #1 o2 c16 on my pr3 ecu why isw it doing this?

where are you grounding it?

 

i am using the radio ground....... is this an ok spot to ground?
i will take a few pics of what it does when i come home for school....arrgghhh schooool.......

 

Yeah, make sure you let car warm up and drive it around. It should work.

Now for your second problem: You are having some major interference problem, I would suggest taking that ground out and connect it to you battery ground. That's what I did and it works great. No interference at all.

 

I always ran the 02 wire from the 02 directly about 6''s back. Run a dedicated wire for it then a good ground. Now when you turn on radio, headlights, or anything electrical it will move it a little leaner because there LED lights and they also run off of 12volts and its extra drains on your electrical. When setting A/F make sure nothing is on and that will be as true as a narrow band 02 will get

 

so for all of you the gauge will read leaner if you cut on any electical stuff?

 

yes because its getting lesser voltage....same way you radio or headlights will dim if you have a large system with a large amp when ever the bass hits
