My question regards which wire out of the o2 sensor to splice into. I lost my directions and have no clue which wire to run it to. Once i figure it out I will take a few pics so everyone can see what it looks like. thanks

 

I'd suggest installing a separate bung and separate O2 sensor for the A/F ratio meter. Given the slight voltage changes of most sensors, I could see how "splicing" into the factory one might throw off the signal to the computer.

There must be a name on the gauge. I'd recommend contacting the manufacturer and getting their instructions. You don't want to make a mistake that might damage the computer (even the sensors can cost $50-$80) and have to replace it.

Let us know what you find out.

 

I would definitely go with a new bung and wire set up.

 

I've never really gotten the concept for them. Both of my kids put one in their cars, and they look cool with the light bars bouncing around, but nobody's been able to tell me what the use for it is since you can't do anything about mixture anyway.

 

If your running extremely lean for a long time you can fry a piston. As in burn a hole through it or something else to render it useless. I did this to my jetski when it ran lean on the #1 cylinder (a story for another day). If you notice it running lean, you can let off the gas. But, it is mostly for looks on todays computer controlled vehicles as you said. The computer will try to keep an ideal stoichemetric 14.7/1 air/fuel ratio.

 

You can't use the factory O2 sensor. Trust me I tried. It does not work. You have to have a new bung installed
Then I just used a single wire O2 sensor and now it works awesome.
I used Autometer Gauges for my Air/Fuel, Tranny Temp, and Oil temp. Work Awesome. I also used the Three gauge pod that replaces
the cubby hole in the center of the dash. I'll have to post pictures.

 

Dr. Meow,

Sounds sweet. Please post some pics as I am interested in the tranny and oil temp. I guess I could fill in the third spot with an A/F if I needed to. By the way, what are your normal temps.

 

Here's a couple pics

sorry about the blurryness!!

 

That's a cool setup. How did you wire everything and what are the normal temps that the tranny and motor run?
