Hi Guys,


I have an Air/Fuel Gage and I want to install it to the GK. Now, I know that it doesn't really pull correct numbers and is just a light show, but I still want to have it on my dash.


My problem is, I have 3 wires and I'm bad at electrical lol.
black of course is ground
white they said is O2 sensor
and Purple for ignition switch


Before I had it on my EK, so there, it's pretty spot on.


On the GK I have push button, I need help on where is the easiest wiring diagram I can get to get this project of mine done?


all the help is much appreciated.
Thank you

 

before you tackle the wring colors, I suggest using a volt meter to assure yourself the color of the power wire so you don't fry some wires or blow a fuse. The convention for house wiring is black is HOT, green GROUND, and white RETURN.

 

Hello,
The easiest way if you can't find the wiring diagram is to buy this:
https://www.amazon.com/dp/B00C9QT8E2...I2E0DSBQAY6493

Then plug in the fuses (2 fuses, one for current line that you tap and one is for the supply line that goes to your A/F ratio gauge).

and then test it on any of the empty slot or any slot on the fuse box that turn on whenever you turn on the ignition/engine

by the way,
I am currently using the AEM UEGO A/F ratio gauge and the number it show is VERY Accurate and if you tune your car, it is not just a light show but a really vital indicator.

 

is ur car running forced induction? not sure da reason for a/f gauge on a NA stock or fairly stock car.... in fact I own two turbo charged cars and even on those cars i don't run a/f gauges. I have da capability to log a/f ratios though...
