wifey just brought me a air fuel gauge, need pics of which wire off of the ecu i need to tap in any help is appreciated

 

look in the stickies for a FSM and look in the wiring diagrams, or even in a haynes manual

 

hope you're planning to use it just for looks and that you're not planning to tune with that thing......

 

I searched for "how to install air fuel gauge" and this thread was about 1/4 way down the page:

Also, pay no attention to those that say the gauge is "just for looks". True, you won't do much tuning with it, but it's far from usless. The reasons have been covered here many times.

 

Sure there are uses, and I guess it's good that it's free.....I dunno, I'm just spoiled on widebands.

EDIT: Shouldn't you be at a Boxing Day sale somewhere?

 

IF you can read this, then scroll down to the bottom of this page and you'll see several theads that relate to 02 gauges. You might read one or two.
