ok i bought a defi d-gauge air/fuel gauge. WHy you ask its cheap until i can get a wideband. but none the less. What is the easiest safest way to install this gauge. Can i splice into ecu o2 wire? if so where is it!!!!

Offer some suggestion on what i should do.


thanks

It's cheap because it's totally useless. It's is pretty much just a prety looking gauge.THat's it. It does not do anything at all. It's a narowband gauge so the readings are not even close to being correct.

But to make the pretty looking gauge move around...Tap into your O2 sensor wires.

 

tap the wire on the o2 as mentioned, it's between the firewall and the upper intake manifold area

 

does anyone hav a pic / wiring diagram on this as i am doing the same thing
