What do you need help with? Im in the middle of putting mine in right now.

If its directions you need, Here ya go:

First you need to wire the red wire to a 12volt power supply. This can be found my using a current tester.

Then you need to ground the black wire to the chassis.

Lastly, you need to go to the passenger side and take the kick pannel off. Once you do that uncrew the wiring harness' and find the silver one with 100+ wires on it. Find the wire(it is grey with light blue stripes) in the #60 location and splice the purple wire into it. You will probably need to buy some wire at an auto store. I know my purple wire didnt reach so I had to exted it a little.

What difference does it make?

Because when people think its a stupid idea i guess they feel the need to tell the rest of the world... but nobody really cares

LOL!

I have one it works great. It's not a bs gauge like most ppl think. Yeah, It ain't no wideband, but if you know how to read what it does when it's doing it, it can be very helpful. It's helped me out a few times.

I just finished installing mine about 2 hours ago.

THANKS 2K1GT. My question is how did you conect the red wire(electrical tap, those conectors when you squeeze them slice automatically.What wire did you actually connect it to ??? What did you actualy ground the black wire too(firewall,???). Lastly, did you actually splice into the the ecu, or on the harness going into the ecu. I was told I need to ground myself b4 I touch the ecu. Im very novice at electrical, so your instructions are important. Im alittle nervouse about burning my car to the ground(LOL).
I bought the gauge because my car sounds like it's running rich. I've adjusted lean and i've adjusted rich and I can't seem to get it right. I appreciate you input.

ALmost forgot, my instruction said something about a 5 amp fuse on the red wire. Did you do this, can I but this at Murrys/autozone??

I know this is off topic, but I would recommend a wideband over a narrowband. Try the UEGO, or NGK AFX meter!
