Oxygen sensor

[HUM GOOD]

Good looking out Ira - I'm hookin up a air ratio autometer gauge, I got it working. I taped into the sensor above the cat(the blue wire). I have a scanner so I was able to check the readings on the wire. I have done many mods to the rig in the last 2 years. I have 75,000 miles on it and want to keep constant monitoring on certain things. I have played with the tuning plenti times also and I don't really trust the idiot lights in the rig all that much. Besides this gauge particularly looks cool on the dash.
Thanks for the help.

Does your man Fred have a 4 wheel drive dyno I can toss this baby on. I found a guy in ridgefield nj.....wants $125 and hour for machine time. I thought that wasn't bad.
