I am looking to get an air/fuel ratio meter installed on my 1994 325 ic, and was wondering were I might find the oxygen sensor signal wire. Can anyone help me out.[???1] [???1]

I am not sure how many wires a BMW has for their oxygen sensors. I would think they'd be 4 wire sensors. You should get the pin out of the plug and splice into the wire that gives the computer the signal. While you're at it you might want to change the sensor for accurate reads.

Not to be a total square, but what's the DME?
Manuel what part of Houston are you from, that is my hometown and will be there for the wonderful Christmas weather. Are there any good events going on?
