Does someone have a diagram of the wire pinout for the ECU?

I'm looking to find the wire I need to splice into the get the 0-5v signal from the O2 sensor, to hook up an A/F gauge. I'm planning to just splic into the wire comming straight off the ECU.

Any help would be appriciated,

btw - if your looking to hook up a narrowband a/f gauge dont even bother. Its going to be useless, that is unless you like light shows..

I got the gauge for free

So yes its for the light show. I will have the wideband setup in about 3-4 months when I get the standalone in and tuned. I will take the narrowband out completely when that happens as you don't need an O2 sensor when running standalone.

Thanks for the diagram NJSupraA70.

I just did this too (and yes, I like light shows !). It is pin #6 on the center ECU plug, a white wire (that's for 89+ btw).

I have a 90. Question is that diagram up top shows #6 in the center is THA which is air temp sensor. I thought it would be the #3 from the center plug on the diagram (OX)
