Need to hookup up an autometer air fuel gauge temporarily until I get my FJO unit.

Where can I find the o2 signal inside the car?

I don't want to go through the firewall for a temporary hookup.

You need to unbolt the ECU, turn the back towards you to see the connectors. It is the 3rd wire from the left, 2nd row up from the bottom - yellow with black strip like all of them! I removed the connector to get to it better. Also will have to ground it to a wire there of chassis.

The diagram is in the manual if you want to see the main 02 wire there to be comfortable.

Honestly, just hook a volmeter if you have one shoot for .900mv on 93 octane & .850 on race gas - those gauges are too much of a ballpark reading.

I am getting a Jumptronix gauge - nothing but a voltmeter that will fit in a gauge pod for $80. I used one for 5 years on my Talon.

Or do you want my Greddy A/F gauge - comes with o2 sensor, etc. Sells new for $287, sell it for $140.
