I am looking at an Autometer air/fuel ratio guage #7575. I really have no idea how to hook this up to my 86. I want to make sure i'm not running too lean or rich. Anyone know how to hook one up?

you have to put a bung in the exhaust, like a 02 sensor hole.

Aside the lights effect, that gauge will not provide you with the info you may be looking for. It uses the narrowband O2 signal (which is a "switching" type of signal) and it will not tell you the actual A/F lambda value. If you still want to pursue its use though, check the installations instructions at http://www.autometer.com/productPDF/0837L.pdf

A better and more economic alternative is to use the EEC-IV and check how it's working, run a set of DIY KOEO/KOER/Cylinder Balance Self-Test and check if you have any rich/lean failure codes stored.

x2 on the narrowband only being good for the pretty lights. Better to look into a wideband.
