Hey guys! SORRY if this is a total newb question, I promise I searched and searched and searched before I decided to just ask.

I own an 85 Fiero GT that needs pretty much everything on the interior, so I thought I'd be unique and try to install this 145mph Camaro 82-89 speedo I got my hands on through a Camaro buddy of mine. I have the Fiero wiring info but I can't get a pinout on the 82-89 Camaro 145mph cluster. I don't know specifically what year between 82-89 this one came from.... maybe that'd be the first thing I'd want to learn if possible?

I found some pinout schematics on this site but none of them agreed with each other... I am assuming that year to year, plus model to model (motor to motor) there were differences? So if someone has this information, I would worship the ground that you walk on!
