Just got my gauges late yesterday.Got a set of isspro from pdr.Where did most of u guys hang, attach the little boxes that came with the pyro gauge??

 

I put mine behind the panel below the steering wheel. The panel has 3 screws and pulls off no problem. Behind the panel there is a thin steel support member, nice flat spot to drill one hole and mount your box. Just make sure that you point the wire plug towards the firewall, makes it easier to run your wires. Good luck.

edit: Shoot never mind... I just saw you have a 1st gen.
