Bi-color EVO gauges
 

I use vacuum/pressure bi-color (red/blue) EVO gauge for my Z32 and I'd like to share one idea. Gauge can be red or blue color, depends on wire connection. I added vacuum/pressure switch to the schematic. Switch has been pulled from old furnace with inducer motor(or you can buy new switch from HVAC supplier). Now I have blue color at vacuum and red color at pressure. Switch is very sensitive, you can see how "0" goes from blue to red.

nice
 

very cool and inventive Idea :armata_PDT_37:

That is pretty neat. Got a video of it in action?

Coooool
