Most excellent! I just had my mechanic install one this week :
Vacuum Line Connection :
Cheapy JC-Whitney Gauge
It's on a cheezy Glow-Shift Gauge Pod, and then zip-tied to the dashboard cover.
At idle or in steady-state 5th, it reads a steady
10 In Hg. Is that correct? What should it be? Also, my cheapy gauge doesn't go negative like your Sunpro. I don't really know how to use it for shifting. I mostly got it to watch for engine problems.
