Thanks for the info.  Issue is not the light coming, it's seems it doesn't
come on at startup sometimes for the check. That drives me crazy.

Engine pressure is fine, I have no doubt about that really (well mostly,
hence wanting a gauge) this is for peace of mind. It only has 2k miles
since a meticulous install and quite a few component upgrades including the
30mm oil pump. Also, I live in WNC so no crazy grades, elevation or long
hauls for camping - it's all in my backyard.

I figured if diving into that ssue I should go ahead and work on a better
solution.

What I do like about Ken's kit is it looks pretty easy to install, gauge is
top notch and of course reputation for his work.

 What I am concerned about is adding complexity to an area not associated
with measurement.  That is, the other between rockers takes the stock
location and adds to it. That makes sense to keep packaged like that to me,
regardless of the effort.

I do wonder in terms of location is one or the other a better location to
gauge the entire engine pressure? Meaning rocker vs filter location? Or
better yet, is one of the locations a known point of low pressure?
Also, is 10psi pretty standard for the low end on a gauge?

Thanks y'all! Do appreciate the help!
