Now all I have to do is fish a wire out to the sensor and
hook up the gauge.

(just a directory of pictures, I'll do a writeup later)

It didn't go so smoothly. The gauge and tube took a while to
figure out (no hole install) But I had to take the A pillar
plastic off one more time than I should have had to. (didn't get
the wires in properly) and broke the friggin plastic/metal clip
thingy. Well, I'll have to JB weld it back later, but for
now it's fine.

Amazing what you can do with PVC pipe.
