Let us know how the pressure gauge works out as well. I used one of Cyberdyne's digital temp gauges to alternately monitor both oil temp & coolant temp on a project about 10 years ago.
It was fundamentally accurate, but they were still evolving the circuitry that time averages the readings seen from the sender & the gauge display update rate. In simple terms, the display would often tend to quickly fidget btwn 2 adjacent numbers.... eg. 195, 196, 196, 195, etc. Not inaccurate - but kinda annoying.
One would hope they've got that well sorted by now.
On the gauge location options, I put 3 gauges in the cubby below the radio. It's reasonably easy to see & looks OK (pics in my album), but was a good deal of fab work & the mechanical gauge tubing feeds really complicate removing the dash bezel.
As another location suggestion, if you're not a smoker, the fold out ashtray might be an easier mounting location to work something into w/o undue fab time. If you're OK w/ the gauges quite a bit below line of sight, that location might offer some easy real estate to re-purpose.
