Making this gauge work (electrical knowledge help required!)
I'm looking to get a new oil pressure gauge, and came upon this in another thread (Thanks JasonY):
Automobile Multimeter for EGT, Boost, Amber [SYL-1813A] - $53.50 : auberins.com, Temperature control solutions for home and industry
I've fallen in love with it and now I need to make it work. It says
Quote:
For water/oil pressure measurement, the meter can work with either old style resistive pressure sensor or the modern style pressure transducer with linear voltage output. The meter offers a regulated 5V DC output for the power supply of the pressure transducer.
So assuming our cars use either of these outputs (I have no idea, can they?) all I need is to wire the gauge in with a power, ground, and signal wire. If I use the stock sending unit - which is my hope - which color wire is ground, power, and which is source?
If our stock sender won't work, I had planned on using one of these senders and harness with an adapter, since it is so small in size.

Could I then feed three wires from that (power, source, and ground) into the unit and make it work?
tl;dr how do I make this beautiful piece of machinery work
