Boost gauge wiring diagram...

I found this on another thread that to power up the boost gauge,
these are the wires that I can use...

a. Continuous 12V Power(+) Was connected to the Light in the Glove Box which is Continuous 12V(+).
b. Ignition (+) Was connected to cigarette lighter Power (+)
c. Illumination (+) - Was connected to cigarette lighter Illumination(+)
d. Ground (-) Was connected to cigarette lighter Ground (-)

The question I have is, how do you know which wire is which?
Sorry im a noob but just hoping someone can confirm which is which...

Wire Diagram or color code anybody? Thanks

I hope this thread can help somebody else in the future that may be looking
for this information

Use a multimeter or a test light and find out.. takes less than 10 seconds to figure it out.
