Noob question; Installing intellitronix digital gauge, (tw: LOTS OF DUMB QUESTIONS)

I think your making this more complicated than it is, think of it as just replacing your existing gauges with another one. The hot or trigger wire from the new gauge can be plugged directly into original harness plug that hooked to the back of the OEM gauges panel, you just need to follow the hot or trigger on the OEM guage panel circuit board to each gauge to figure out which one to use for your new gauge.
