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

Ok so I used the alphabetical index. For fuel gauge it took me to this page and it says "CI 10" similar to what I posted above. So does this imply that the wire is "G4 18 DBL" meaning its "A" on the printed circuit connector? Mine is blue with white stripe...

WTF :BangHead::BangHead::BangHead:

What I see here, and double check this, is, the two orange up at left are your dimmer controlled dash lights

Violet is temp sender
Dark blue is ignition "run"
Blue/ white is fuel gauge
Grey is oil sender

That last diagram you posted you sure it is A body, and not E/J/ etc?

Easiest way I know to double check is disconnect temp and oil, check at cluster connector, should both be open, then ground one or other and that one obviously should be grounded.

One thing you can do when testing to "not" blow stuff up is to put a big wattage lamp in series with battery ground. This will allow you to power low power circuits and test them, and if you short something, it will just light up the series lamp. Use a headlamp or an old stop/ tail with both wires on the socket wired together, and then ground the shell.
