Independent dedicated switched battery line? ECU power line?
Chris
So my electronic boost gauge needs a power source that is ignition-hot...but it has to STAY hot while the engine is cranking (key in "start" position). This is for the auto calibration function of the gauge.
I can't find anything that fits the bill. Hoping someone with more experience can help me out.

Who makes the boost gauge and what does the instructions say?
Also, aren't the interior lights constant power as well?

Whatever powers the ECU, fuel pump, ignition would be hot while cranking and while running.

Ummm...what about that little blue plug (not sure of the correct name for it) on top of the wheel well on the driver's side? The one you connect to when checking timing? Isn't that one hot?

So it looks like the Light Green wire coming from the PCM on connector 3 position N is the signal to the fuel pump relay.
My question is do I tap into this wire for my power source or do I need to go for the Red and Blue (R/L) wire coming out the other side of the relay? I don't have much of a clue how to read these types of diagrams.
