This is correct if you are NOT running it through the PCM (with a carb, for example), but, if you are going EFI, just let the PCM control if and nothing has to be done with it. Even if your truck has a GEN light, which I just assumed it had a voltmeter (we all know about ass-uming ), I wouldn't use it.

As for a mechanical oil pressure gauge, check my build threads, at least one of them shows how to easily fix that with a drill and a tap. Super simple.
