The only thing I don't like about the OBD2 stuff is.

Doesn't hang down lower and is real easy to hit when getting in and out of the truck.

(I've never had one I'm really just asking if anybody that has ran their truck that way.)

Well lucky for RJM27 because he has a 2008 and that's why I said it.

Anything NNBS runs can-bus. Anything E67 or E38+.

The OBS plug does not get in the way.

It's only sticks out maybe 1in further than stock and your legs will not curl under the dash and hit it. Ran my last truck for over a year and never once touch it and half time forget I even had it hooked up.

So will that one display boost on the gauge too since it can read it through the OBD2? on a newer truck. Mine is 2014

Not that gauge. That is only an AFR/Lambda wideband gauge. I am not sure if they make a wideband/boost gauge with OBD2 support. Haven't looked at their site to see what new ones they offer with OBD2.

So what about Wiring for an Auto Meter gauge on a NBS I don't have the little data logger in the picture I was wanting to run it to the factory PCM EGR pins this is what I have heard would work. Just not sure what wires go to what pins. 2004 Silverado pcm I have already wired
White to Headlight switch to power Gauge lights.
Red to switched 12V
Blacks to good chassis Ground

Need to know what pins for the Blue and the Brown wires.

If blue is 0-5v analog output it goes to the pin 55 egr location.

Does the black (-) output need to be connected to a quality ground source? Or left hanging unused?

Apologies on reviving an of dead thread!

Using a good ground is always best

Ground it out it is. (Edit: signal output negative is what I'm talking about. )

Thanks
