Silverado gauges I have a 2005 Silverado with a 2014 ls3 out of a Camaro in it.
I'm running a psi stand alone harness with it. My question is how can I use my stock Silverado gauges with the setup I'm using. I've been researching for weeks and cant find anything

all inrealy want is my tack, oil pressure and coolant temp to work
No difference from ls3 to psi, I said should have used your truck harness, then everything would have worked BUT would have required a lingenfelter conversion box for 58x-24x. Your probably going to have to piggy back the stock harness and pcm with you standalone harness and run 2 coolant temp sensors since you cant split a thermister signal if you want the stock gauges to work.

If you would have the original engine harness and pcm then there wouldn't need to be a solution, it would all work. Or you can piggy back your old harness and pcm for gauges or try to wire each gauge one by one (piggy back old harness be easier IMO. No one is selling a solution because the solutions is already there.

If you run an E67 ECU and harness with the later trailblazer operating system it will run the LS3 and communicate with the Stock Silverado cluster.
