So I'm looking for the wiring diagram, and is it up to date with all the small things listed with the speedo, egr, and air conditioning issues? I'm putting a 383 into my 1998 Silverado and this is my last step. Thanks.

You need to PM Lextech with an email address and the year of the truck you are doing the 0411 PCM retrofit on. He is the creator of these retrofit PCM pinout files. All the details have been ironed out.
