    Resource for wiring diagrams: '11 Silverado 5.3L (LC9)

    Does anyone have a wiring diagram for a 2011 Silverado with the LC9 5.3L? Or even just a good pin-out diagram for the E38.

    Thanks in advance and my apologies if this is posted elsewhere (I did a search but couldn't find it).

    For a conversion project, the involved schematics would be 20 plus pages. The E38 pinouts are another 2 pages - and not really that much help without the schematics for reference.

    Electronic manuals are available from Alldata, ACDelco, and other sources. Printed manuals are available from Helm.

    Here's a link to the 07-08 E38 Pinout.

    Buy a 3-day subscription to GMSi for 20 bucks and you'll have access to complete service information, incl. wiring. GMSi is the same on-line service info. dealers use. Go to the ACD TDS web site for more info.

    3-day sub, and install this: https://github.com/ckaiser/Lightscreen/releases

    You can configure it for an easy key combination that saves a screenshot of only the browser window, it saves files automatically to a default folder with no interaction required. Hit the keys and you've got an image. Open the next diagram, hit keys. Repeat until you've gone through all the relevant pages, then you've got the images saved forever to print off as many times as you need.
