I need the ECM pin layout for a 1998 C3500 2wd 7.4L OR tell me where I can find it.

Thanks

Here'* the main shot.

If you goto alldata.com, you can get a one month subscription for $20 and get all the schematics you need/download. Plus how-to'*, specs etc. It would take a couple hours to peruse all the schematics then download them. Well worth it.
