newbie help

Hello All,

I have downloaded the software and have my cables all built.
I'am wondering what information I need to get off the vehicle to
properly setup the def files. I will be using the system with an
1988 S10 Blazer 4.3l and an 1993 S10 Blazer 4.3.

First step is to figure out what ECM you have. Pull it out and look for the part number.
