i have a 1997 silverado, 4wd, and i believe my computer got shorted out and went bad, so i called up my local yard and had them look up the computer, they told me that the computer for a 2wd and 4wd is the same, i have a hard time believing that, i know my computer has 5 plugs going into it and i think the 2wd only have 4, (4wd has an extra for transfer case would be my trheory) so i was wondering if someone with a 2wd could take a look and tell me how many plugs go into the computer, thanks in advanced
