Have you opened up the computer to see exactly what was burnt? If it's the same place every time that would suggest a wiring short which you would be wise to track down.

The EEC plug should have a rubber gasket around it and the area where the wires enter should also have a gasket.

Yes the plug has a gasket on the in side of the plug but not on the outside also if I open the computer it will void the warranty on it

Do you still have the original computer? If so take that one apart.

How do you know it's blown anyway? Have you pulled codes and if so what do you get?

When you installed the "new" computer did your reader work? It's not uncommon to have corroded pins on the data link connector.

Do you recall what the code was by number and what test it was displayed in?

Depending on when a code is displayed it can have very different definitions. And to be perfectly honest I do not know what code equates to "a short".
