You must have yokals working on your car. Welding uses high voltages... Anyone who welds on a car without disconnecting the battery, should have their sack welded in between two plates of 1/4" thick steel stock, then smacked with a hammer.

FYI, if you put an A9L computer on an harness from an automatic, thats the exact thing that happens. Car will not advance timing and will eventually fail completely.
If you dont know how to tell if the harness is form an auto or 5 speed, it can be told from the O2 sensor plug.
A guy named Dan laid out an awesome pictuoral on a Cleveland based Mustang site.
