Can anybody explain to me why it is you can not (at least the =
aftermarket manufacturers prefer that you not) weld on a vehicle while =
the ECU is connected (electrically) to the vehicle?  It seems that =
muffler shops weld on vehicles with factory ecu's all day long without =
trouble, however I have heard many horror stories of damaged aftermarket =
ECU's and ignition boxes when somebody neglected to disconnect the =
harnesses?  I have never really been given a good answer, I just follow =
the rules and hope to avoid disaster...

-thanks
-Chris
