I have to weld two brackets on to my roll cage for my seat bracket.
Should I remove the MSD box completely from the car, or just disconnect the wires and leave it mounted?
I don't want to fry the box, and I've heard welding can mess them up.

At work we have to unhook the battery before we weld anything.We have fried ecm's like that.Removing it completely is probably cheap insurance.Really not that much haggle.

i have always just pulled the battery for any welding on mine, and kept the ground as close to my welding as possible. i9 guess ive been lucky. i know they do get fried easily by battery chargers, and jumpstarts.
