Many folks say you need do nothing, I didn't for 35 years until I burned up a $550 Toyota PU computer while welding on the tailgate. You can take your chances or at least disconnect the batteries. Even better also connect your truck to a real earth ground. Here's more info https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=17443

thanks for that link, it looks like a battery disconection is in order as well as unhook the computer for extra safety. thanks ET

Also make sure you put the ground close to the place you are welding.



Don't put the ground at one end of the truck and weld on the other. That will smoke boards even with the batteries unhooked, because they are still grounded. We have to weld on compressor packages with PLC panels and computer controlled ignition systems, sometimes the guys smoke-em even when they are unhooked (not moving their ground leads).
