Hi guys I am going to be doing some welding on my truck in the next couple of weeks and I was wondering if I needed to disconnect anythng so I dont fry it, possibly PCM. Just asking.

You should unhook the batteries. The ecm doens't like power spikes. You also should weld on the frame as it's heat treated if you can avoid it.
