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.

I have welded on my rockcrawler probably hundreds of times without ever undoing batts or worrying about the computer. Still runs great... rolls over alot...hmmm maybe that's the problem :brightidea: :flipa:
