Maybe another place to check is. The cab grounds, specifically the one that grounds the cab to the engine block. On my 389 it goes to a lug near the starter.. I had a lot of weird glitches with the dash, a lot of weird symptoms that made it seem like computer was going our. Long story short after many hours of frustration, @Goodysnap pointed me in the direction of the cab grounds and that's wat it ended up being. Might. Be a good place ti look if u keep having problems in the future

I removed my cab ground terminals and cleaned them all up last year. They had that white salty looking corrosion thing going on. Didn’t look too bad until I removed the nut to disconnect the ground wires.
