The first thing I would check is the flasher control unit. It's a computer circuit. It may have been damaged by the welding arcs.

I have to ask, with the lenght of a mega cab already how much did you extend it and why? Just curious..
I think your problem is *because* you didn't touch anything electrical. Wires don't like to be stretched.
The MC only comes with a short bed. Some folks love the MC, but just have to have a long bed so they extend the WB and swap out beds.

Man, a MC long bed, that has to be fun navigating around mall parking lots!
