I take it that a PCM or CTM is some type of computer for the guages?

 

While I was taking dash apart, I pulled my radio and saw that the fuse was blown on the back. It also had that horrible burnt electrical smell. I went over to the antenna and saw the cable wasn't connected and the end had been burnt. The antenna cable just so happens runs in through the engine compartment, butting up next to the PCM. Im figuring the lightning entered my truck through the antenna. I'm going to get a flashed PCM and hoping it will solve the problem.

 

That sounds like a pretty likely scenario.......

PCM is Powertrain Control Module. (the one on the firewall, right by the antenna wire....)

CTM is central timer module. Basically, it acts as a network hub, distributing information to whatever systems need it.
