Ok, Ive tested everything, Im pulling the PCM… I got all screws loose…
how in the hell does this thing come out of the hole?
I’ve googled, many responses say, just pull it out… that can’t be true… this s.o.b won’t pull out.

Lastly, now that I'm convinced the PCM is cooked. (Nearly every pin once exposed had some sort of corrosion on it).
Have any recommendations for a reputable place to get a new one online?

It does not just pull out...
I have used a broom stick to pry down on the inner fender a bit to get some clearance.

Yeah, I watched that video...and many others. If you notice, they all cut the video until they get it most of the way out...
But what you're saying is...It does pull out (there are no additional clips, screws, etc)....it's just an S.O.B. to get out.

Ok, I'm at my wit's end. Other than taking a plasma cutter to it, I have no idea how to get it out of the hole.
Are we sure there aren't any clips somewhere? There are 2 small clip-looking things on the sides, but nobody ever mentions them.
1. I've run PB Blaster into the hole.
2. I've removed the tire and the entire wheel well.
3. I bought a bolt and threaded it into the PCM to use for leverage...The bolt stripped all the way out, and disconnected...The PCM never budged.
I've been yanking on this thing in one way or another for over 2 hours. It doesn't move.

I wonder if I can get at it from inside the truck? Maybe take off the driver's side kick panel and properly beat the living hell out of it with a large hammer until it either shatters into 50 pieces or pops out the other side?

Glad you got it out. Nice video. Overall the condition inside is not bad from afar, but with all that corrosion on the outside you can bet there is damage inside as well as the pins. Check the cowl drains to make sure they are clear to allow moisture to drain out. Look closely at the seams to see if you have a leak getting into the cab. I think the hood/cowl seal extends over the PCM are too. Something else to look at.
