It's difficult to see, but looking closely with a flashlight and a magnifier, it does look like that alternator fuse is blown.
I guess I could try what's shown in the video.
If that fuse is blown, would it account for the vehicle not coming out of park? The alternator is in the circuit path for what?

It's the main path through the entire electrical circuit.
I won't tell you to drill out the top of the fuse and screw a fitting bolt down in it...

Are these supposed to be user replaceable? I can see that the ABS fuse is blown. I tried pulling on it but naturally want to be careful. Do I just need to pull harder?
If I can change out the alternator fuse myself, and get this thing going again, that would be great. In my younger days, I did a bit of mechanic work on my cars, but never would I say I really knew what I was doing.

Some of these modern fuses are held in pretty tight by their connectors to ensure they don't vibrate loose and resist corrosion through a light connection.
Pull harder, you'll know if it's bolted in from the sides. I'm wagering it's not.
Mars and I just finished up a full engine swap on a 2003 Nissan Frontier, electronics and all. That was tough work... I'm still sore.

Thanks to all of you who've helped. Really appreciate it very much.
SC, you mentioned employees who might be able to address this. If you've got someone who could pay a visit instead of my having to have it towed to be sexually assaulted by a garage, I'd be delighted to pay for that privilege, even if it takes a while to get to it.

My quess is the starter relay may have burned up. You might be able to swap the horn relay with the starter relay if they are same.

If so, it would be in addition to the alternator fuse, because that fuse is blown for sure.
The fuse he mentioned in the passenger compartment- I checked it and it's OK. AM1 and AM2 also appear to be OK.

I wish I was closer.
It’s a bit fidely but not as complex as a Ruger MKII pistol.

A vehicle with a dead battery won't come out of park so a break in the circuit could produce that result. There will be a shift lock override button somewhere near the shifter that will allow you to shift without power, usually so you can get into neutral to push.

Hell, I didn't even know about this and I've owned this truck for 17 years
I looked at your relay part number and you don't have one to swap around.

I guess I should assume that this relay is burnt and buy one along with the alternator fuse and the ABS fuse.
What's that relay part number?
I found on Amazon what I thought was the correct alternator fuse. 120 amp, looks like the right part but the Amazon parts guide say that it won't fit.
I suppose my local Auto-Zone can sort out the part number for me.

Set the meter to ohms. You should not get a reading on the meter with the leads apart, but should get a reading (zero) with them touching. So, pop out a fuse, since it is hard to tell if they are blown or not, and put the leads on the back of the fuse where the 2 metal prongs are. If you get a reading (0, 1, whatever), your fuse is not blown. No reading, and it is.
As far as getting them out, yep, sometimes they are stuck in there. Try using some needle nose pliers, if they are closely packed in, or just a regular pair of pliers.
Might help. Good luck, I hate tracking down electrical gremlins.
yeah, you can read ohms, or if you’re lazy like me you can check for continuity. Touch the two leads together and get a beep, separate them and all is quiet. As you touch opposite blades on the fuses (or the reverse end if you’re lazy and don’t bother pulling them) you’ll get tone if they’re good, silence if they’re blown.

I don't have one of those gadgets but perhaps I should get one.
Do any of you have a recommendation for one that's functional but not extravagantly priced?

Apparently, there are clips around the fuse box housing that will release the fuse block allowing you to lift it up high enough to remove the bolts for the alternator fuse:
I'm guessing the one nut left of the fuse (when standing in front of the truck) would also have to be removed.

Toyota starter relay part #28300-0A011 I think it's made by denso. Pricey from Toyota of course.
Hi Para. I have a first gen 2000 Tacoma 2.7L 5 speed. I accidentally reversed the cables when jumping it a couple of years ago and had the same symptoms. I fried the main fusible link fuse and it was bolted in and difficult to change. It looked like this (below). I dont know what year your Tacoma is, but you might Google "how to change fusible link" in whatever year and engine truck you have. I had to remove the fusebox to get to the bolt that was anchoring in the FL main fuse.

The other bolt looks like you can get a ratchet in there.
I don't think I'll have to remove the fusebox altogether. As a matter of fact, I'm not sure why the guy in that video loosened the mounting bolts for it. Maybe I'm missing something.
