I had some critter get in underneath the engine cover of my '07 ES350 and chew things up, causing misfire of the #2 and 4 cylinders. Can anyone point me to what part I need to order and how easy it is to do? I couldn't find any YouTube videos online for it...they're all about replacing the ignition coil and the spark plug but not the wires.
This appears to be wire harness damage that needs professional repair. There is not any part or wire involved that can be easily removed and replaced. I would find a good independent shop, maybe one with an electrical repair speciality. Or the dealer.
The problem is obvious, but those wires are part of the harness system that connects everything and there is no plug connection at the other end, thus they need to repair the damaged areas. This should not be difficult for a pro to repair.
i had very light squirrel damage to the harness on my old Millenia, Every time it rained, the alarm, horn, lights, whatever would go off and I would have to disconnect the battery to regain control. Loved that car but it got to be too much. My ES replaced it, even better!
A good shop would remove the pins from the connector and slid on some shrink tubing and then tape up the wires. The miss fires are due to the wires shorting out.

I was afraid of that. I was hoping if I opened that box it goes into that I could simply replace the full length of the wire, connector to connector. Not so.

I wonder if I should be contacting an electrician instead, hah.
I was going to tape up the wires with electrical tape to at least get me to the dealer or repair shop, as long as the engine heat won't melt it and make things worse.
You could tape them yourself for the drive to the shop, just do it lightly so the shop can easily remove your tape. They will probably install shrink tubing as it will be weather proof and hold up much better than tape. You want an auto repair shop, not an electrician. If you need help finding a shop I always recommend starting with those recommended by the listeners of the Car Talk radio program with the guys Click and Clack that ran for years. https://www.cartalk.com/mechanics-files

I called the Toyota dealer to purchase a couple of the connector plugs in case those are bad, but was told they aren't sold separately and have to purchase the entire wire harness for $2K+. Ouch!
I thought I had found the right part # 90980-11875 based on what's printed on the plug: https://www.ebay.com/itm/4x-Toyota-L...t/283179498889
It looks right to me, but the Toyota dealer said that's for a headlight connection.
Just take it to a repair shop. You do not need any new parts, unless the shop wants to splice in some new wire, but wire is cheap. You are wasting your time trying to find parts. Time for professional help.
That’s an easy fix for a pro. Your plug is fine your wires are mostly fine just the insulation is gone. They can extract the pin from the harness, resolder a new piece of wire heat shrink it all and good as new. They will either take the wires with the pins from a donor harness that they always have laying around or they can crimp new pins on to a piece of wire. I did this to a 2012 Camry that I added a backup camera to the factory radio screen.

I wanted to bring the connectors in case the repair shop doesn't have the right ones on hand...the shop wants to splice in some new wire and wasn't sure whether the connectors they had would be an exact match.
I taped up the wires with electrical tape as a temporary measure to get me to the shop and expected the engine to run fine since the bare wires aren't crossing and touching anymore, but it feels the same as before.
Replacing ignition coil wire - what part?
