I'm getting a P0300 and was going to change spark plugs, coils, and wiring harness. But I can't seem to find the right spark plug wires- that plug in like a wiring harness clip.
So no change out on these wires?

Unless your engine has been replaced with a much earlier 3rz-fe (which had a distributor) or a post-2000 engine from a Tacoma (which will have coil-on-plug, COP) you have two coils, each with two leads, mounted on the engine block.
If you've got either of the other arrangements, considerable rewiring was done to make this happen. Or maybe it has some strange aftermarket "improved" ignition system.
Here are numerous sets of wires:

I've owned a 2000 4-cylinder 4Runner for 19 years, so I've looked at that engine many times. Mine still has the NGK wires a previous owner installed. It now has 240,000 miles.
Don't forget to check your 3rz-fe engine's valve clearances.
