This actually sounds okay...
Only time will tell if it's effective or not once you start to crank the engine over.

The only specs I can find on the coils say 19 A max but I think that's for the internal ignitor to the coil and not the external power draw. I've read a single 20 or 25 A fuse is suitable for four coils. The 18 AWG sections are short - 12 in. at most. The 16 AWG portion is the longest being something like 6 ft.

If 20A is okay, max current would be around 10A...maybe 12A or 13A.
So we'll try and stick with 10A.
There are charts for reference for minimum wire gauge thickness versus current draw.
The 18AWG sections sound okay due to it's short run.
I would change the main lead to at least a 12AWG or even 10AWG.

I don't want to get the car started and then have to redo the wiring within a year. I didn't use splices and taps anywhere but I'm sure I could have gone with better material.

Well, everything can be updated.
It's a matter of how much you're willing to spend and labor...
