There's no need to run a capacitor from what I've read/search, but to answer your question, the capacitor goes from your 12v to GND.

I'm assuming you're talking about Toyota COPS.

Upgrading to Coil on Plugs (all years) COP writeup

Did you read this? It's the first thing that pops up when you type "miata toyota cop". Should answer everything. Some use capacitors, some don't. If you have one, it wouldn't hurt, if you don't it's probably fine.

Yes, cap goes in the coil pack loom, not sure where else it'd go.

If you have it, wire the capacitor in, if you don't, don't worry about it. I don't have a capacitor in mine, and it's been running fine.

Toyota cops wont work with a stock ecu. stock ECU will blow the coils because of incorrect dwell.

this is untruth.

there are/were plenty of people running them on stock ECUs without any negative effects.

There was only an issue with NB setups, but it wasn't that they would blow, they simply wouldn't fire.


rleete just did it--after a bunch of naysayers said not to--and it's been fine.

Stock ECU, 1994 model. No issues whatsoever. Runs better, smoother. I've been driving the hell out of it for two weeks in blazing heat. No problems at all.
