They are not fully PnP for the 94+ cars, there are 4-5 wires that must be spliced into the harness. I provide color-coded instructions so if you can work a crimper, it's doable. I do not supply dwell reducers as I have found that most of my customers use standalone engine management. Boundary Engineering has dwell reducers IIRC.

Splicing is necessary, but it's not irreversible. You can buy a coil pack harness from a Miata recycler (I don't have any in stock sadly) and splice it into my harness quite easily. I did that on my car - the coils unplug using a factory connector. I wish there were a way to tap into the two coil pack connectors, but I haven't found the male end of that connector available anywhere yet.

It's probably very doable but not even remotely economically feasible for a kit. If you can source the connector, my harness will wire into it - you would just use the power, ground, and one trigger from one connector and only the trigger from the other connector.
One member here has done it, but did not use a cap or dwell reducer. My thoughts are he is not getting the full benefit of the setup, as not as much voltage in = not as much out. He said no problems with the coils over heating, but they are not at full power. I like to do things right, and want the full voltage.
Sav, whats up with cops for a 99?
