So those coils have built-in ignitors.  I havent used these coils before but the pic below found online.  Pin 1 is the trigger wire as explained above.  Pin 2 is ground which should ideally be connected to a clean point on the cylinder head (not manifold etc).  Pin 3 is +12V, this should come from a relay that switches on and off with the ignition switch.

For the coils themselves? here's the first good result from google, which lines up exactly with what Adam said. Sounds like you want the sequential option

From a setup point of view about all you need to do is set the ignition mode to direct spark and enter suitable dwell times for your coils.

How do i know what dwell times for the coils?

Heres what I ran on a recent K20a build. These times were half way between those transcribed from a hondata K20 base map (bit higher by maybe 0.5), which are usually pretty close to stock honda, and a chart that motec published on the denso part number(bit lower by 0.2 ish I think). TBH either set of numbers seemed to run well.

make sure to set spark edge to falling as well for these coils.
