Ignition in my car will be of wasted spark system. This means that both cylinders compressing and exhausting get a spark. In the cylinder compressing, the spark will detonate the mixture - in the cylinder exhausting, the spark has no effect (wasted!). Cylinders 1&4 and cylinders 2&3 are grouped and have separate coils. The picture shows the double coil and HT-leads with the according labels. Principle circuit diagram explains how ignition is triggered according to crank position. If you want to know more, this
compendium is quite complete.
The coil has quite some weight and has to be secured with a bespoke bracket. I chose one of the front chassis rails as I want to route the HT(high tension)-cables from underneath the intake manifold.
Cheers.
