Hope this helps, Nik.

There are 2 double coils.
One feeds the 1st and 4th cylinder and the other one the 2nd and 3rd ones.
Each coil fires up both cylinder, that is feeding, at the same time.
Each coil has 2 wires. The Red/White wire is common on both coils.
The Orange wire connects to the coil of 1st and 4th cylinder's plugs and the Gray wire to the coil of 2nd and 3rd cylinder's plugs.
