This is the picture i used to sort out my wiring, quite simple when doing it. All i looked for when choosing coil was the height mainly and that it uses same spark plug as what i was. CR9E, which the r6 does, and they work perfect. no need to buy the sub loom just the coils, but have to be patient when searching as most people list just one as a quantity of 4 to buy which is a pain, my first set was £35 and 2nd set for my zzr was £33. I then bought brand new electrical plugs for £11 of e-bay and they are perfect.
I used Tri-Rated cable which is miles better then normal stuff, then wrapped in normal insulation tape then a layer of Self-amalgamating tape for extra protection as i noticed my wires to coils before i cut them were solid and fked.
