As I understand:

There\'s 3 coil packs.

The rear most one goes to the top rear plug.

The middle coil pack is the leading sparks and sparks both plugs so it doesn\'t matter which of the 2 lower plugs each goes to, but one will be longer.

The front one goes to the front top plug.

I changed my leads this weekend, but this was also very useful ;)

as above but also:

if you have plugs 7s and 9s, 7s in the bottom and 9s in the top...if 9s all round then no problem.  (assuming you dont run a colder plug).

The middle coilpack is labeled L1 L2, the L1 goes to the front Rotor bottom Plug, L2 goes to the rear rotor bottom plug

A 99p E-bay workshop manual will tell you this info. Some stuff is specific to the US cars but most of it is relevant.
