easy way to remember fireing order.
I explain it like this to everyone who has the problem.

In Mazda terms,
T stands for Trailing,
L stands for Leading,
Then you have rotor housing 1,and rotor housing 2.
1 is closer to the front of the car (your left,when you are standing on the plug side) rotor housing 2 is on the right

How I explain it to people is,
T is for Top
L is for lower

L1,lower plug,rotor housing 1.
Easy to understand?
Also on the coils itself, its already labeled T1,T2 L1,L2
