Firing Order is:

 1 - 6 - 5 - 4 - 3 - 2

#1 cylinder is the passenger side towards radiator (right next to the
DIS ignition module). The coil towers on your ignition module should
be labeled with the cylinder numbers: if not, the coil unit closest to
the radiator is 1 & 4, the middle one is 2 & 5, and the one furthest
away from the radiator is 3 & 6.
