not rocket science Nick, no, but a tad more tricky than may first appear, to deal with all eventualities.. the "easy" way of rerouting the 2 ignition signals also has the limitation of coil on-time of the standard distributor setup. Extending the coil on-time to take full advantage of the DIS coilpack is a bit more involved..
An interesting point is, if you trace out the circuit, there is unused component positions on L8 that correspond to a second amplifier drive output.. .. work continues
