Reply to "Duraspark vs MSD distributor"

I collected all the parts required for the switch to a DuraSpark I ignition, including the Painless wiring harness, and I need to point out that when I went to hook it all up after performing the mod to the tab on the Painless connector I discovered that the there is a difference in the 4 pin connector wiring between a I & II module. Not sure when this came about, but be aware that that two of the wires in the painless harness need to be switched in order to correctly connect to a Duraspark I module. The Orange (1/2 dizzy stator signal) and the Green (- coil) need to exchanged places. This step was not mentioned in the previous instructions and may not have been the case when those were first written. I have since located wiring diagrams for the Duraspark I and II modules and they indeed show a different pin out for the four pin connector.
