Check on my Wiring of the Junkyard HEI
There is only an average of 1 volt running through the distributor wires, so the worst thing that could happen if they touched is no signal from the distributor to the module and no spark.
No arcing, no wire burning, not even a spark from them if they touch.
BTW I used the 8 pin module and connectors on my car and have been carrying a spare module in the trunk for 5 years without ever needing it.
