Which spark plug are we firing with the EDIS-4, lead or trail ? I assume
the
wasted spark will be on the other.

Karibian, I dont propose using the waste spark plugs in the engine, just
wire them up off engine to provide stock electrical load or replace the
coils with a single plug coil on plug type. I plan on a second EDIS on the
trailing plugs for redundant ignition.
