With a 3rd gen do i connect the signal from the ignitor to the white wire on the msd or the purple and green wire? the manual says purple and green for a magnetic pickup or crank trigger. the white wire is for electonic ignition. which one do i use?

Thanks for the info it really helped. If the leading do 90% of the combustion than why do people use amps for the trailing coils?

to have an amp on every coil so they feel cool
