do i need a tach adapter to run the MSD digital
window switch on a GM 2.4l dohc?
i;m told it’s the pink wire on the IDI harness, but i’m
curious as to weather or not i’ll need an adapter.
??
i believe the 2.4 needs a tach adapter otherwise itll only read half the rpms…i cant remember for sure though
it reads 1/2 because of the wasted spark…
the MSD has a setting for 2 cylinder waste spark…
i just dont know if it works as is…
nevermind…
once connected to the white wire of the IDI harness, it read rpm just fine.
