Msd digital window switch

[Explosive]

Hey, so with the window switch, not using a tach adaptor and running as 1 cylinder. Are you tapping off a wire directly from the a coil pack or going to the computer under the kick panel ?

the best way for a good tach pick up that i found is #8 coil wire from the pcm. and use 1 cylinder mode
