Been a long time since I posted. Been laid up for many months. Finally getting back to the car.

I may have asked this question before.

Using DD digital dash with HEI.

DD instructions state to not run a tach wire next to any signal wire.....which I understand.

But what is the minimum distance they can be apart to eliminate cross talk?

Thanks everyone
Tom

Just don't run it alongside a spark plug wire and you'll be alright. The tach is a real slow signal rate (6 cps at 6000 RPM) so interference isn't a problem.
