Will the Mopar Electronic Ignition Conversion Disable My Tach?

I have a '66 Formula S with a factory tach. It uses the "tuna can" tach sending unit on the left kick panel under the dash.
My old dual-point distributor has a lot of side play, so I purchased the Mopar Electronic Ignition Conversion from Summit to replace it.
Has anyone installed this on a car with a factory tach? Does the tach still work? Or will that lead to another problem??
I appreciate your responses.
