Any knowledge of how to hook up an aftermarket tach to a GM DIS Coil system?
My son's 2000 Chevy Impala 9C1 does not have a factory tach. I have a couple of aftermarket tachs for him to choose from.
On a side note-after taking his car on vacation last week (we bought it about 2 months ago), I now know how much fun it is to drive an ex cop car.
Why not swap the cluster from an LS/SS and use a factory tach?

Otherwise, it sounds like the white wire described here will work if you're wanting to use a tach you have laying around:
