Dumb Q- New Tach w/ HEI kills engine....

Seems simple enough to wire a tach, two leads and a ground.......

I bought an entire new tach dash, this is a Counterpart Automotive job.

Came with a Tach Harness and all........so one lead to bat switched and then the other lead goes that is for the coil, goes to the hei cap tach connection...........no seperate coil w/ hei.

as soon as i connect the tach harness, truck dies???

Yes the cluster has a very good ground......

Any thoughts?


Thanks!
