What would happen if you grounded the tach signal wire from the ICM?

My honda died on me the other night and I when I popped the hood the tach signal wire was grounded to the dizzy housing.

I was wondering if this would burn up a ICM?

What is the tach signal wire attached to? Remote start? Aftermarket tachometer? FMU?

Also what is the other end of the wire tied to? An injector? Straight to the ICM?
