I'd tap in after the tach amp, where it goes to the dash. otherwise you might atttenuate the signal to the point the tach amp freaks out.
Also, I'd think the amp would divide down the 140 or whatever pulses per rotation to a more manageable signal to send to the tach as well.
That assumes it picks up off of the ring gear, and not some other reference.
