Safest would be to go to the manufacturer of you tachs website and look at the instruction sheet there. Will tell you what wire to clip and what wires go to pos and neg.

The igniter itself has its tach output signal connector

Not when u use the igniter it can interrupter the work of the ignition
Not when you use msd box therefore you need to use the tach output

is this the tach wire im holding Bobby?
Re: ignition coil pack wiring info needed for rpm tac
There are 2 types of tacs - Voltage & Current.
I spent weeks trying to figure out how to wire a '62 Alpine (current) tac to a 3tc engine & igniter. The Alpine info says key sw. B+ thru a loop outside the tac to the coil +.
Surely that wouldn't work according to all the Toyota info. But it does work perfectly!
