Hei tach wire

[O. D. Showtime]

Yes that's the wire with tach filter inline...the connector that is shown clips to the white wire....looks like the other ends is snipped off?

I just found that out and so anyone have a picture of the wire that goes into the Hei? And I am going through an old Monte Carlo ss harness so I guess it was snipped at one point

Some say yes some so no....I'd run it if I had it...I had some info on it I'll see what I can find...

**edit...found it...

The tach filter is exactly what its name indicates. It filters the high frequency interference generated by the solid state HEI so the tach sees only the firing pulses and not the interference. You can run without it, and if your HEI is elecrtically clean enough, you won't notice the difference. If you have electrically sloppy parts in the HEI, the interference they generate might cause the tach reading to fluctuate

Should be fine. Like he says, it can't really hurt and you can remove it if you think it is causing problems with the tach signal.
