27860, what is a "tach output terminal" and...
Posted by tim97rs, Jul-18-02 08:41 AM
do i have one with stock ignition? i just got an RPM activated on/off switch from mallory. Can i just connect this to my tach wire at the ecu? or is there a better one somewhere else?

You should be able to use the tach terminal at the ECU, but you will only read 1/2 actual RPM there due to your distributorless ignition. But that is no prob...just set the Mallory RPM switch to 1/2 of your desired RPM actuation point, and it will work fine!
enjoy,
Bill

i have my SAFC wired to the tach wire at the ECU and it reads the correct RPM, will i still read 1/2, or is that a completely different wire than what i need for the RPM switch? thanks
