Holley/ MSD no help- innovate no Help J&S always helpful!!

Looks like Imay have afew options to pull a tachsignal soIdont over tax one....

2 CDI boxes each has tach signal out

J&S Safeguard also has a 12v square wave tach out put. Its the yellow wire in pin 3 of the connector and the output transistor is a 100v mosfet with a120 ohm 12v pull-up resistor. ( ihave zero idea what that means but hopefully its the ticket...

The innovate requires a 0-5v tach signal and worked when spliced into the black and violet tach wire off the CDI.
