OEM Tach out connection Info. All motec model ECU's
In order to get the OEM tach in a 3 gen rx7 to work with the Aux out for tach.
It will not work hooked up directly, you will need to jump off a Ingnition 12v switched wire spliced with a 1k resistor. This way the signal out from the ECU can be amplified to get the OEM tack working. As the motec ECU tach aux is to low for oem tach, reason for the 12v switched wire splice.
Good info for those that need it.
Thank yo
