Has anyone wired up a dual SDSEFI to the GRT EIS?
My main question is in regards to hooking up the tachs. The dual SDS has one 12v (yellow wire) and a 5v (green wire) tach output for the primary ECU and a 12v (yellow wire) tach output for the backup ECU.
The EIS has tach 1 & 2 input. Do I just wire up the 12v outputs and forget about the 5v output.
My goal here is to not see smoke when I hit the master for the first time.
Thanks
